Currently, the production process of this type of animation is relatively complicated and requires a lot of production costs.

[0004] In view of this, there is an urgent need in the art for an animation generation method that can save production costs and rendering power consumption, and achieve the purpose of flexibly adjusting rendering effects while generating a random light and dark change animation of a grid array.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] In the animation generation method of the example implementation mode of the present disclosure, the model face is divided into multiple blocks, and then the blocks are divided into grid areas and gap areas according to the distance from each pixel point in the block to the edge of the block.

[0029] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present disclosure will be more comprehensive and complete, and the concepts of the example embodiments are fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0030] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0031] In some related embodiments, for the random light and dark change animation of the grid array, since the texture animation of each grid area has a phase difference, the production process that can be used is as follows:

[0032] 1) Write a shader that supports periodic color changes in brightness and darkness. It needs to support loop playback with different periods and different start frames (that is, different periods and phases of brightness and darkness changes);

[0033] 2) Make a model of multiple quadrilaterals forming an array grid on the background color, which is used to render the entire array (this step can also be achieved using the particle system of some game engines, which is convenient for subsequent material random effect settings);

[0034] 3) For each quadrilateral, set different light and dark change start frames and appropriate change speeds to achieve the effect of random light and dark change animation;

[0035] 4) Provide a fixed background color environment, which can be the background color of the scene or another patch model as a substrate.

[0036] However, the process of generating the random light and dark change animation of the grid array in the above-mentioned related embodiments may involve the following problems:

[0037] 1) Each square in the array requires a quadrilateral, so the number of model faces is high;

[0038] 2) The spatial positions of the particles must be carefully arranged into an array, which will consume the workload of the art production staff;

[0039] 3) If there is no suitable particle system to automatically and randomly set material parameters, setting the material square by square will also consume a lot of energy of art production personnel.

[0040] Based on the above problems, this example implementation first provides an animation generation method, which is applied to the pixel shader stage. Figure 1 As shown, the above animation generation method may include the following steps:

[0041] Step S110: Divide the model face into a plurality of blocks according to a preset block density.

[0042] Step S120: Divide the block into a grid area and a gap area according to the distance from each pixel in the block to the edge of the block.

[0043] Step S130: Fill the gap area with a preset background color, and determine the real-time color corresponding to each square area at different time values ​​according to the random phase value, so as to generate a random light and dark change animation of the square array.

[0044] The animation generation method in the example implementation of the present disclosure can render a random light and dark change animation of a densely packed grid array without the need for textures or complex model production. On the one hand, the effect can be achieved with only one model face, avoiding the use of more model faces, and the size of the grids and gaps of the model can be arbitrarily divided according to parameters during rendering, thus avoiding the arrangement and size adjustment of complex model faces, thereby saving model production time and production costs; on the other hand, since no texture frame sampling is involved, the game package occupancy is reduced, the rendering video memory occupancy and sampling energy consumption are saved, thereby achieving the purpose of saving rendering power consumption; on the other hand, the various detail effects required by the solution can be easily achieved through parameter adjustment, thereby achieving the purpose of flexibly adjusting the rendering effect and saving the production and adjustment efforts related to various materials.

[0045] Next, combine Figures 2 to 6 The above steps of this exemplary embodiment are described in more detail.

[0046] In step S110, the model face is divided into a plurality of blocks according to a preset block density.

[0047] In this example implementation, the model UV can be block mapped according to the preset block density, so as to divide the model face into multiple blocks. The model UV can be multiplied according to the preset block density PatternDensity, and the calculation method is as follows:

[0048] float2 UVF=UV*PatternDensity

[0049] Among them, PatternDensity is a two-dimensional vector used to control the grid density in the horizontal and vertical directions. UV is the coordinate of each pixel point before blocking, and UVF is the coordinate of each pixel point after blocking.

[0050] For example, assuming that the model patch is divided into 4×4 blocks, then in order from left to right or from top to bottom, the UV coordinates of the pixels in the first block are 0 to 1, the UV coordinates of the pixels in the second block are 1 to 2, the UV coordinates of the pixels in the third block are 2 to 3, and the UV coordinates of the pixels in the fourth block are 3 to 4.

[0051] In step S120 , the block is divided into a grid area and a gap area according to the distance from each pixel in the block to the edge of the block.

[0052] For each block in the model patch, the block can be divided into a grid area in the middle of the block and a gap area around the grid area according to the distance from each pixel in the block to the edge of the block.

[0053] In this example implementation, Figure 2 As shown, according to the distance from each pixel point in the block to the edge of the block, the block is divided into a grid area and a gap area, which may specifically include the following steps:

[0054] Step S210: Obtain the second coordinate value of each pixel in the block according to the decimal part of the coordinate of each pixel in the block.

[0055] In this example implementation, the decimal part of the coordinates of each pixel point can be taken as the second coordinate value. The calculation method of the second coordinate value UV2 of the pixel point is as follows:

[0056] float2 UV2=frac(UVF)

[0057] The frac function represents taking the decimal part of a number, which is equivalent to mapping an independent horizontal and vertical linearly varying UV2 to each pixel of each block, and the second coordinate value UV2 of the pixel point is between 0 and 1. Using the independent horizontal and vertical linearly varying UV2 mapped by each block, the grid area and the gap area with light and dark changes can be divided.

[0058] Step S220: Calculate the distance field information from the pixel point to the edge of the block according to the second coordinate value of the pixel point.

[0059] In this example implementation, the absolute value of the coordinate difference between the pixel and the block center may be calculated based on the second coordinate value of the pixel, and then the distance field information from the pixel to the block edge may be calculated based on the absolute value of the coordinate difference between the pixel and the block center.

[0060] The absolute value UVDis of the UV difference from the pixel to the center of the block is calculated as follows:

[0061] float2 UVDis=abs(UV2–float2(0.5,0.5))

[0062] Among them, the abs function means taking the absolute value.

[0063] Then, the distance field information SDF from the pixel to the edge of the block is calculated using the absolute value UVDis of the coordinate difference between the pixel and the center of the block:

[0064] float SDF=max(UVDis.x,UVDis.y)*2

[0065] Among them, the max function is used to map the maximum values ​​of the above-mentioned horizontal and vertical values. Multiplying the horizontal and vertical coordinate values ​​by 2 can map the final result to 0 to 1, otherwise it is 0 to 0.5.

[0066] Step S230 : Generate a marking mask for distinguishing between a grid area and a gap area according to the distance field information, and divide the block into a grid area and a gap area according to the marking mask.

[0067] In this example implementation, a marking mask for distinguishing between a grid area and a gap area may be generated according to distance field information and a preset gap width, wherein the marking value of the marking mask in the gap area is a first marking value, and the marking value in the grid area is a second marking value.

[0068] Using the above distance field information SDF, we can calculate the marker mask latticeMask of the grid area and the gap area:

[0069] float latticeMask=step(SDF,1-gapWidth)

[0070] For the marker mask latticeMask, the value of this value in the gap area is the first marker value, for example, the value can be 0, and the value in the grid area is the second marker value, for example, the value can be 1. This value can be used as a marker to map the color of the gap and the grid. gapWidth is the preset gap width, which is used to control the width of the gap area. It can be set according to requirements. The value range of gapWidth is 0≤gapWidth≤1. The step function can be used to segment the image to achieve a certain gradient effect or simulate the lighting effect.

[0071] In this example implementation, the texture is divided into blocks, and then the distance from the pixels of each block to the edge of the block is calculated, so that the grid areas with varying brightness and the gap areas between the grids can be flexibly set.

[0072] In step S130, the gap area is filled with a preset background color, and the real-time color corresponding to each square area at different time values ​​is determined according to the random phase value, so as to generate a random light and dark change animation of the square array.

[0073] After dividing the gap area and grid area in each block, these two areas are filled with colors respectively, where the gap area is a fixed background color, and the grid area is filled with a color that changes light and dark over time, thereby generating a random light and dark change animation of the grid array.

[0074] In this example implementation, Figure 3 As shown, before determining the real-time color corresponding to each grid area at different time values ​​according to the random phase value, the following steps may also be included:

[0075] Step S310: Obtain the first coordinate value of each pixel point in the block according to the integer part of the coordinate of each pixel point in the block.

[0076] In this exemplary implementation, the integer part can be taken from the coordinates of each pixel point as the first coordinate value. The calculation method of the first coordinate value UV1 of the pixel point is as follows:

[0077] float2 UV1=floor(UVF)

[0078] The floor function represents rounding of numbers, that is, a uniform two-dimensional integer vector UV1 is mapped to each pixel in each block.

[0079] For example, assuming that the model patch is divided into 4×4 blocks, then in order from left to right or from top to bottom, the first coordinate value UV1 of the pixel points in the first block is 0, the first coordinate value UV1 of the pixel points in the second block is 1, and so on.

[0080] Step S320: Determine the random scalar value corresponding to the block according to the first coordinate value of each pixel point in the block.

[0081] The independent two-dimensional values ​​UV1 mapped from the above blocks are mapped again to a random scalar value rand, which is used for random control of the brightness and darkness of the grid. The calculation method of the random scalar value is as follows:

[0082] float rand=random01(UV1)

[0083] The random01 function represents randomly mapping a two-dimensional vector to a decimal rand between 0 and 1. There are many specific random mapping algorithms, which are not specifically limited in this example implementation.

[0084] Step S330: Determine the random phase value corresponding to the grid area in the block according to the random scalar value corresponding to the block.

[0085] The random scalar value rand can be used to obtain the random phase value corresponding to the grid area, and the color latticeColor that controls the real-time change of each grid can be mapped with the time value.

[0086] In this example implementation, Figure 4 As shown, the real-time color corresponding to each grid area at different time values ​​is determined according to the random phase value, which may specifically include the following steps:

[0087] Step S410: Obtain the color change function corresponding to the grid area according to the random phase value, and the preset grid color change rate and phase random degree parameters.

[0088] The color change function latticeChange corresponding to the grid area is calculated as follows:

[0089] float latticeChange=sin(changeSpeed*Time+rand*randAmount)

[0090] Among them, Time is the current running time of the program, the square color change rate changeSpeed ​​and the phase randomness parameter randAmount are pre-set values, changeSpeed ​​represents the speed of the change of the brightness of each block, and randAmount represents the randomness of the phase difference of the color change of each block (when this value is 0, the diffusion of each block is completely in phase). After the sine function sin calculation, the final result latticeChange is used to map the color of the square.

[0091] Step S420: Determine the real-time color corresponding to the grid area at different time values ​​according to the color change function corresponding to the grid area.

[0092] In this example implementation, the real-time colors of the grid area corresponding to different time values ​​may be determined according to the color change function corresponding to the grid area, and the preset first grid color value and second grid color value.

[0093] In this example implementation, latticeChange linear interpolation can be used to control the real-time changing lattice color latticeColor:

[0094] float3 latticeColor=lerp(latticeColorSet01,latticeColorSet02,latticeChange)

[0095] Among them, lerp is a linear interpolation function, latticeColorSet01 and latticeColorSet02 are the preset color values ​​of the first square and the second square, which represent the specific RGB colors of each square at the brightest and darkest moments respectively.

[0096] Finally, use the latticeMask information obtained above to distinguish the colors of the gaps and squares, and get the final color output output:

[0097] float3 output=lerp(gapColorSet,latticeColor,latticeMask)

[0098] Among them, the gap background color preset by gapColorSet represents the RGB color of the gap area.

[0099] In this example implementation, the gap areas of the grid are uniformly colored and the light and dark changes of the grid areas are mapped using time changes to generate a dynamic change effect. Random number mapping can also be used to create a time difference in the light and dark effects of each block to achieve a more random effect.

[0100] Figure 5 A schematic diagram of a random light and dark change animation of a grid array according to a specific embodiment of the present disclosure is shown, and the left and right figures respectively show the color display of the grid array corresponding to different moments.

[0101] Figure 6 A schematic diagram showing a random light and dark change animation of a grid array in another specific embodiment of the present disclosure is shown in FIG. Figure 5The schematic diagram after modifying the grid spacing parameters based on is shown on the left and right. The two figures on the left and right are the color displays of the grid array corresponding to different moments.

[0102] In this example implementation, after the shader of the above algorithm is loaded into the model material, the above parameters can be flexibly controlled in the application stage to adjust the final effect. The adjustable parameters are as follows:

[0103] 1) Use patternDensity to adjust the distribution density of the grid (that is, the size of each grid);

[0104] 2) Use gapWidth to control the relative size of the grid and the gap;

[0105] 3) Use latticeColorSet01 and latticeColorSet02 to control the brightest and darkest colors of each grid when the color changes;

[0106] 4) Use gapColorSet to control the color of the gaps between squares;

[0107] 5) Use changeSpeed ​​to control the speed of the grid color cycle;

[0108] 6) Use randAmount to control the size of the random phase difference of each square color cycle, that is, the degree of randomness of the change.

[0109] It should be noted that although the steps of the method in the present disclosure are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.
