Description

Technical Field

[0001] This invention relates to the field of animation generation technology, and in particular to a method, apparatus, electronic device, and storage medium for generating beam animation. Background Technology

[0002] Beam animation effects are common animation effects. For example, in virtual games, volumetric light based on the Tyndall effect is a beam effect with a strong sense of atmosphere, which can enhance the experience and realism of virtual games.

[0003] In existing technologies, beam animation effects are typically achieved by constructing a 3D space on the screen for volumetric lighting rendering. This requires an additional camera and sampling of numerous textures to achieve different beam effects. For animation scenes that do not require rotating the viewpoint, this approach suffers from the technical problem of wasting rendering resources. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a method, apparatus, electronic device and storage medium for generating beam animation, so as to reduce the waste of rendering resources.

[0005] In a first aspect, embodiments of the present invention provide a method for generating beam animation, the method comprising: creating a patch model; performing polar coordinate transformation on the initial texture coordinate data of the patch model to obtain target polar coordinate data; performing frame-by-frame superposition of the target polar coordinate data with time offset variables to obtain sampling coordinate data corresponding to each frame; sampling a preset base map frame-by-frame using the sampling coordinate data corresponding to each frame to obtain a target sampling result corresponding to each frame; sampling a preset mask map to obtain a mask sampling result; and superimposing the mask sampling result with the target sampling result corresponding to each frame to obtain a target planar beam animation.

[0006] Secondly, embodiments of the present invention provide a beam animation generation apparatus, the apparatus comprising: a construction module for creating a patch model, performing polar coordinate transformation on the initial texture coordinate data of the patch model to obtain target polar coordinate data; a sampling module for performing frame-by-frame superposition of the target polar coordinate data with time offset variables to obtain sampling coordinate data corresponding to each frame, and performing frame-by-frame sampling on a preset base map using the sampling coordinate data corresponding to each frame to obtain a target sampling result corresponding to each frame; and a masking module for sampling a preset mask map to obtain a masking sampling result, and superimposing the masking sampling result with the target sampling result corresponding to each frame to obtain a target planar beam animation.

[0007] Thirdly, embodiments of the present invention provide an electronic device, including a processor and a memory, wherein the memory stores machine-executable instructions that can be executed by the processor, and the processor executes the machine-executable instructions to implement the above-described method for generating beam animation.

[0008] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing computer-executable instructions. When the computer-executable instructions are invoked and executed by a processor, the computer-executable instructions cause the processor to implement the above-described method for generating beam animation.

[0009] The embodiments of the present invention bring the following beneficial effects:

[0010] The aforementioned method, apparatus, electronic device, and storage medium for generating beam animation involve creating a patch model, performing polar coordinate transformation on the initial texture coordinate data of the patch model to obtain target polar coordinate data, performing frame-by-frame superposition of the target polar coordinate data with a time offset variable to obtain sampling coordinate data corresponding to each frame, sampling a preset base map frame-by-frame using the sampling coordinate data corresponding to each frame to obtain the target sampling result corresponding to each frame, sampling a preset mask map to obtain a mask sampling result, and superimposing the mask sampling result with the target sampling result corresponding to each frame to obtain the target planar beam animation. In this method, using the patch model as the carrier and rendering object of the beam animation avoids the waste of rendering resources caused by rendering beam animation based on the camera in the scene. By performing polar coordinate transformation on the initial texture coordinate data of the patch model and then performing frame-by-frame superposition sampling with a time offset variable, dynamic sampling results can be generated. Then, by masking the sampling results with a mask map, dynamic target planar beam animation within the masked area can be obtained, thus quickly obtaining planar beam animation without rotating the viewpoint and reducing the waste of rendering resources.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” or “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the method for generating beam animation in this invention includes:

[0028] Step S10: Create a patch model, perform polar coordinate transformation on the initial texture coordinate data of the patch model to obtain the target polar coordinate data;

[0029] It is understandable that a patch refers to a local tangent plane on the surface of a 3D object, which can approximate the surface of a 3D object within a certain local area. A patch model is essentially a shape in 3D space, such as a rectangle, which possesses the properties of a 3D model and can be used for material rendering. In this embodiment, the patch model serves as the carrier of the beam material and is the object of beam effect rendering; the final target plane beam animation is displayed in the patch model. In one embodiment, the patch model is created using a game engine (such as Unity or Unreal Engine) or Digital Content Creation (DCC) software (such as 3ds Max or Maya), and initial texture coordinate data (also known as initial UV coordinate data) of the patch model is generated. It is understandable that the created patch model can be a blank material model, that is, a solid color or colorless model without a texture bound, or a default material model, a model bound to a default texture. Whether it is a blank material model or a default material model, it has corresponding initial UV coordinate data, which is obtained by performing a UV unwrapping operation on the patch model. This UV coordinate data is used to sample the preset base texture after subsequent conversion processing.

[0030] In one implementation, to improve the efficiency of beam animation rendering in the game and reduce the waste of rendering resources, a UI (User Interface) element is created using the canvas component in the game engine. This UI element can then be used to indicate the patch model. Since the canvas component includes a camera-free rendering mode, the UI element created using the canvas component is particularly suitable for rendering beam effects that do not require changing the viewpoint, consuming low rendering resources and not degrading the rendering quality. In one implementation, when creating the UI element using the canvas component, a material shader can be specified, and subsequent steps S20-S30 can be executed using the specified material shader to complete the custom rendering of the beam effect and obtain the target plane beam animation.

[0031] It is understandable that the initial UV coordinate data of the patch model is in a Cartesian coordinate system. To achieve the divergence and rotation effects of the light beam, the initial UV coordinate data is converted to polar coordinates to obtain the target polar coordinate data. The polar coordinate system consists of a pole, a polar axis, and a polar radius. The position of any point in the polar coordinate system is represented by the length of the line segment between the pole and that point (i.e., the polar radius), and the angle between the polar radius and the polar axis. In one implementation, based on the transformation relationship between the Cartesian and polar coordinate systems, the initial texture coordinates of the patch model are transformed to polar coordinates to obtain the target polar coordinate data. From the above principle, assuming any point in the Cartesian coordinate system is A(x,y), and this point is represented in the polar coordinate system as A(ρ,θ), then the following transformation relationship exists between the Cartesian and polar coordinate systems:

[0032]

[0033]

[0034] Where x refers to the x-coordinate value of any point in the initial texture coordinate data, y refers to the y-coordinate value of that point in the initial texture coordinate data, ρ refers to the polar radius of that point in the target polar coordinate data, and θ refers to the polar angle of that point in the target polar coordinate data.

[0035] Understandably, if the texture is sampled based on the target polar coordinate data, the obtained sampling result will show the texture as rotated or radial. Therefore, by performing polar coordinate transformation, the sampling coordinate data of the rotation or radial effect can be obtained quickly, thereby improving the generation efficiency of beam animation.

[0036] In one implementation, by changing the value range of the initial texture coordinate data, or by performing a polar coordinate transformation on the initial texture coordinate data of the face model to obtain first polar coordinate data, different target polar coordinate data can be obtained by changing the value range of the first polar coordinate data. The sampling results using these different target polar coordinate data will affect the position of the beam divergence center in the final target plane beam animation, thereby achieving beam animation effects with different beam divergence centers and improving the flexibility of beam animation generation. For example, Figure 2 As one effect of the preset base map, if the value range of the initial texture coordinate data or the value range of the first polar coordinate data is not changed, the preset base map is sampled using the obtained target polar coordinate data, and the resulting sampling result is as follows. Figure 3 As shown, the sampling result corresponds to the beam divergence center of the final target plane beam animation located at the upper left corner of the image. However, if the value range of the initial texture coordinate data or the value range of the first polar coordinate data is changed, the obtained sampling result can be as follows: Figure 4As shown, the sampling result corresponds to the beam divergence center of the final target plane beam animation located at the center of the image, but the specific location is not limited here.

[0037] In one implementation, before performing polar coordinate transformation on the initial texture coordinate data of the face model, the initial texture coordinate data can be offset by a preset value to obtain target texture coordinate data. Then, the target texture coordinate data is transformed into polar coordinates to obtain target polar coordinate data. It can be understood that by offsetting the initial texture coordinate data by a preset offset value, the beam divergence center of the final target planar beam animation can be moved outside the frame. For example, as... Figure 5 As shown, a sampling result is obtained by sampling a preset base map using target polar coordinate data generated by offsetting the initial texture coordinate data by a preset value. Figure 5 Compared to Figure 3 The beam divergence center moves outside the screen. Different preset offset values ​​can change the position of the beam divergence center outside the screen, but the specifics are not limited here.

[0038] Step S20: Superimpose the time offset variable on the target polar coordinate data frame by frame to obtain the sampling coordinate data corresponding to each frame. Then, sample the preset base map frame by frame using the sampling coordinate data corresponding to each frame to obtain the target sampling result corresponding to each frame.

[0039] In this embodiment, to enhance the dynamic beam flow effect and generate beam animation, the sampling coordinates of each frame are offset by a time offset variable, resulting in different sampling coordinate data for each frame. It can be understood that the time offset variable increases with the progression of time in each frame; for example, the time offset variable is 0 for the first frame, 20 for the second frame, and 40 for the third frame, but the specifics are not limited here. In this embodiment, the time offset variable for each frame is first determined, and then the target polar coordinate data is superimposed with the time offset variable for each frame to obtain the corresponding sampling coordinate data for each frame. Since the time offset variable increases with the progression of time in each frame, the sampling coordinate data for each frame also increases with the progression of time in each frame, thus producing the beam flow animation effect. It should be noted that, since the sampling coordinate data increases with the progression of time in each frame, in order to perform cyclic sampling and avoid the use of coordinate data that cannot correspond to the coordinates of the preset base map, the sampler's addressing mode is a cyclic mode. That is, if the sampling coordinate data exceeds the coordinate range of the preset base map, the sampling coordinate data is re-determined through the cyclic addressing mode to obtain sampling coordinate data that conforms to the coordinate range. For example, assuming that a sampled coordinate data of 1.2 is obtained by superimposing time offset variables, which exceeds the coordinate range of [0,1] of the preset base map, then 1.2-1=0.2 can be used to obtain the sampled coordinate data of 0.2 within the map coordinate range. The specific value is not limited here.

[0040] In one implementation, the frame-by-frame superposition of the time offset variable on the target polar coordinate data can be either a single-direction superposition or a multi-directional superposition. Specifically, in a single-direction superposition implementation, the frame-by-frame superposition of the time offset variable on the target polar coordinate data to obtain the sampled coordinate data corresponding to each frame includes: determining the time offset variable for each frame, and superimposing the polar radius in the target polar coordinate data with the time offset variable for each frame to obtain the sampled coordinate data corresponding to each frame. In a multi-directional superposition implementation, the frame-by-frame superposition of the time offset variable on the target polar coordinate data to obtain the sampled coordinate data corresponding to each frame includes: determining the time offset variable for each frame, superimposing the polar radius in the target polar coordinate data with the time offset variable for each frame, and superimposing the polar radius in the target polar coordinate data with a preset offset angle to obtain the sampled coordinate data corresponding to each frame.

[0041] In this embodiment, after obtaining the sampling coordinate data corresponding to each frame, the preset base map is sampled frame by frame using a preset sampler to obtain the target sampling result corresponding to each frame. In one embodiment, the frame rate per second (fps) of the target plane beam animation can be preset or dynamically determined according to rendering resources. That is, in this step, the frame rate per second of the target polar coordinate data obtained by superimposing the time offset variable frame by frame can be preset or dynamically determined according to rendering resources. For example, assuming the preset fps is 24 frames / second, then when superimposing the time offset variable frame by frame on the target polar coordinate data, 24 frames of time offset variable are superimposed per second to obtain the sampling coordinate data corresponding to 24 frames per second. In real-time rendering in the game engine, the frame rate per second can be determined in real time according to the rendering resources during real-time rendering, such as network speed and hardware configuration of the rendering terminal. The specific details are not limited here.

[0042] Step S30: Sample the preset mask texture to obtain the mask sampling result, and superimpose the mask sampling result with the target sampling result corresponding to each frame to obtain the target plane beam animation.

[0043] It is understandable that the target plane beam animation is a Tyndall effect animation on a 2D plane. To obtain better beam animation effects and make the beam range of the target plane beam animation more controllable, a preset mask map is sampled, and the obtained mask sampling results are superimposed with the target sampling results corresponding to each frame. This limits the beam range and beam intensity of the target plane beam animation to the specified standards of the preset mask map, thereby generating beam animations with different effects more flexibly. For example... Figure 6 The image shown is one implementation of a preset mask texture, based on... Figure 6 One frame of the target plane beam animation generated by the preset mask map can be as follows: Figure 7 As shown, it can be seen Figure 7 The beam range is limited to the white area of ​​the preset mask map. Without the sampling and overlay of the preset mask map, the beam range of the target plane beam animation will exist in the entire screen. Therefore, the preset mask map achieves the effect of beam masking, making the beam animation effect more controllable and the generation method more flexible.

[0044] The beam animation generation method provided by the above embodiments uses a patch model as the carrier and rendering object of the beam animation, which can avoid the waste of rendering resources caused by rendering beam animation based on the camera in the scene. By performing polar coordinate transformation on the initial texture coordinate data of the patch model and then performing frame-by-frame superposition sampling of the time offset variable, dynamic sampling results can be generated. Then, by masking the sampling results with a mask map, dynamic target planar beam animation within the mask range can be obtained, thereby quickly obtaining planar beam animation without rotating the viewpoint and reducing the waste of rendering resources.

[0045] Please see Figure 8 Another embodiment of the method for generating beam animation in this invention includes:

[0046] Step S801: Create a patch model, perform polar coordinate transformation on the initial texture coordinate data of the patch model to obtain the target polar coordinate data;

[0047] In one embodiment, step S801 includes: creating a patch model using a preset canvas component, the patch model being a quadrilateral patch model; performing a polar coordinate transformation on the initial texture coordinate data of the patch model using a preset pole to obtain initial polar coordinate data, the preset pole being used to indicate the target beam divergence center; and performing a fixed-value offset on the initial polar coordinate data to obtain target polar coordinate data. In this embodiment, to improve the rendering efficiency of the beam animation, unlike the volume rendering method using a scene as the carrier, this embodiment uses a patch model as the carrier for the beam animation. Initial texture coordinate data is generated using a quadrilateral patch model created using a preset canvas component, and then the initial texture coordinate data is transformed on a polar coordinate using a preset pole to obtain initial polar coordinate data. The preset pole is used to indicate the target beam divergence center in the target planar beam animation; that is, different preset poles can produce target planar beam animations with different beam divergence centers. Next, by applying a fixed-value offset to the initial polar coordinate data, the target beam divergence center can be moved out of the target plane beam animation's frame range, that is, out of the plane model's frame range, achieving the effect that there is more than one beam divergence center in the frame, making the beam animation more realistic.

[0048] In one embodiment, the above-mentioned polar coordinate transformation of the initial texture coordinate data of the face model to obtain initial polar coordinate data includes: constructing polar coordinates of the initial texture coordinate data of the face model to a preset pole using a preset arctangent function. In this embodiment, the preset arctangent function can quickly construct polar coordinates of the initial texture coordinate data of the face model to a preset pole, thereby obtaining initial polar coordinate data. The arctangent function is one of the inverse trigonometric functions, referring to the inverse function of y = tanx.

[0049] Step S802: Determine the first time offset variable and the second time offset variable for each frame. The second time offset variable is greater than the first time offset variable. The second time offset variable and the first time offset variable increase as time progresses.

[0050] In this embodiment, to enhance the rolling flow effect of the beam animation, two sampling results of different beam flow velocities are obtained using two different time offset variables. These two sampling results are then superimposed to achieve the rolling beam flow effect. In this embodiment, both the first and second time offset variables increase with time and frame count, and the second time offset variable is greater than the first time offset variable. For example, assuming the first time offset variable is 0 in the first frame, then the second time offset variable in the first frame could be 0.21, the first time offset variable in the second frame could be 0.2, and the second time offset variable in the first frame could be 0.41; specific values ​​are not limited here. In one embodiment, the difference between the first and second time offset variables can be a fixed preset difference or a dynamically changing dynamic difference; specific values ​​are not limited here.

[0051] In one implementation, determining a first time offset variable and a second time offset variable for each frame includes: determining a first time offset constant, a second time offset constant, and a time variable value for each frame; superimposing the time variable value and the first time offset constant for each frame to obtain the first time offset variable for each frame; and superimposing the time variable value and the second time offset constant for each frame to obtain the second time offset variable for each frame. In this implementation, to make the rolling speed of the beam flow controllable, the first time offset constant and the second time offset constant indicate the beam rolling speed. Specifically, in this implementation, the first time offset variable for each frame is obtained by superimposing the time variable value and the first time offset constant for each frame, and the second time offset variable for each frame is obtained by superimposing the time variable value and the second time offset constant for each frame. The first and second time offset constants are fixed constants, while the time variables are variables that increase with time and the time progression of each frame, such as 0 for the first frame, 20 for the second frame, 40 for the third frame, and so on. Specific values ​​are not limited here. Assuming the first time offset constant is 0.01 and the second time offset constant is 0.02, then the first time offset variable of the first frame is 0.01 (i.e., 0 + 0.01 = 0.01), the second time offset variable of the first frame is 0.02 (i.e., 0 + 0.02 = 0.02), the first time offset variable of the second frame is 20.01 (i.e., 20 + 0.01 = 20.01), and the second time offset variable of the second frame is 20.02 (i.e., 20 + 0.02 = 20.02). The specific values ​​are not limited here.

[0052] Step S803: Frame by frame superposition of the first time offset variable on the target polar coordinate data to obtain the first sampled coordinate data corresponding to each frame; Frame by frame superposition of the second time offset variable on the target polar coordinate data to obtain the second sampled coordinate data corresponding to each frame.

[0053] In this step, the target polar coordinate data is superimposed using the first time offset variable of each frame to obtain the first sampled coordinate data for each frame. Then, the target polar coordinate data is superimposed using the second time offset variable of each frame to obtain the second sampled coordinate data for each frame. Different time offset variables indicate different sampled coordinates, thus obtaining different sampling results. For example, if a coordinate in the target polar coordinate data is 10, and the first time offset variable in the first frame is 0.01, then the first sampled coordinate data for the first frame is 10.01. If the first time offset variable in the second frame is 20.01, then the first sampled coordinate data for that coordinate in the second frame is 30.02 (i.e., 10.01 + 20.01 = 30.02). The specific value is not limited here. The second sampled coordinate data follows the same principle, and will not be elaborated further here.

[0054] Step S804: Sample the preset base texture frame by frame using the first sampling coordinate data corresponding to each frame to obtain the first sampling result corresponding to each frame; sample the preset base texture frame by frame using the second sampling coordinate data corresponding to each frame to obtain the second sampling result corresponding to each frame.

[0055] In this step, different sampling coordinate data for each frame are used to sample the preset base map, resulting in different sampling results for each frame. This achieves the beam rolling effect generated by the superposition of different sampling results. For example, assuming a first sampling coordinate data of 10.01 in the first frame, then the pixel in the first sampling result of the first frame originates from the pixel at coordinate 10.01 in the preset base map. Specific details are not specified here. The second sampling result follows the same principle, and will not be elaborated further here.

[0056] In one embodiment, the preset base map contains multiple black and white stripes, with a grayscale gradient transition between each stripe. In this embodiment, to improve the efficiency of base map creation and reduce the complexity of texture creation, the preset base map contains multiple black and white stripes, with a grayscale gradient transition between each stripe, which can be used to create beam effects. For example... Figure 2 As shown, the width of each bar indicates the thickness of the beam in the target plane beam animation, the distance between each bar indicates the distance between the beams in the target plane beam animation, and the brightness of the preset base map indicates the brightness of the beam in the target plane beam animation, making the beam animation effect generation more flexible.

[0057] Step S805: Superimpose the first sampling result and the second sampling result corresponding to each frame to obtain the target sampling result corresponding to each frame;

[0058] In this step, the first and second sampling results corresponding to each frame are superimposed to obtain the target sampling result corresponding to each frame. All target sampling results are played frame by frame to achieve the effect of beam animation.

[0059] Step S806: Sample the preset mask texture to obtain the mask sampling result, and superimpose the mask sampling result with the target sampling result corresponding to each frame to obtain the target plane beam animation.

[0060] In one embodiment, step S806 includes: sampling a preset mask map to obtain a mask sampling result; calculating a gradient grayscale with attenuation based on the mask sampling result to obtain a gradient grayscale result; and superimposing the mask sampling result and the gradient grayscale result with the target sampling result corresponding to each frame frame by frame to obtain a target planar beam animation. In this embodiment, by calculating the gradient grayscale with attenuation, the masking intensity of the preset mask map on the target sampling result corresponding to each frame can be indicated. In one embodiment, the gradient grayscale result is obtained by calculating the attenuation grayscale of the mask sampling result using a preset attenuation function. Since the preset mask map has a gradient effect, the attenuation grayscale also has a gradient effect. Finally, the mask sampling result, the gradient grayscale result, and the target sampling result corresponding to each frame are superimposed frame by frame to obtain the mask sampling result corresponding to each frame. Then, all the mask sampling results are played frame by frame to obtain the target planar beam animation.

[0061] In one embodiment, the above-mentioned calculation of the attenuated gradient grayscale based on the mask sampling results to obtain the gradient grayscale result includes: calculating the attenuated gradient grayscale based on the mask sampling results using a preset smoothed step function to obtain the gradient grayscale result. In this embodiment, the gradient grayscale result can be obtained by performing attenuation calculation on the mask sampling results using a preset smoothed step function. Figure 9 The image shown is a gradient grayscale result; no specific limitation is made here.

[0062] The beam animation generation method provided by the above embodiments uses a patch model as the carrier and rendering object of the beam animation, which can avoid the waste of rendering resources caused by rendering beam animation based on the camera in the scene. By performing polar coordinate transformation on the initial texture coordinate data of the patch model and then performing frame-by-frame superposition sampling of the time offset variable, dynamic sampling results can be generated. Then, by masking the sampling results with a mask map, dynamic target planar beam animation within the mask range can be obtained, thereby quickly obtaining planar beam animation without rotating the viewpoint and reducing the waste of rendering resources.

[0063] For the corresponding method embodiments described above, see [link to relevant documentation]. Figure 10The diagram shows a device for generating beam animation. The device includes: a construction module 1000, used to create a patch model and perform polar coordinate transformation on the initial texture coordinate data of the patch model to obtain target polar coordinate data; a sampling module 1020, used to perform frame-by-frame superposition of the target polar coordinate data with time offset variables to obtain sampling coordinate data corresponding to each frame, and to sample a preset base map frame-by-frame using the sampling coordinate data corresponding to each frame to obtain the target sampling result corresponding to each frame; and a masking module 1040, used to sample a preset mask map to obtain a masking sampling result, and to superimpose the masking sampling result with the target sampling result corresponding to each frame to obtain the target planar beam animation.

[0064] The aforementioned beam animation generation device uses a patch model as the carrier and rendering object for beam animation, which avoids the waste of rendering resources caused by rendering beam animation based on the camera in the scene. By performing polar coordinate transformation on the initial texture coordinate data of the patch model and then performing frame-by-frame superposition sampling of the time offset variable, dynamic sampling results can be generated. Then, by masking the sampling results with a mask map, dynamic target planar beam animation within the mask range can be obtained, thereby quickly obtaining planar beam animation without rotating the viewpoint and reducing the waste of rendering resources.
