The present disclosure relates to software, computer systems, and computer-implemented methods for providing access to vector data on a mobile device. Specifically, a user of a mobile device is provided with access to vector data (e.g., Computer-Aided Design (CAD) data) and can read and/or edit the vector data using the mobile device.
Vector data can be used for a variety of purposes in computing, navigation, construction work, logistics, research, and development. Vector data allows the use of computer systems to assist in the creation, modification, analysis, or optimization of a design of a physical object. Associated software may be used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Vector data is often in the form of electronic files for print, machining, or other manufacturing operations.
One example of vector data is Computer-Aided Design (CAD) data, which is used in many fields. The use of CAD in designing electronic systems is known as Electronic Design Automation (EDA). In mechanical design the use of CAD is known as Mechanical Design Automation (MDA) or computer-aided drafting, which includes the process of creating a technical drawing with the use of computer software.
CAD software for mechanical design uses vector-based graphics to depict the objects of traditional drafting. As in the manual drafting of technical and engineering drawings, the output of CAD may convey a variety of information, such as materials, processes, dimensions, and tolerances, according to application-specific purposes.
CAD may be used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) space. CAD is thus an important industrial art extensively used in many applications, including automotive, shipbuilding, and aerospace industries, industrial and architectural design, prosthetics, and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising and technical manuals, often called Digital content creation (DCC). Because of its enormous economic importance, CAD has been a major driving force for research and development in computational geometry, computer graphics (both hardware and software), discrete differential geometry, and computer-aided research and development.
However, due to the complexity and large size of vector data, it is an obstacle to provide access to vector data on mobile devices. Thus there exists a need for viewing and/or editing of vector data on mobile devices.
The present disclosure relates to software, computer systems, and computer-implemented methods for providing access to vector data on a mobile device. Specifically, a user of a mobile device is provided with access to Computer-Aided Design (CAD) data and can read or edit the CAD data using the mobile device.

The present disclosure relates to software, computer systems, and computer-implemented methods for providing access to vector data on a mobile device. In some instances, a user of a mobile device is provided with access to Computer-Aided Design (CAD) data and can read or edit the CAD data using the mobile device.
First, a user of a mobile device can read and modify vector data in an efficient manner by using image tiles displayed on the mobile device. For example, the user may directly access an interactive object displayed in association with the image tiles to modify the vector data associated with the image tiles. The large amount of vector data is located on the server-side, while the mobile device only needs to handle the much smaller sizes of image tiles. As the vector data is not transmitted to the clients and stays on the server, copyrights may not be infringed.
Second, the mobile device may perform a pre-processing to increase speed of subsequent (i) navigation across the vector data, or (ii) modification of the vector data.
Third, the user may query information related to the displayed image tiles and may be provided with the information.
Fourth, local construction work, logistic operations or machine development may be performed in a more efficient manner, e.g., by benefiting from mobile and rapid prototyping of physical objects. Additionally, most providers of vector data don't like to distribute their vector data directly, providing it in images helps them to keep their intellectual property.
The illustrated environment 100 of
In general, the client 150a, 150b includes a processor 144, an interface 152, a client application 146 or application interface, a graphical user interface (GUI), and a memory or local database 148. In general, the client 150a, 150b includes electronic computer devices operable to receive, transmit, process, and store any appropriate data associated with the environment 100 of
Both the input and output device may include fixed or removable storage media such as a magnetic storage media, CD-ROM, or other suitable media, to both receive input from and provide output to users of client 150a, 150b through the display, namely, the GUI. The client application 146 or application interface can enable the client 150a, 150b to access and interact with applications and modules in backend server systems using a common or similar platform. The client application may be a renderer application for image tiles (e.g., a software program, allowing the user to view and/or edit the image tiles). The client application 146 allows the client 150a, 150b to request and view content on the client 150a, 150b. In some implementations, the client application 150a, 150b can be and/or include a web browser. In some implementations, the client application 146 can use parameters, metadata, and other information received at launch to access a particular set of data from the server 102, 120. Once a particular client application 146 is launched, the client can process a task, event, or other information which may be associated with the server 102, 120. Further, although illustrated as a single client application 146, the client application 146 may be implemented as multiple client applications in the client 150a, 150b.
There may be any number of clients 150a, 150b associated with, or external to, environment 100. For example, while illustrated environment 100 includes one client 150a, 150b, alternative implementations of environment 100 may include multiple clients communicably coupled to the one or more of the systems illustrated. In some instances, one or more clients 150a, 150b may be associated with administrators of the environment, and may be capable of accessing and interacting with the settings and operations of one or more network applications, and/or other components of the illustrated environment 100. Additionally, there may also be one or more additional clients 150a, 150b external to the illustrated portion of environment 100 capable of interacting with the environment 100 via the network 140. Further, the terms “client,” “customer,” and “user” may be used interchangeably as appropriate without departing from the scope of this disclosure. Moreover, while the client 150a, 150b is described in terms of being used by a single user, this disclosure contemplates that many users may use one computer, or that one user may use multiple computers. In general, clients may usually belong to one customer or company. Several employees of the customer, called users, can use the applications deployed on the corresponding client. For instance, the term “client” refers to a system providing a set of client applications belonging to or rented by a particular customer or business entity. Several employees of that particular customer or business entity can be users of that client and use the network applications provided by or available on this client.
The data stored in the local database 148 may be locked and accessed by the first backend server 102, and interacted with the front-end client 150a, 150b. In other instances, the data may be used by a Rendering Process Engine 108 associated with one of the other backend servers 120 for processing applications associated with those systems. For example, one or more of the components illustrated within the backend servers 102, 120 may be located in multiple or different servers, cloud-based or cloud computing networks, or other locations accessible to the backend servers 102, 120 (e.g., either directly or indirectly via network 140). For example, each backend server 102, 120 and/or client 150a, 150b may be a Java 2 Platform, Enterprise Edition (J2EE)-compliant application server that includes technologies such as Enterprise JavaBeans® (EJB), J2EE Connector Architecture (JCA), Java Messaging Service (JMS), Java Naming and Directory Interface (JNDI), and Java Database Connectivity (JDBC). In some instances, each of the backend servers 102, 120 may store a plurality of various applications, while in other instances, the backend servers 102, 120 may be dedicated servers meant to store and execute certain network applications built based on the on-demand platform using the on-demand platform technology and on-demand platform business content. In some instances, the images may be replicated to other locations (e.g., another backend server) after they are generated from one backend server. In some instances, the backend servers 102, 120 may include a web server or be communicably coupled with a web server, where one or more of the network applications 108 associated with the backend servers 102, 120 represent web-based (or web-accessible) applications accessed and executed through requests and interactions received on the front-end client 150a, 150b operable to interact with the programmed tasks or operations of the corresponding on-demand platform and/or network applications.
At a high level, the backend servers 102, 120 include an electronic computing device operable to receive, transmit, process, store, or manage data and information associated with the environment 100. The backend servers 102, 120 illustrated in
As used in the present disclosure, the term “computer” is intended to encompass any suitable processing device. For example, although
The first backend server 102 is illustrated in detail in
In
The term “network” refers to all or a portion of an enterprise or secured network, while in another instance, at least a portion of the network 140 may represent a connection to the Internet. In some instances, a portion of the network 140 may be a virtual private network (VPN). Further, all or a portion of the network 140 can include either a wireline or wireless link. Example wireless links may include 802.11a/b/g/n, 802.20, WiMax®, and/or any other appropriate wireless link. In other words, the network 140 encompasses any internal or external network, networks, sub-network, or combination thereof operable to facilitate communications between various computing components inside and outside the illustrated environment 100. The network 140 may communicate, for example, Internet Protocol (IP) packets, Java Debug Wire Protocol (JDWP), Frame Relay frames, Asynchronous Transfer Mode (ATM) cells, voice, video, data, and other suitable information between network addresses. The network 140 may also include one or more local area networks (LANs), radio access networks (RANs), metropolitan area networks (MANs), wide area networks (WANs), all or a portion of the Internet, and/or any other communication system or systems at one or more locations.
As illustrated in
At a high level, the term “software application” and “networked application” described in this specification refer to any application, program, module, process, or other software that may execute, change, delete, generate, or otherwise manage information associated with the server 102, 120 or the client device 150a, 150b, and in some cases, a business process performing and executing business process-related events. In particular, business processes communicate with other users, applications, systems, and components to send, receive, and process events. In some instances, a particular Rendering Process Engine 108 may operate in response to and in connection with one or more requests received from an associated client or other remote client. Additionally, a particular Rendering Process Engine 108 may operate in response to and in connection with one or more requests received from other network applications external to the backend server 102. In some instances, the Rendering Process Engine 108 can be a networked application, for example, the Rendering Process Engine 108 is built on a common platform with one or more applications in either or both of the backend servers 120 and 102. In some instances, the Rendering Process Engine 108 may request additional processing or information from an external system or application. In some instances, each Rendering Process Engine 108 may represent a web-based application accessed and executed by the front-end client 150a, 150b via the network 140 (e.g., through the Internet, or via one or more cloud-based services associated with the Rendering Process Engine 108).
Further, while illustrated as internal to the backend server 102, one or more processes associated with a particular Rendering Process Engine 108 may be stored, referenced, or executed remotely. For example, a portion of a particular Rendering Process Engine 108 may be a web service that is remotely called, while another portion of the Rendering Process Engine 108 may be an interface object or agent bundled for processing at a remote system. Moreover, any or all of a particular Rendering Process Engine 108 may be a child or sub-module of another software module or enterprise application (e.g., the backend servers 120 and 130). Still further, portions of the particular Rendering Process Engine 108 may be executed or accessed by a user working directly at the backend servers 102, as well as remotely at corresponding front-end client 150a, 150b.
Regardless of the particular implementation, “software” may include computer-readable instructions (e.g., programming code), firmware, wired or programmed hardware, or any combination thereof on a tangible and non-transitory medium operable when executed to perform at least the processes and operations described herein. Indeed, each software component may be fully or partially written or described in any appropriate computer language including C, C++, Java®, Visual Basic®, assembler, Perl®, any suitable version of 4GL, as well as others. It will be understood that while portions of the software illustrated in
In some implementations, the server 102, 120 can communicate with client device 150a, 150b using the hypertext transfer protocol (HTTP) or hypertext transfer protocol secure (HTTPS) requests. In some implementations, the server 102, 120 can use a remote function call (RFC) interface to communication with advanced business application programming (ABAP) language and/or non-ABAP programs, e.g. ODBC requests.
The memory 109 or tile cache 110 may store various image tiles, business objects, object models, and data, including classes, frameworks, applications, backup data, business objects, jobs, web pages, web page templates, database tables, process contexts, repositories storing services local to the backend server 120 and any other appropriate information including any parameters, variables, algorithms, instructions, rules, constraints, or references thereto associated with the purposes of the backend server 120 and its functionality. In an aspect, the term “business object” is a representation of an intelligible business or non-business entity, such as an account, an order, employee, an invoice or a financial report. In some implementations, including in a cloud-based system, some or all of the memory 110 may be stored remote from the backend server 120 and communicably coupled to the backend server 120 for usage. As described above, memory 110 can include one or more meta-models associated with various objects included in or associated with the underlying platform. Specifically, memory 109 or tile cache 110 can store items, tiles, and entities related to the Rendering Process Engine 108 and/or other collaboration-related entities or components. Some or all of the elements illustrated within memory 109 or tile cache 110 may be stored external to the memory 109 or tile cache 110.
In an aspect of the implementations described herein, a system 100 for providing access to vector data on a mobile device 150a, 150b may comprise: a mobile device 150a, 150b; a server 102, 120 remote from the mobile device 150a, 150b; the mobile device 150a, 150b configured to: transmit, from the mobile device to the remote server, one or more requests for first vector data, the requests specifying the first vector data, a display property of the mobile device, a first zoom level and a location within the vector data; and the remote server 102, 120 configured: determine, based on the one or more requests, one or more image tiles representing information of the requested first vector data; and provide the one or more image tiles to the mobile device for display.
In many applications it can be helpful to display CAD data. There are different ways to do this. In one example, CAD data can be transported to the client 150a, 150b and rendered there. Another possibility is to render the data on the server 102, 120 and transport an image representing the rendered data to the client 150a, 150b. There are at least two possibilities to do this. In one instance, a single image is rendered using the CAD data and completely transported to the client 150a, 150b. A second possibility is tile-based rendering. This application describes this possibility, which is shown as the ‘CAD Data’→‘Render on Server’→“Tile based Rendering” branch in
The tile-based rendering may be based the level of detail (lod) or zoom level. In an exemplary embodiment, whenever the level of detail or zoom level is incremented by one, the number of tiles gets quadrupled. As illustrated in the example of
See here for details: http://msdn.microsoft.com/en-us/library/bb259689.aspx. To optimize the indexing and storage of tiles, the two-dimensional tile XY coordinates are combined into one-dimensional strings called quad tree keys, or “quad keys” for short. Each quad key uniquely identifies a single tile at a particular level of detail, and it can be used as an key in common database B-tree indexes. To convert tile coordinates into a quad key, the bits of the Y and X coordinates are interleaved, and the result is interpreted as a base-4 number (with leading zeros maintained) and converted into a string. The data is stored in a 3D matrix with the X,Y, and zoom level dimensions.
Three-dimensional (3D) data can be stored in an enhanced Quad Key plus view-angle interface. Quad Key plus view-angle interface in 3D may be realized as followed:
3D navigation ground based graphics:
1. Definition of 3D navigation ground based graphics:
2. Spatial Limitations:
The number of rendered images may be then:
Number of locations*Number of camera angles*Number of inclination angles*Number of rotation angles
This can be arranged in a 5 dimensional matrix analogous to the quad key interface. (Coordinates: x,y, camera zoom (camera angle), inclination, rotation). Quad keys may provide a one-dimensional index key that usually preserves the proximity of tiles in XY space. In other words, two tiles that have nearby XY coordinates usually have quad keys that are relatively close together. This may be useful for optimizing database performance, because neighboring tiles are usually requested in groups, and it's desirable to keep those tiles on the same disk blocks, in order to minimize the number of disk reads.
The rendering process engine 108 (see
In an aspect, the location in request 401 includes two-dimensional tile coordinates, and the generating, by the remote server, of the one or more image tiles from the rendered vector data may include: combining the coordinates into a one-dimensional string, which identifies the image tiles at the zoom level. In an aspect, the process 400 may further comprise: before the receiving of the one or more requests, performing, by the mobile device, a pre-processing, the pre-processing comprising: constructing one or more additional requests for additional vector data associated with the requested vector data, the additional requests specifying the additional vector data; and determining, by the remote server and based on the one or more additional requests, one or more additional image tiles representing information of the requested additional vector data; providing, by the remote server, the one or more additional image tiles to the mobile device for display. For example, the additional requests specify one or more other zoom levels, and wherein the additional vector data is data associated with the other (e.g. one zoom level higher or lower than the initial zoom level in the request 401) zoom levels, or wherein the additional requests specify one or more other (e.g. neighboring) locations, and wherein the additional vector data is data associated with the other locations.
In an aspect, the process 400 may further comprise: receiving, by the server and from the mobile device, a query for data associated with an object (e.g. the location of an object within the vector data) within the image tiles; retrieving the data associated with the object from metadata associated with the first vector data; providing, by the remote server, the retrieved data associated with the object to the mobile device for display. For example, the user may be interested in locations of fire extinguishers within a building, which is at least partially displayed in the image tiles on the mobile device. In response to the query, the mobile device may receive, from the server, search results including the locations of the objects of interest. For example, the server may update the image tiles displayed on the mobile device, wherein the updated image tiles include highlighted information derived from the search results. For example the updated image tiles may include highlighted locations of the object within the building (e.g. all locations where fire extinguishers are located within the relevant building).
The process operation 501 may further comprise: performing, by the mobile device, a pre-processing, the pre-processing comprising: determining a required number of the image tiles associated with the requested vector data based on the zoom level and a size of the display of the mobile device; and transmitting, before the receiving of the one or more image tiles, the determined number of the image tiles to the remote server, wherein the number of the received one or more image tiles is substantially equal to the required number of the image tiles. The process operation 501 may further comprise: performing, by the mobile device, a pre-processing, the pre-processing comprising: constructing one or more additional requests for additional vector data associated with the requested vector data, the additional requests specifying the additional vector data; and transmitting, by the mobile device, the one or more additional requests to the remote server; and receiving, by the mobile device and from the remote server, one or more image tiles representing information of the requested additional vector data. In an aspect, the additional requests specify one or more other (e.g. higher or lower) zoom levels, and wherein the additional vector data is data associated with the other zoom levels, or wherein the additional requests specify one or more other (e.g., neighboring) locations, and wherein the additional vector data is data associated with the other locations.
The process operation 503 may further comprise: transmitting, from the mobile device to a remote server, a command to modify the first vector data (e.g. to add, remove, update or modify an object in the vector data, as illustrated in
The process operation 503 may further comprise: displaying, by the mobile device, the one or more image tiles; receiving a user navigation with respect to the displayed image tiles; and pre-fetching (e.g., storing image tiles requested and received from the server in a memory on the mobile device) additional information along a dimension of the user navigation, wherein more information is pre-fetched for the dimension in which the user navigation is the fastest. For example, the dimension includes at least one of zoom level, X coordinate of the display area, or Y coordinate of the display area (see example in
The process operation 503 may further comprise: receiving, at the mobile device, one or more requests for second vector data different from the first vector data, the second requests specifying the second vector data; determining, by the mobile device, that the requests for the first vector data are likely of lower priority than the requests for the second vector data; initiating, by the mobile device, the remote server to prioritize the requests for the second vector data over the requests for the first vector data; transmitting, by the mobile device, the requests for the second vector data to the remote server; and receiving, by the mobile device and from the remote server, one or more image tiles representing information of the requested second vector data. For example, the mobile device may determine that the first request for first vector data is not needed or invalid any may cause stopping of the processing (e.g., by the server) of this request or may make the second request top priority for the server-side processing illustrated in
As illustrated in
As illustrated in
In an aspect, the GUI 600 may further provide the user of the mobile device 150a, 150b with the possibility to submit queries for metadata associated with the vector data with which the displayed image tiles are associated. For example, one or more of the icons 602 may include a query field configured to receive a user query for data associated with an object (e.g. the location of an object within the vector data) within the image tiles, and to cause the remote server 102 to retrieve the data associated with the object from metadata associated with the vector data. The server may subsequently provide the retrieved data associated with the object to the mobile device for display. For example, the user may be interested in locations of electrical wires or plugs in the area of the wall 603. In response to the query, the mobile device may receive, from the server, search results including the locations of the objects of interest. For example, the server may update the image tiles 605 displayed on the mobile device, wherein the updated image tiles include highlighted information derived from the search results. For example the updated image tiles may include highlighted locations of the object within the building (e.g. all locations where electrical wires or plugs are to be placed). 601 and 605 may be one or more image tiles, which may be invisible to the user of the mobile device 150a, 150b.
According to one or more embodiments described herein, the user may perform a mobile and rapid prototyping of a design of physical objects, e.g., at a construction side. The user may change vector data (e.g. CAD data) through changing image tiles (e.g. in jpeg, gif, tif or png format).
At 706, the mobile device 150a, 150b receives or identifies one or more requests for first vector data and transmit the requests to the server 102 via the network connection. The requests may specify the first vector data, a display property (e.g. size and/or screen resolution) of the mobile device, and a first zoom level and a location (e.g., (X; Y) coordinates) within the vector data.
At 707, the remote server 102 determines, based on the one or more requests, one or more image tiles representing information of the requested first vector data. The determining, by the remote server (e.g., by rendering process engine 108 in
At 709, the remote server 102 provides the one or more generated or retrieved image tiles to the mobile device 150a, 150b, which displays the received image tiles.
At 710, the mobile device transmits a command to the server, wherein the command requests a modification of the first vector data. Referring to
At 711, the server identifies relevant vector data of the first vector data to be modified and modifies the relevant vector data according to the received command. Then, the server (e.g., the rendering process engine 108 in
At 712, the remote server 102 provides the one or more modified image tiles (e.g., image tiles 605 in
