In the related art, the interactive effect is usually simulated by a simple special effect, which has a relatively simple implementation process but poor visual performance. Alternatively, a complex physical or fluid algorithm is used, which has a realistic visual performance but a large amount of calculation and high performance consumption, and is difficult to run smoothly on a mobile device and has poor compatibility.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0014] Currently, rendering interactive effects between characters and water is a common requirement in game development. For example, when a character or object falls into water, corresponding interactive effects need to be generated on the water surface. Traditional games typically achieve this effect in two ways: one is through simple water splash effects, which is simple to implement but visually poor; the other is by using complex physics or fluid algorithms, which, while producing realistic effects, involves high computational demands, high performance consumption, and is difficult to run smoothly on mobile devices, also exhibiting poor compatibility. Based on this, the embodiments of this disclosure provide a rendering method, apparatus, and electronic device for visual interactive effects, which can be applied to games with rendered effects.

[0015] To facilitate understanding of this embodiment, a method for rendering visual interactive effects disclosed in this disclosure will first be described in detail. A graphical user interface (GUI) is provided through a terminal device. The GUI includes at least a portion of a virtual scene, such as... Figure 1 As shown, the method includes the following steps: Step S102: In response to the interaction between the interactive model and the target model in the virtual scene, control the particle emitter mounted on the interactive model to emit a pre-set normal map; wherein, the normal map includes normal information representing the interaction effect; The aforementioned interactive models typically refer to models capable of moving and interacting according to physical laws, such as virtual character models, virtual stone models, and virtual baseball models. Similarly, the aforementioned target models also typically refer to models capable of moving and interacting according to physical laws; these could be water models, such as static or flowing water models, or sand models, plastic models, etc. The aforementioned interactive behaviors typically refer to contact between the interactive model and the target model, such as the interactive model falling onto the surface of the target model, or the interactive model colliding with the target model. The aforementioned particle emitters can be mounted at designated locations on the interactive models, such as below or in front of them.

[0016] The aforementioned particle emitters typically have multiple pre-configured normal maps. Each normal map includes a target area representing an interactive effect, such as a water ripple effect or an oscillation effect. Therefore, these normal maps usually include a water ripple area, which is typically a circular area. The radius of the water ripples varies between different normal maps. The normal information in these normal maps represents the interactive effect on the target model's surface.

[0017] Optionally, determine the interaction position between the interactive model and the target model; control the particle emitter mounted on the interactive model to emit a pre-set normal map to the interaction position.

[0018] Optionally, taking a water ripple effect as an example, the explanation involves controlling the particle emitter mounted on the interactive model to emit multiple normal maps in succession. For example, a normal map is emitted every 0.1 seconds. Typically, the radius of the water ripple in the first emitted normal map is the first radius value, and the radius of the subsequent emitted normal maps is the second radius value, where the first radius value is smaller than the second radius value.

[0019] The aforementioned normal information typically refers to three-dimensional vector information, including the X-axis vector, Y-axis vector, and Z-axis vector.

[0020] Step S104: Render the normal map onto a preset texture to obtain the target texture, and blend the normals of the target texture with the vertex normals of the target model to obtain the target vertex normals of the target model. Optionally, the normal map is rendered to a preset texture to obtain the target texture, the target texture is sampled, and the sampling result is blended with the vertex normals of the target model to obtain the target vertex normals of the target model. The aforementioned preset texture typically refers to a RenderTexture (RT), generally understood as a special "canvas" or "camera + display". Rendering the normal map to a preset texture specifically means that the result of the rendering operation is stored in a texture image in memory, rather than being directly drawn to the screen. Normal rendering usually involves rendering the normal map directly to the screen, while the aforementioned rendering of the normal map involves rendering it to a preset texture. When it needs to be displayed on the screen, this preset texture needs to be sampled and rendered again.

[0021] To improve rendering performance, the resolution of the aforementioned preset textures is typically 512 or 256, or lower. For example, such as... Figure 2 A schematic diagram of the target texture is shown.

[0022] The above sampling results usually refer to normal information. The sampled normal information is mixed with the vertex normals of the volume model. For example, the sampled normal information is directly added to the vertex normals of the target model, or the average value is calculated.

[0023] Optionally, sampling is performed on the first position of the target texture to obtain the sampling result of the first position. The model vertex corresponding to the first position is determined from the target model. The sampling result of the first position is mixed with the vertex normal of the model vertex to obtain the target vertex normal of the model vertex corresponding to the first position in the target model.

[0024] Step S106: Render an image representing the interactive effect on the surface of the target model based on the target vertex normal.

[0025] Taking the water ripple effect as an example, water ripples are rendered on the surface of the target model based on the target vertex normal, and the movement of the water ripples is controlled according to the preset particle parameters to obtain the water ripple effect corresponding to the interactive behavior.

[0026] Specifically, the target model is rendered based on the target vertex normals to make the surface of the target model display a water ripple effect.

[0027] The preset particle parameters mentioned above refer to the particle parameters of the normal map, as the particle emitter pre-sets the particle parameters for each normal map. These preset particle parameters typically include lifecycle parameters and variation parameters. If the interactive effect is a water ripple effect, the variation parameters include: water ripple color parameters, transparency parameters, and intensity parameters. The intensity refers to the bump intensity of the water ripple.

[0028] In actual implementation, the water ripples are controlled to gradually increase in size according to preset particle parameters, the vertex colors of the water ripples gradually become more transparent according to preset particle parameters, and the intensity of the water ripples gradually decreases according to preset particle parameters, in order to achieve a dynamic effect of water ripples. That is, after the interactive model comes into contact with the target model, concentric circles of water ripples appear on the water surface until each ripple gradually disappears. For example, Figure 3 The diagram shows a water ripple effect.

[0029] This disclosure provides a method for rendering visual interactive effects. In response to an interaction between an interactive model and a target model in a virtual scene, a particle emitter mounted on the interactive model emits a pre-set normal map. The normal map includes normal information representing the interactive effect. The normal map is rendered onto a preset texture to obtain a target texture. The normals of the target texture are then blended with the vertex normals of the target model to obtain the target vertex normals of the target model. An image representing the interactive effect is generated by rendering on the surface of the target model based on the target vertex normals. In this method, by emitting a normal map using a particle emitter, rendering the normal map onto a preset texture, and sampling and blending the preset texture with the vertex normals of the target model, a water ripple effect can be rendered based on the blended vertex normals. This method is not only simple to implement and has low performance consumption, but also achieves realistic visual effects, thereby improving compatibility. One possible implementation of the above steps for rendering the normal map onto a preset texture to obtain the target texture is as follows: create a first virtual camera and control the first virtual camera to capture the normal map; render the captured image from the first virtual camera onto a preset texture to obtain the target texture; wherein the texture coordinates of the target texture correspond to the screen coordinates of the terminal device.

[0030] The first virtual camera mentioned above is different from other virtual cameras in the game. It is a separate camera that takes pictures and renders normal maps, and renders them onto a preset texture (a screen space).

[0031] One possible implementation of the above-described step of blending the normals of the target texture with the vertex normals of the target model to obtain the target vertex normals of the target model is as follows: The target texture is sent to the shader corresponding to the target model. The shader samples the target texture for each screen coordinate of the terminal device based on the current screen coordinate, and obtains the sampling result. The sampling result is the normal information of the target texture corresponding to the current screen coordinate. The numerical range of the normal information is mapped to a preset range to obtain the target sampling result. The target sampling result is mixed with the vertex normal of the model vertex corresponding to the current screen coordinate in the target model to obtain the target vertex normal of the target model.

[0032] The range of normal information corresponding to the current screen coordinates in the target texture is usually [0,1]. Since the range of vertex normals in the target model is [-1,1], it is necessary to map the normal information corresponding to the current screen coordinates in the target texture to the range [-1,1] to obtain the target sampling result. Specifically, the mapping process can be performed as follows: (normal*2-1) where normal is the normal information corresponding to the current screen coordinates in the target texture.

[0033] Specifically, the target sampling result and the vertex normals of the model vertex corresponding to the current screen coordinates can be mixed using the method normalize(N1 + N2). Here, N1 is the target sampling result, and N2 is the vertex normal of the model vertex corresponding to the current screen coordinates. Normalize refers to standardizing the value obtained by adding N1 and N2, which means keeping the direction unchanged while scaling the length to a specified length (e.g., "1").

[0034] In another possible approach, the sampling results only include a first vector in the first direction and a second vector in the second direction. For example, a first vector in the X-axis direction and a second vector in the Y-axis direction. After obtaining the sampling results, the numerical range of the sampling results is first mapped to a preset range, and then a third vector in the third direction, such as the third vector in the Z-axis direction, is calculated using the sqrt(1 - x^2 - y^2) method.

[0035] The above technique can be implemented using the following code: float4 ringColor = tex2D( RingTex, screenPos); / / RingTex is the target texture mentioned above, screenPos is the screen coordinates mentioned above, and ringColor is the initial sampling result, which includes the ringColor of the color and alpha channels.

[0036] float3 ringNormal = UnpackNormal(ringColor).rgb; / / ringNormal refers to unpacking the normal information from ringColor, i.e., the sampling result mentioned above.

[0037] ringNormal = mul(float3x3(i.TtoW0.xyz,i.TtoW1.xyz,i.TtoW2.xyz),ringNormal); / / Transforms ringNormal from tangent space to world space through matrix multiplication, specifically using the transformation matrix from tangent space to world space (composed of variables such as i.TtoW0).

[0038] ringNormal = normalize(ringNormal)*ringColor.a*_RingPower; / / Normalize ringNormal, then multiply by the Alpha channel of ringColor (to control intensity) and the external parameter _RingPower (to adjust the overall intensity of the ring effect), corresponding to the range mapping mentioned above.

[0039] / / float3 normal = BlendNormals(ringNormal,waterNormal); float3 normal =normalize(waterNormal+ringNormal); This can be achieved through BlendNormals, which mixes ringNormal (the target sampling result mentioned above) and waterNormal (the vertex normal of the model vertex corresponding to the current screen coordinates), or through normalization.

[0040] The aforementioned normal map includes a target region representing the interactive effect, which stores normal information representing the interactive effect; one possible implementation of the step of rendering an image representing the interactive effect based on the target vertex normals on the surface of the target model is as follows: An initial interaction effect image is generated on the surface of the target model based on the target vertex normal. The movement of this initial interaction effect image is controlled according to preset particle parameters, and an image representing the interaction effect corresponding to the interaction behavior is generated on the surface of the target model. The preset particle parameters are determined based on the attributes of the interaction model and the target model, and / or the interaction method between them. Specifically, different effects of different object interactions or different interaction methods are adjusted through parameter control. The initial interactive effect image described above can be water ripples, vibration patterns, etc. Optionally, the water ripple movement can be controlled according to preset particle parameters to generate water ripple effects corresponding to the interactive behavior on the surface of the target model.

[0041] The aforementioned preset particle parameters include at least life cycle parameters and variation parameters. The life cycle parameter is used to control the display time of the initial interactive effect image, while the variation parameter is used to control the dynamic variation effect of the initial interactive effect, such as the interaction range (e.g., the radius of water ripples or oscillations), the transparency of the image representing the interactive effect, and the intensity of the bumps.

[0042] One possible implementation of the above steps for controlling the movement of the initial interactive effect image according to preset particle parameters is as follows: controlling the initial interactive effect image to gradually disappear as the life cycle parameter is defined; controlling the dynamic change effect of the initial interactive effect image to gradually change according to the change parameter.

[0043] The changing parameters include: a first changing parameter; the step of controlling the dynamic changing effect of the initial interactive effect image to gradually change according to the changing parameter includes: controlling the range of the interactive effect of the initial interactive effect image to gradually increase according to the first changing parameter.

[0044] The changing parameters include: a second changing parameter; the step of controlling the dynamic changing effect of the initial interactive effect image to gradually change according to the changing parameters includes: controlling the transparency of the initial interactive effect image to gradually increase according to the second changing parameter.

[0045] The changing parameters include: a third changing parameter; the step of controlling the dynamic changing effect of the initial interactive effect image to gradually change according to the changing parameters includes: controlling the bump intensity of the initial interactive effect image to gradually decrease according to the third changing parameter. If the initial interactive effect image is a wave effect image; the dynamic changing effect includes one or more of the following: change range, transparency, and bump intensity; Optionally, the aforementioned changing parameters include: a first changing parameter, a second changing parameter, and a third changing parameter; One possible implementation of the above steps for controlling the dynamic changes of the initial interactive effect diagram according to the gradually changing parameters is as follows: The range of change of the fluctuation effect diagram is controlled to gradually increase according to the first change parameter; The transparency of the fluctuation effect diagram is controlled to gradually increase according to the second change parameter; The intensity of the undulation in the wave effect diagram is controlled to gradually decrease according to the third variation parameter.

[0046] Specifically, taking the water ripple effect as an example, the preset particle parameters include at least: a lifecycle parameter, a first change parameter, a second change parameter, and a third change parameter. The first change parameter controls the radius of the water ripple, the second change parameter controls the transparency of the water ripple, and the third change parameter controls the degree of unevenness or convexity of the water ripple. Higher transparency results in a lighter color or more transparent water ripple, and lower unevenness or convexity.

[0047] One possible implementation of the above steps for controlling the movement of water ripples according to preset particle parameters is as follows: controlling the water ripples to simultaneously perform at least one or more of the following steps: controlling the water ripples to gradually disappear with the life cycle parameter; controlling the radius of the water ripples to gradually increase according to a first variation parameter; controlling the transparency of the water ripples to gradually increase according to a second variation parameter; and controlling the unevenness intensity of the water ripples to gradually decrease according to a third variation parameter.

[0048] For example, with a lifecycle parameter of 5 seconds, the water ripples gradually disappear as the countdown reaches 5 seconds. The first variable parameter is 8, which controls the radius of the water ripples to gradually increase to 8 as the countdown reaches 5 seconds. The second variable parameter is 90%, which controls the transparency of the water ripples to gradually increase to 90% as the countdown reaches 5 seconds. The third variable parameter is 10%, which controls the intensity of the ripples to gradually decrease to 10% as the countdown reaches 5 seconds.

[0049] One possible implementation of the above-described step of controlling the particle emitter mounted on the interactive model to emit a pre-set normal map is as follows: determine the interaction position between the interactive model and the target model; control the particle emitter mounted on the interactive model to emit the pre-set normal map to the interaction position.

[0050] The aforementioned particle emitter is pre-configured with multiple normal maps, and these normal maps correspond to a specified emission order. Another possible implementation of the step of controlling the particle emitter mounted on the interactive model to emit the pre-set normal maps is as follows: according to the specified emission order, control the particle emitter mounted on the interactive model to emit the corresponding normal maps.

[0051] The interactive effect ranges corresponding to the above multiple normal maps are different, and the interactive effect range corresponding to the normal map is proportional to the order value corresponding to the emission order of the normal map.

[0052] Optionally, the particle emitters mounted on the interactive model can be controlled to emit corresponding normal maps at preset intervals according to a specified firing order. The preset intervals can be 1 second, 0.5 seconds, etc., and can be pre-configured according to the game's needs.

[0053] Taking a water ripple effect as an example, the particle emitter is pre-configured with five normal maps: the first normal map, the second normal map, the third normal map, the fourth normal map, and the fifth normal map. The emission order of the first normal map is "1", with a corresponding numerical value of "1". The emission order of the second normal map is "2", with a corresponding numerical value of "2". The emission order of the third normal map is "3", with a corresponding numerical value of "3". The emission order of the fourth normal map is "4", with a corresponding numerical value of "4". The emission order of the fifth normal map is "5", with a corresponding numerical value of "5". The particle emitter is controlled to first emit the first normal map, then the second normal map after 1 second, the third normal map after 2 seconds, the fourth normal map after 3 seconds, and the fifth normal map after 4 seconds. Among them, the radius of the water ripples of the first normal map (i.e. the corresponding interactive effect range) is smaller than the radius of the water ripples of the second normal map, the radius of the water ripples of the second normal map is smaller than the radius of the water ripples of the third normal map, the radius of the water ripples of the third normal map is smaller than the radius of the water ripples of the fourth normal map, and the radius of the water ripples of the fourth normal map is smaller than the radius of the water ripples of the fifth normal map.

[0054] The above methods also include: (1) Generate the first texture; The first texture usually refers to a grayscale image, which can be a circle, a rectangle, etc.

[0055] (2) For each pixel in the first texture, determine the color value of the pixel based on the preset control parameters; In one possible approach, for each pixel in the first texture, it is determined whether the pixel is located within the water ripple area according to pre-configured control parameters. If not, the color value of the pixel is determined to be a first color value; if so, the color value of the pixel is determined to be a second color value.

[0056] In another possible approach, a target region in the first texture is determined according to pre-set control parameters; wherein the target region includes edge regions and non-edge regions; if a pixel is not located in the target region, the color value of the pixel is determined to be a first color value; if the pixel is located in a non-edge region, the color value of the pixel is determined to be a second color value; if the pixel is located in an edge region, the color value of the pixel is determined to be a third color value; wherein the third color value is less than the second color value and greater than the first color value. The first color value is 0, the second color value is 1 (0 represents black, 1 represents white), and the third color value is less than 1 and greater than 0. Taking the water ripple effect as an example, the pre-set control parameters mentioned above include at least: the width of the water ripple, the range of the water ripple (such as the maximum diffusion distance of the water ripple), and the edge transition value of the water ripple. It usually also includes: Render Queue (controls the rendering queue and determines the order in which objects are drawn, affecting effects such as transparency and occlusion), Enable GPU Instancing (enables GPU instantiation, batch rendering of identical objects to optimize performance), and Double Sided Global Illumination (enables double-sided global illumination, allowing both the front and back sides of the object to participate in global illumination calculations, affecting lighting and shadow effects).

[0057] Optionally, firstly, based on the effective range and width of the ripple effect in the control parameters, determine the first edge value and the second edge value of the ripple. Then, based on the edge transition value and the first edge value in the control parameters, determine the first transition value of the first edge value. Next, based on the edge transition value and the second edge value in the control parameters, determine the second transition value of the second edge value. Determine the distance between the pixel and the center point of the first texture. Use the first edge value, the first transition value, and this distance value as the first input value of the objective function, and determine the first output value of the pixel based on the objective function. Use the second edge value, the second transition value, and this distance value as the second input value of the objective function, and determine the second output value of the pixel based on the objective function. The difference between the first output value and the second output value is determined as the color value of the pixel.

[0058] Specifically, the difference between the effective range of the water ripple and the width of the water ripple is calculated to obtain the first edge value threshold1; the sum of the effective range of the water ripple and the width of the water ripple is calculated to obtain the second edge value threshold2; the sum of the first edge value and the edge transition value smoothness of the water ripple is calculated to determine the first transition value of the first edge value; the sum of the second edge value and the edge transition value smoothness of the water ripple is calculated to determine the second transition value of the second edge value; and the distance value dis between the pixel and the center point of the first texture is determined.

[0059] The first edge value, the first transition value, and the distance value are used as the first input values ​​of the objective function `smoothstep`. Based on the objective function, the first output value of the pixel is determined. That is, `value = smoothstep(threshold1, threshold1 + smoothness, dis)`. If `dis` is less than or equal to `threshold1`, the first output value is 0; if `dis` is greater than or equal to `threshold1 + smoothness`, the first output value is 1; if `dis` is less than `threshold1 + smoothness` but greater than `threshold1`, the first output value is `t = clamp((dis - threshold1) / (smoothness), 0.0, 1.0)`.

[0060] The second edge value, second transition value, and distance value are used as the second input value of the objective function. Based on the objective function, the second output value of the pixel is determined, and the difference between the first output value and the second output value is determined as the color value of the pixel. That is, value2 = smoothstep(threshold2, threshold2 + smoothness, dis). If dis is less than or equal to threshold2, the second output value is 0; if dis is greater than or equal to threshold2 + smoothness, the second output value is 1; if dis is less than threshold2 + smoothness but greater than threshold2, the second output value is t = clamp((dis – threshold2) / (smoothness), 0.0, 1.0).

[0061] For example, such as Figure 4 The diagram shown illustrates the normal map, where the white pixels represent the water ripple area.

[0062] (3) Based on the color value of the pixel, determine the normal information of the pixel and obtain the normal map.

[0063] Optionally, color values ​​are sampled in a specified direction at the pixel to obtain multiple sampling results; based on the multiple sampling results, a first vector and a second vector are determined; and the three-dimensional vector composed of the first vector, the second vector, and the preset vector is determined as the normal information of the pixel.

[0064] The numerical range of the normal information of the above pixels is [-1,1], and it needs to be mapped to [0,1] through mapping.

[0065] The specified direction refers to the front, back, left, and right of the pixel. The first sampling result is obtained by sampling the color value at a specified distance in front of the pixel, the second sampling result is obtained by sampling the color value at a specified distance behind the pixel, the third sampling result is obtained by sampling the color value at a specified distance to the left of the pixel, and the fourth sampling result is obtained by sampling the color value at a specified distance to the right of the pixel.

[0066] The difference between the first and second sampling results is calculated to obtain a first vector. The difference between the third and fourth sampling results is calculated to obtain a second vector. The preset vector is a vector perpendicular to the first and second vectors, and its value is 1.
