DETAILED DESCRIPTION OF EMBODIMENTS

To make the objectives, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings. It is apparent that the embodiments to be described are merely part of rather than all the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without the exercise of any inventive skill fall within the protection scope of the present disclosure.

The embodiments of the present disclosure may be applied to the simulation process of animation effects, i.e., the process of simulating animation effects through a large number of particles. Wherein the animation effects are image effects formed by the motion of a large number of particles, including but not limited to, fireworks effects, cloud effects, volcanic eruption effects, flames effects.

FIG. 1 shows a schematic diagram of the rising process of fireworks, and FIG. 2 shows a schematic diagram of fireworks exploding after rising to a certain location. With reference to FIG. 1, multiple particles form fireworks moving upward from the bottom, and with reference to FIG. 2, the fireworks explode when these particles rise to a certain location.

It can be seen that the above fireworks effect is realized through particle effect, which refers to the ability encapsulation of special rendering effects.

The above particles have a life cycle, which consists of an initialization stage, an update stage and a rendering stage.

Wherein the initialization stage is used for defining an initial state of the particle, i.e., the initialization of attributes of the particle, such as the location, size, color and velocity of the particle.

The update stage is used for updating attributes of the particle during motion, including color, transparency, size, location, and direction of motion. Transparency is the alpha channel of the color, with a value range usually between 0 and 1, wherein alpha=1 means opaque, alpha=0 means completely transparent. In addition to the above-mentioned attributes of particle that need to be updated, attributes of the particle further include some attributes that do not need to be updated, such as the lifetime and mass of the particle.

The rendering stage is used for displaying the particle subsequent to being initialized or updated. During display, the particle may be replaced with a model, which may be a two-dimensional or three-dimensional model. The rendering process may be implemented using a rendering pipeline, which is a geometry shader for processing vertex information in real time and generating geometry. The working mode of the rendering pipeline may comprise three: a point mode, a triangular faceted mode, and a quad faceted mode. In the point mode, particles rendered by the rendering pipeline are points. In the triangular faceted mode, particles rendered by the rendering pipeline are triangles. In the quad faceted mode, particles rendered by the rendering pipeline are quadrilaterals.

In the prior art, the speed of the above particles during motion is fixed. In reality, however, fireworks, flames, volcanic eruptions and clouds are affected by the environment and other factors, and thus do not move at fixed speed. This, in turn, results in a less realistic simulated animation effect.

To solve the above-described problem, the embodiments of the present disclosure may determine the location of a particle during motion through a motion control parameter. Since the motion control parameter is a parameter that affects the motion, it is possible to simulate the motion of an object in a real environment and improve the authenticity of the animation effect.

By way of several specific embodiments, a detailed illustration is presented below to the technical solution of the embodiments of the present disclosure and how to solve the above technical problem by the technical solution disclosed herein. These specific embodiments may be combined with each other, and the same or similar concepts or processes might not be repeated in some embodiments. With reference to the accompanying drawings, the embodiments of the present disclosure are described below.

FIG. 3 shows a flowchart of the steps of a method of simulate object motion by particles provided by an embodiment of the present disclosure. The method shown in FIG. 3 may be applied in an electronic device. With reference to FIG. 3, the method of simulate object motion by particles comprises:

S101: generating a first number of particles, each comprising one or more pixel points, the motion process of the first number of particles forming an animation effect, which is used for simulating a motion effect of the object in a real environment.

When generating the first number of particles, at least one of attributes of the first number of particles in an initial state may be set: a shape formed by the first number of particles, a size of the shape, a color of each particle, a location of each particle, and a speed of each of the particles.

Wherein the shape may be a two-dimensional shape, such as a rectangle, a circle, a trapezoid, and an irregular figure. Of course, the shape may further be a three-dimensional shape, such as a cube, a sphere, a cylinder, an irregular geometry.

The size of the shape needs to be determined based on the dimension of the shape. For example, regarding a two-dimensional shape, it may be represented through a length, and/or width, and/or height, and/or area; regarding a three-dimensional shape, it may be represented through a length, and/or width, and/or height, and/or volume.

It is noteworthy that different particles may have the same or different colors, have different locations, and have the same or different speed.

Certainly, the location of the particles is an initial location and needs to be updated through S102 so as to reflect the rising process of the particles.

To generate the first number of particles, the embodiments of the present disclosure provide two examples.

In a first example, the first number of particles may be randomly generated. That is, the location of each particle is randomly set, the speed of each particle is randomly set, and the color of each particle is also randomly set. Of course, if it is necessary to guarantee that the first number of particles form a target shape with a target size, the location of the particles may be defined based on the target size and target shape.

In the embodiments of the present disclosure, to further enrich the display effect of animation effects, the particles may be arranged into a target display object, which may be text, a pattern, etc.

In a second example, first of all, a second number of particles are randomly generated; then, particles located in a target image area in the second number of particles are determined as the first number of particles, the target image area including particles needed to form the target display object.

Wherein the second number is greater than the first number, and the algorithm of generating the second number of particles may be referred to the process of generating the first number of particles in the first example, which is not detailed here.

Based on the second number of particles, the first number of particles may be filtered out from the second number of particles through the target image area. The target image area is related to the type of the target display object.

When the target display object is text, the target image area is an image area where strokes of the text are located. FIG. 4 shows a schematic diagram of a target image area that is text as provided by the embodiments of the present disclosure. With reference to FIG. 4, the image area where the strokes of the text “hello” is the target image area, and the blank area between the letters “he,” “ll” and “o” as well as the rest of the blank area is a non-target image area. Wherein the target image area may be obtained from a standard delay format (SDF) file, which is also referred to as a text map.

When the target display object is a pattern, the target image area is an image area where an effective part of the pattern is located. FIG. 5 shows a schematic diagram of a target image area that is a pattern as provided by the embodiments of the present disclosure. With reference to FIG. 5, an area formed by the outline of the flower is the target image area, and the remaining area outside the outline of the flower is a non-target image area.

S102: updating a location of the particles based on a motion control parameter during the motion process, the motion control parameter being a parameter that affects the motion.

Specifically, each time the location of the particles is updated, the acceleration may first be determined based on the motion control parameter, and then the location of the particles may be determined based on the acceleration.

The motion control parameter is related to a simulation environment. When the simulation environment is space, the motion control parameter is a gas resistance parameter and gas interference parameter in space; when the simulation environment is the earth, the motion control parameter includes a gravity parameter, air resistance parameter and air disturbance parameter.

When the motion control parameter includes the gravity parameter, air resistance parameter and air disturbance parameter, the process of determining the acceleration may comprise: first, determining a vector sum of the gravity parameter, air resistance parameter, and air disturbance parameter; and then, calculating a ratio of the vector sum to a preset particle mass to obtain the acceleration.

After obtaining the acceleration, the location of the particles is updated based on the acceleration, and the updated location is a sum of the location and distance before the update. When the location of the particles is updated for the first time, the location before the update is the location set in S101.

Based on the embodiments of the present disclosure, the acceleration may be determined through the gravity parameter, the air resistance parameter and the air disturbance parameter, so that the simulated rising process of the particles is affected by the gravity, air resistance, air disturbance and other factors, which improves the authenticity of the fireworks.

The updating the location of the particles through the motion control parameter may relate to each particle or one of the particles. For example, for the particle at the center location, the location of the particle is updated through the motion control parameter, while the location of the rest of the particles is updated based on the location of the particle. That is, the location of the rest of the particles is updated under the condition that the relative location relationship between the particles remains unchanged.

S103: displaying the particles based on the updated location of the particles.

Specifically, the particles are displayed at the updated location of the particles. Of course, while displaying the particles, the color of the particles is also considered.

It is noteworthy that in practical application, the location of the particles needs to be updated continuously, and the particles need to be displayed after each update of the location of the particles. That is, S102 and S103 are continuously performed at preset time intervals. For example, S102 and S103 may be performed once every t millisecond.

In practical application, objects in motion will have a trailing phenomenon due to visual delays. That is, for fast moving objects, we will see that there is a trailing in the motion process. The embodiments of the present disclosure may realize this trailing phenomenon by continuously decreasing the pixel value of the image of the previous frame to further improve the richness of the animation effect. Specifically, when displaying the particles based on the updated location of the particles, first of all, a first image displayed at a previous moment may be obtained, the first image comprising the first number of particles; then, a pixel value of each pixel point included in the particles in the first image is reduced to obtain an updated first image; afterwards, a second image is generated based on the updated first image and the updated location of the particles; finally, the second image is displayed, the second image comprising the pixel points with reduced pixel values and the first number of particles with the updated location.

Wherein the first image is the image displayed at a previous moment, and the second image is the image with a trailing effect at a current moment. As time elapses, the second image turns into the first image, so the second image needs to be continuously generated based on the first image.

FIG. 1 shows a second image P1 displayed at a moment t1. Since the particles are generated at the moment t1, there is no moment prior to t1, and further P1 only comprises the particles generated at the current moment t1.

At a moment t2, first, the second image P1 displayed at t1 is used as a first image at t2; then, the pixel value of each pixel point in P1 is reduced to obtain an updated P1; afterwards, a second image P2 displayed at t2 is generated based on the updated P1 and the location of the particles updated at t2. FIG. 9 is a schematic diagram of a second image displayed at t2. With reference to FIG. 9, P2 not only comprises each pixel point in the updated first image P1 corresponding to the location LOC1 of the particles at t1, but also comprises particles in the location updated as LOC2 at t2.

At a moment t3, first, the second image P2 displayed at t2 is used as a first image at t3; then, the pixel value of each pixel point in P2 is reduced to obtain an updated P2; afterwards, a second image P3 displayed at t3 is generated based on the updated P2 and the location of the particles updated at t3. FIG. 10 is a schematic diagram of a second image displayed at t3. With reference to FIG. 10, P3 not only comprises each pixel point in the updated first image P2 representing that the particles are in the location LOClat t1 and in the location LOC2 at t2, but also comprises particles in the location updated as LOC3 at t3.

At a moment t4, first, the second image P3 displayed at t3 is used as a first image at t4; then, the pixel value of each pixel point in P3 is reduced to obtain an updated P3; afterwards, a second image P4 displayed at t4 is generated based on the updated P3 and the location of the particles updated at t4. FIG. 11 is a schematic diagram of a second image displayed at t4. With reference to FIG. 11, P4 not only comprises each pixel point in the updated first image P3 representing that the particles are in the location LOC1 at t1, in the location LOC2 at t2 and in the location LOC3 at t3, but also comprises particles in the location updated as LOC4 at t4.

At a moment t5, first, the second image P4 displayed at t4 is used as a first image at t5; then, the pixel value of each pixel point in P4 is reduced to obtain an updated P4; afterwards, a second image P5 displayed at t5 is generated based on the updated P4 and the location of the particles updated at t5. FIG. 12 is a schematic diagram of a second image displayed at t5. With reference to FIG. 12, P5 not only comprises each pixel point in the updated first image P4 representing that the particles are in the location LOC1 at t1, in the location LOC2 at t2, in the location LOC3 at t3 and in the location LOC4 at t4, but also comprises particles in the location updated as LOC5 at t5.

At a moment t6, first, the second image P5 displayed at t5 is used as a first image at t6; then, the pixel value of each pixel point in P5 is reduced to obtain an updated P5; afterwards, a second image P6 displayed at t6 is generated based on the updated P5 and the location of the particles updated at t6. FIG. 13 is a schematic diagram of a second image displayed at t6. With reference to FIG. 13, P6 not only comprises each pixel point in the updated first image P5 representing that the particles are in the location LOC1 at t1, in the location LOC2 at t2, in the location LOC3 at t3, in the location LOC4 at t4 and in the location LOC5 at t5, but also comprises particles in the location updated as LOC6 at t6.

Optionally, the updated first image may be generated through the following process: regarding each pixel point comprised in each particle in the first image, determining a product of a predetermined reduction coefficient and a pixel value of the pixel point as a pixel value of the pixel point in the updated first image, the predetermined reduction coefficient being less than 1.

Wherein the pixel value is taken for the three colors red green blue (RGB). In this way, the pixel value of the first image can be constantly reduced by multiplying the pixel value by a value less than one. As time elapses, for the particle whose position is updated at a moment farther away from the current moment, the RGB values of the pixels it includes are smaller, and for the particle whose position is updated at a moment closer to the current moment, the RGB values of the pixels it includes are the largest.

In practical application, when an object moves to a certain degree, the object will explode. For example, when fireworks rise to a certain degree, the fireworks will explode. The embodiments of the present disclosure may use two examples in order to realize the fireworks explosion effect.

In a first example, after S102 and S103 are performed one or multiple times, the attributes of the particles might satisfy a predetermined condition, i.e., the speed of the particles reaches a target speed, and/or the motion of the particles arrives at a target location. At this point, the distance between two adjacent particles may be increased; the particles are displayed based on the increased distance. Due to the increasing distance between the particles, the image area formed by the particles also expands, so that the explosion effect of fireworks is realized.

Wherein the target speed may be 0 or close to 0. It can be understood that since the particles will be affected by gravity and air resistance during rising, their speed will gradually decrease till to 0. At this point, increasing the distance between two adjacent particles will achieve the explosion of fireworks.

The target location may be any location in the rising process. The embodiments of the present disclosure may realize the explosion of fireworks before the speed of the particles decreases to 0, thereby improving the flexibility of fireworks explosion.

In a second example, after S102 and S103 are performed once or multiple times, the attributes of the particles might satisfy a predetermined condition, i.e., the speed of the particles reaches a target speed, and/or the motion of the particles arrives at a target location. At this point, a predetermined image sequence may be played, and a particle area included in any image in the predetermined image sequence is larger than a particle area included in a previous image.

Wherein the target speed and the target location may be referred to the above detailed illustration of the first example, which is not repeated here.

FIG. 6 shows a schematic diagram of an image sequence provided by the embodiments of the present disclosure. With reference to FIG. 6, 56 frames of images are arranged in the order from top to bottom and from left to right, and the particle areas included in these 56 frames of images become increasingly large, so that the explosion effect of the fireworks can be realized by playing the images in this order.

As seen from FIG. 6 further, the transparency of the particles become increasingly small in the order from top to bottom and from left to right, thereby realizing the dissipation of the fireworks during the explosion.

In the embodiments of the present disclosure, in increasing the distance between two adjacent particles, the distance can be increased at a fixed speed, that is, the distance between the particles is increased by a fixed multiple at fixed intervals; the distance can also be increased at a variable speed, that is, the distance between the particles is increased by a variable multiple at fixed intervals.

In order to increase the distance at a variable speed, first of all, a gradually decreasing amplifying speed may be generated; then, the amplifying speed is inputted to a first preset function to obtain an amplifying factor, the first preset function being used for increasing the amplifying factor based on different increasing speeds as the amplifying speed decreases gradually; finally, the distance between two adjacent particles is increased based on the amplifying factor.

Wherein the amplifying speed evenly decreases as time elapses. That is, the amplifying speed decreases at a fixed speed. In practical applications, the decreasing speed of the amplifying speed and an initial amplifying speed may be set, so that the amplifying speed at each time may be determined and further the amplifying factor at the time may be determined based on the amplifying speed.

In order to realize a variable increasing speed of the amplifying factor while the amplifying speed evenly decreases, the first preset function may be a function with different derivatives in different value ranges. The embodiments of the present disclosure may increase the distance between two adjacent particles through an ever-changing amplifying factor, which helps to improve the richness of the explosion effect of particles.

Further, the amplifying factor increases at a first increasing speed, a second increasing speed, a third increasing speed and a fourth increasing speed in this order, the first and third increasing speeds being less than or equal to a preset threshold, the second and fourth increasing speeds being grater than or equal to the preset threshold. In this way, fireworks may quickly expand at the beginning of the explosion, and tend to be stable when reaching a certain size. That is, the size changes slowly, and fireworks can be clearly watched. Afterwards, fireworks quickly expand and tend to be stable when reaching a given size. That is, the size changes quickly when fireworks are going to dissipate.

It is noteworthy that the above preset threshold is a value approximating 0.

In order to realize the relationship between the amplifying factor and the amplifying speed, the embodiments of the present disclosure propose the following formula:

$\begin{array}{cc}\mathrm{SL}=c·\left(1.1-a·{\left(3·{\mathrm{AS}}^2-2·{\mathrm{AS}}^3\right)}^{10}-b·\left(1+{\left(3{\left(\mathrm{AS}-1\right)}^2-2{\left(\mathrm{AS}-1\right)}^3\right)}^{10}\right)\right)& \left(1\right)\end{array}$

where

$a=\{\begin{array}{cc}1,& 1\le \mathrm{AS}\le 1\\ 0,& 1<\mathrm{AS}\le 2\end{array},b=\{\begin{array}{cc}0,& 1\le \mathrm{AS}\le 1\\ 1,& 1<\mathrm{AS}\le 2\end{array},$

SL is the amplifying factor, AS is the amplifying speed, c is a constant greater than 1.

Based on Formula (1), FIG. 7 shows a schematic diagram of a relationship between the amplifying speed and the amplifying factor as provided by the embodiments of the present disclosure. In FIG. 7, the horizontal axis represents the amplifying speed, and the vertical axis represents the amplifying factor. As seen from FIG. 7, as the amplifying speed decreases, the amplifying factor first increases quickly and then tend to be gentle, i.e., no longer increases, and then quickly increases again and tend to be gentle.

Further, the embodiments of the present disclosure can simulate the dissipation process of the fireworks after explosion through the transparency of particles. The transparency is the largest at the beginning of the explosion, which represents that the fireworks do not dissipate yet. Then the transparency gradually decreases over time, which represents that the fireworks gradually dissipate, until the transparency decreases to a preset transparency. The preset transparency may usually be 0. Since only a small amount of computation is involved in modifying the transparency, the computation complexity needed to simulate the fireworks dissipation is effectively reduced.

In the embodiments of the present disclosure, when reducing the transparency, the transparency can be made synchronous with the amplifying speed based on the decrease of the amplifying speed, which improves the richness of the explosion of fireworks. Specifically, the transparency of the particles is reduced based on the amplifying speed, so that when displaying the particles based on the increased distance, the reduced transparency of the particles needs to be considered. That is, the particles are displayed based on the increased distance and the reduced transparency of the particles.

Wherein the transparency may be a function of the amplifying speed. In the embodiments of the present disclosure, the function may be referred to as a second preset function. The second preset function may output the gradually decreasing transparency as the transparency decreases gradually. The second preset function may be a monotonically increasing function.

$\begin{array}{cc}H=\max \left(0,\min \left(\frac{\mathrm{AS}}{\mathrm{IAS}·\mathrm{PR}},1\right)\right)& \left(2\right)\end{array}$

where H is the transparency, IAS is the initial transparency, i.e., the maximum transparency which may be 1, and PR is a configurable parameter.

Based on Formula (2), FIG. 8 is a schematic diagram of a relationship between the amplifying speed and the transparency as provided by the embodiments of the present disclosure, wherein the horizontal axis is the amplifying speed, and the vertical axis is the transparency. As seen from FIG. 8, the transparency gradually decreases as the amplifying speed decreases.

Optionally, after reducing the transparency of the particles based on the amplifying speed, the transparency of the particles may be randomly reduced to a preset transparency.

Wherein the preset transparency is a corresponding transparency when the particles dissipate. For example, the preset transparency may be 0.

Specifically, the above random reduce may be selecting a portion of particles from the first number of particles and reducing the transparency of this portion of particles to the preset transparency. In this way, the transparency can be gradually reduced based on the amplifying speed until the particles dissipate, and based thereon, a portion of particles may dissipate in advance, thereby further enriching the fireworks effect.
