CROSS-REFERENCE TO RELATED APPLICATIONS

The present disclosure claims priority of the Chinese Patent Application No. 202111210331.4, titled “SPECIAL EFFECT PROCESSING METHOD AND DEVICE” filed on Oct. 18, 2021, the contents of the application being incorporated herein by reference.

FIELD

Embodiments of the present disclosure relates to the technical field of computer processing, and more specifically, relates to an effect processing method, apparatus, electronic device, computer readable storage medium, computer program, and a computer program product.

BACKGROUND

Effect screens may be screens with special visual effects added to images, videos, texts, and so on. A typical effect screen may be composed of a large number of particles, each of which may be a unit of arbitrarily shape. Each particle is independent and is constantly moving and changing. Wherein, motion may be regular changes, or irregular changes, and the changes may be in colors, transparency, size, and so on. For example, by simulating fireworks with a large number of particles, the upward motion of a number of particles may simulate the rise of fireworks. Once the particles rise to a certain height and disappear, more particles are displayed at the location where the particles disappear, resulting in the effect of fireworks exploding.

It can be seen that the process of generating the above effect screen is a process of generating the particles, updating the particles, and rendering the particles. The more diverse the relationship between the particle quantity, particle color, particle size, and other factors included in the effect screen, the better the richness of the effect screen. Therefore, how to improve the rich performance of the effect screen becomes an urgent problem to be solved.

DETAILED DESCRIPTION OF EMBODIMENTS

In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of this disclosure.

The embodiments of the present disclosure may be applied to the process of simulating effect screens through particles. FIG. 1 is a schematic diagram of an effect screen that simulates an explosion effect of fireworks through particles, wherein a particle may be constituted of one or more adjacent pixels. Of course, the effect screen that may be simulated through particles may include but are not limited to: cloud effect, volcanic eruption effect, and flame effect.

In order to realize the effect screen, it may be carried out through an electronic device, which is equipped with a processor that may perform a large number of computation and a screen that may display particles. The processor may be a central processing unit (CPU) or a graphic processing unit (GPU).

Since effect screens are formed by the motion of a large number of particles, the processor requires powerful computing capabilities. And because the GPU has better parallel computing capabilities than the CPU, using the GPU to simulate effect screens may effectively improve the computing performance of particles.

In the prior art, when simulating effect screens through the GPU, a fixed method is used to update the attributes of particles, resulting in poor diversity of effect screens.

In order to solve the above problem, the embodiment of the present disclosure may adjust the motion attribute of particles through the target motion attributes of at least two positions in the target image, so that the particles move according to the adjusted motion attributes to form an effect screen with a target shape. That is, the shape of an effect screen finally displayed can be specified by means of a target image, and different shapes of effect screens can be achieved by means of different target images, such that the richness of the effect screens is improved.

The technical solutions of the embodiment of the present disclosure and how the technical solutions of the present disclosure solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiment of the present disclosure will be described below with reference to the drawings.

FIG. 2 is a step flowchart of an effect processing method provided by embodiments of the present disclosure. The method shown in FIG. 2 may be applied in an electronic device. Referring to FIG. 2, the effect processing method comprises:

S101: obtain a target image, the target image comprising target motion attributes of at least two positions, target motion attributes of each position being used for forming particles into a target shape after motion.

Wherein the target image is any image including target motion attributes. A commonly used target image may be a signed distance function (SDF) graph, also known as a texture graph. The SDF is a function between two vectors, which means that the input is a vector and the output is also a vector. The SDF graph may be three-dimensional or two-dimensional. The three-dimensional SDF graph may be represented by a vector field. All points in the three-dimensional SDF graph tend to another three-dimensional vector. The embodiment of the present disclosure may drive particles to move toward a target area through the three-dimensional vector, and finally form a target shape in the target area.

Based on the above description, it can be understood that the above target motion attribute may be represented by a vector. For example, the target motion attribute may be a three-dimensional vector, causing the particles move in a three-dimensional space, and the final formed target shape is also a shape in a three-dimensional space.

The target motion attribute may be speed, acceleration, position, etc., which are not limited in the embodiment of the present disclosure.

The target image may be obtained by converting the target model. Specifically, first, obtain a target model corresponding to the target shape, the target model comprising at least two points; then, converting the position of each point in the target model to the target motion attribute of the position in the target image.

Wherein the target model is a model composed of at least two points, and these points constitute the target shape. It can be understood that the position of each point in the target model is a vector, which may be called a position vector. Performing linear or nonlinear transformation to the position vector may obtain the target motion attributes of that position.

In the prior art, there are tools such as blender, houdini, unity, etc. that can convert target models to SDF graphs, so these tools may be used directly to obtain SDF graphs.

S102: during motion process of at least two particles, adjust the motion attribute of the particles at the current position according to target motion attributes corresponding to the current position of the particles in the target image, the adjustment being used for reducing a difference between the motion attribute and the target motion attribute.

Wherein particles are randomly generated, that is, when generating particles, position, color, size, maximum display duration and other attributes of the particles are set randomly. After the particles are generated, the effect screen of the particles in their initial state may be displayed.

After the particles are generated, motion attributes of the particles at the current position may be updated to make the particles move. Therefore, the motion attributes of particles are different at different positions.

The target motion attribute relied upon by the adjustments is determined based on the current position. The target motion attribute corresponding to the current position in the target image is the target motion attribute of the position closest to the current position in the target image. In an ideal state, the position closest to the current position is the current position.

In the embodiment of the present disclosure, the adjusted motion attribute may be obtained in two ways.

In a first way, the target motion attribute and the motion attribute to be adjusted are weighted to obtain the adjusted motion attribute. Assuming the motion attribute is an I-dimensional vector, the adjusted motion attribute may be calculated through the following formula:

${\mathrm{AV}}_i=p1·V{1}_i+p2·V{2}_i$

Wherein AV_i is the value of the i-th dimension of the adjusted motion attribute, V1_i is the value of the i-th dimension of the motion attribute before adjustment, V2_i is the value of the i-th dimension of the target motion attribute, p1 is the weighting coefficient of V1_i, and p2 is the weighting coefficient of V2_i.

Of course, the weighting coefficients need to meet the preset conditions so that the adjusted motion attribute is closer to the target motion attribute than the motion attribute before adjustment. Both the p1 and p2 are larger than 0, and p1+p2=1.

In a second way, first, the vector difference between the target motion attribute and the motion attribute before adjustment is determined; then, the adjustment amount is determined based on the vector difference and the preset coefficient; finally, the adjusted motion attribute is determined based on the sum of the adjustment amount and the motion attribute before adjustment.

Wherein, the adjustment amount may be the product of the vector difference and a preset coefficient, and the preset coefficient is a value greater than 0 and less than 1. For example, the preset coefficient may be 0.2, so that each adjustment may reduce the difference between the motion attribute and the target motion attribute by 20%.

It should be noted that when the preset coefficient is set to a larger value, fewer adjustments are required to form the target shape. That is, the target shape is formed in a shorter time, but the continuity between different positions is poor, and the process of forming the target shape would not be clear enough. When the preset coefficient is set to a smaller value, more adjustments are required to form the target shape. That is, the target shape is formed in a longer time, but the continuity between different positions is better, and the process of forming the target shape is clearer.

In order to accurately control the target shape finally formed by the particles, the embodiments of the present disclosure control the target shape through a geometry, including the position and size of the target shape, that is, the target shape is located in the geometry.

In addition, it can be seen from the above description that the at least two particles are randomly generated, and their positions are represented by coordinates in the world coordinate system. That is, the afore-mentioned current position is the position in the world coordinate system. Therefore, in order to achieve the above-mentioned control of the target shape, when adjusting the motion attribute of the particles at the current position according to the target motion attribute corresponding to the current position of the particles in the target image, it needs to be adjusted according to the following process: first, converting the current position of the particle in the world coordinate system to the second position of the particle in the geometry; then, according to the target motion attribute corresponding to the second position of the particles in the target image, adjusting the motion attribute of the particles at the current position.

Wherein the target motion attribute corresponding to the second position of the particle in the target image is the target motion attribute of the position closest to the second position in the target image. In an ideal state, the position closest to the second position is the second position.

The target shape may be any shape located in the geometry, and the size of the target shape can be less than or equal to the size of the geometry.

Alternatively, the target shape may be an inscribed shape of the geometry, so that the size of the target shape is as close as possible to the size of the geometry, which also ensures that the size of the final formed target shape is consistent with the size of the preset geometry, achieving accurate control of the size of the effect screen.

The geometry may be any geometry, for example, a cuboid, a cube, a cylinder, a cone, a sphere, etc. The embodiments of the present disclosure do not limit the shape of the geometry.

In order to achieve a more flexible effect screen, in the embodiments of the present disclosure, the size of the geometry, position of the geometry, and rotation angle of the geometry relative to the world coordinate system are not limited. That is, the geometry may not be located at the origin of the world coordinate system, and the geometry may have an angle with the world coordinate system.

FIG. 3 is a schematic diagram of the relationship between a cuboid and a world coordinate system provided by embodiments of the disclosure. Referring to FIG. 3, there is no rotation angle between the cuboid and the world coordinate system. One vertex of the cuboid is the origin of the world coordinate system, and the three sides of the cuboid coincide with the coordinate axes of the world coordinate system, respectively. At this time, the position in the cuboid is the position in the world coordinate system, and there is no need to convert the position in the world coordinate system.

On the contrary, when there is a rotation angle between the cuboid and the world coordinate system, and/or the vertex of the cuboid is not the origin of the world coordinate system, and/or, when at least one of the three sides of a vertex of the cuboid does not coincide with the coordinate axis of the world coordinate system, the position in the cuboid is not the position in the world coordinate system, and the position in the world coordinate system needs to be converted to the position in the cuboid.

FIG. 4 is a schematic diagram of another relationship between a cuboid and a world coordinate system provided by embodiments of the disclosure. Referring to FIG. 4, there is an angle between the cuboid and the world coordinate system. The vertex of the cuboid is not the origin of the world coordinate system, and the three sides of any vertex of the cuboid do not coincide with the coordinate axis of the world coordinate system. At this time, the position in the world coordinate system needs to be converted to a position in the cuboid.

Optionally, converting the current position of the particle in the world coordinate system to the second position of the particle in the geometry, may comprise: converting the current position of the particles in the world coordinate system to the second position of the particles in the geometry according to attributes of the geometry, wherein the attributes of the geometry comprise at least one of the following: size of the geometry, center position of the geometry, and the angle of the geometry relative to the world coordinate system.

The process of determining the second location based on the attributes may include the following processes:

First, construct four matrices S, T, R and L.

When the geometry is a cuboid, the dimensions of the geometry include the length, width, and height of the cuboid, so the following matrix S can be constructed from the length, width, and height:

$S=\left[\begin{array}{cccc}{S}_1& 0& 0& 0\\ 0& S_2& 0& 0\\ 0& 0& S_3& 0\\ 0& 0& 0& 1\end{array}\right]$

Wherein, S₁ is the reciprocal of length, S₂ is the reciprocal of width, and S₃ is the reciprocal of height.

Construct the following matrix T based on the center position of the geometry:

$T=\left[\begin{array}{cccc}1& 0& 0& T_x\\ 0& 1& 0& T_z\\ 0& 0& 1& T_y\\ 0& 0& 0& 1\end{array}\right]$

Wherein T_x, T_y, and T_z are respectively the x coordinate, y coordinate, and z coordinate of the center position of the geometry.

According to the angles α, β and γ between the geometry and the three planes YOZ, XOZ and XOY respectively, the following matrix R is constructed:

$T=\left[\begin{array}{cccc}\cos \gamma \cos \beta & -s\mathrm{in}\gamma \cos \alpha +\cos \gamma \sin \beta \sin \alpha & \sin \gamma \sin \alpha +\cos \gamma \sin \beta \cos \alpha & 0\\ \sin \gamma \cos \beta & \cos \gamma \cos \alpha +\sin \gamma \sin \beta \sin \alpha & -\cos \gamma \sin \alpha +\sin \gamma \sin \beta \cos \alpha & 0\\ -\sin \beta & \cos \beta \sin \alpha & \cos \beta \cos \alpha & 0\\ 0& 0& 0& 1\end{array}\right]$

Construct the following matrix L based on the current position of the particles in the world coordinate system:

$L=[\begin{array}{cccc}{L}_x& L_y& L_z& 1]\end{array}$

Wherein L_x, L_y, and L_z are the x coordinate, y coordinate, and z coordinate of the current position, respectively.

Then, calculate the product of the above four matrices to obtain the target matrix L2=S·R·T·L. It can be seen that L2 is a 1*4 matrix.

Finally, use the first three columns in L2 as the x coordinate, y coordinate, and z coordinate of the second position in the geometry.

After the second position is obtained, the motion attribute may be adjusted, and the adjustment may include two ways:

In a first way, according to the target motion attribute corresponding to the second position in the target image, the motion attribute of the particles at the current position may be adjusted. Same as the process of adjusting the motion attribute of particles at the current position based on the target motion attribute corresponding to the current position in the target image, the adjusted motion attribute is also determined based on the target motion attribute and the motion attributes before adjustment. The process of determining the adjusted motion attribute may refer to the foregoing detailed description, and will not be described again here.

In a second way, first, the second position is normalized to obtain a third position, each coordinate of the third position being greater than or equal to 0 and less than or equal to 1; then, according to the target motion attribute corresponding to the third position of each particles in the target image, performing the above adjustment to the motion attribute of the particles at the current position.

Wherein the target motion attribute corresponding to the third position in the target image is the target motion attribute of the position closest to the third position in the target image. In an ideal state, the position closest to the third position is the third position.

Same as the process of adjusting the motion attribute of particles at the current position based on the target motion attribute corresponding to the current position in the target image, according to the target motion attribute corresponding to the third position in the target image, the above adjustment is made to the motion attribute of the particles at the current position, that is, the adjusted motion attribute is also determined based on the target motion attribute and the motion attribute before adjustment. The process of determining the adjusted motion attribute may refer to the foregoing detailed description, and will not be described again here.

The embodiments of the present disclosure can implement a cyclic adjustment process of motion attributes, so that every time a particle reaches a position, the motion attributes of the particles at that position are updated until the at least two particles form a target shape. In this way, different positions can have different motion attributes. FIG. 5 is a schematic diagram of a cyclic adjustment process of motion attributes provided by embodiments of the present disclosure. Referring to FIG. 5, after each execution of S102, the current position of the particles is updated according to the adjusted motion attribute, and S102 is executed again.

Wherein the algorithm for updating the current position is related to motion attributes. For example, when the motion attribute is the motion speed of particles, first, determine the motion distance based on the motion speed and update duration; then, the updated current position is determined based on the motion distance and the current position before the update.

S103: display the particles according to the adjusted motion attribute to obtain an effect screen, the particles being geometric display objects.

Wherein the display object is displayed on one or more pixels, and these pixels constitute the geometric shape. The position, color, brightness, etc. of these pixels may change over time.

Specifically, the particles are displayed after each motion attribute is adjusted, that is, the vertex/pixel shader is called to render the particles to obtain an effect screen. In this way, effect screens are formed by the continuous motion of particles.

Wherein when rendering particles, the vertex/pixel shader may call geometric shapes to render particles, so as to render particles of different geometric shapes. The geometric shape may include, but is not limited to: a point, a line, a face, and a cube. Wherein the face may be a square, a triangle, a strip, a grid, etc. The embodiments of the present disclosure do not limit the geometric shape of the particles.

It should be noted that the pixels constituting the particles may be adjacent or non-adjacent.

It can be seen from the foregoing description of the embodiments of the present disclosure that, the motion attributes of particles, the position in the target image, the target motion attributes, and the current position of the particles used in the embodiments of the present disclosure are all three-dimensional, and the target model is a three-dimensional model, so the generated effect screen is also three-dimensional. In this way, the embodiments of the present disclosure can further improve the richness of effect screens.

Of course, in practical applications, the target model may also be a two-dimensional model, and the target motion attributes, positions, and motion attributes of the particles are all two-dimensional vectors, so that the effect screen generated in this way is two-dimensional. The embodiments of the present disclosure do not make limitations on this.
