TECHNICAL FIELD

[0001] The present application relates to the technical field of special effect rendering, in particular to a rendering method and device of light stream effect and electronic equipment. BACKGROUND

[0002] The light stream effect is a common special effect in game and video rendering. In related technologies, mask information and color information of the light stream effect are needed to be prepared in advance. The mask information is used to control the shape and intensity of the light stream effect appearing area, and the color information is used to control the color and brightness of the light stream effect. The mask information and the color information are combined, and the combination result is superimposed on the basic color information of the model, so that the model with the light stream effect is rendered. In this way, the mask information needs to be prepared in advance. If the material of the model is complex, the mask information will also be complex, and the production cost will be high. In the process of rendering the light stream effect, a large storage space needs to be reserved to store the mask information, and a large power consumption is needed to load and read the mask information, which leads to low rendering efficiency of the light stream effect.

[0010] The steps for determining the final stream light intensity information based on the first stream light intensity information and the second stream light intensity information include: obtaining a first information adjustment parameter corresponding to the first stream light intensity information and a second information adjustment parameter corresponding to the second stream light intensity information; adjusting the first stream light intensity information based on the first information adjustment parameter to obtain a first intermediate result; adjusting the second stream light intensity information based on the second information adjustment parameter to obtain a second intermediate result; and determining the final stream light intensity information based on the first intermediate result and the second intermediate result.

[0011] The steps described above for rendering the flowing light effect of the pixels to be rendered on the target model based on the flowing light intensity information and the preset flowing light color information include: obtaining flowing light rendering information based on the flowing light intensity information and the preset flowing light color information; and superimposing the flowing light rendering information onto the basic rendering information of the pixels to be rendered on the target model to obtain a rendering result of the pixels to be rendered with a flowing light effect.

At the same time, during the rendering process, since the specified material texture map is also used for the regular rendering of the model, there is no need to reserve texture storage space for flowing light rendering, nor is there an additional power consumption to read texture information for the rendering of the flowing light effect, thus improving the rendering efficiency of the flowing light effect.

[0029] 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.

[0030] In related technologies, to control the area where the flowing light effect appears and the intensity of the flowing light effect in each area, a mask map needs to be created to store the masking information of the flowing light effect. During the rendering process, after sampling the masking information of this mask map, the flowing light intensity of different areas is multiplied by the previously calculated flowing light information to control the specific area where the flowing light appears and the intensity of the flowing light effect in each area.

[0031] The above method has the following drawbacks: An additional texture needs to be created to record the light intensity in different areas. When the model's material is complex, the mask texture will also be very complex, increasing the cost of art production and making it labor-intensive and time-consuming. During rendering, in order to obtain the light intensity information recorded in the mask texture, an additional loading and reading process is required, increasing rendering power consumption. For game development, the game project needs to store this mask texture, increasing the project's capacity. Moreover, the more complex the shape of the mask texture, the higher the required data precision, which necessitates a higher texture resolution and a larger data footprint.

[0032] Based on the above, the embodiments of the present invention provide a rendering method, apparatus and electronic device for a flowing light effect, which can be applied to rendering scenes of flowing light effects in games, animation and film.

[0033] To facilitate understanding of this embodiment, a method for rendering a flowing light effect disclosed in this invention will first be described in detail, such as... Figure 1 As shown, the method includes the following steps:

[0034] Step S102: Obtain the specified material texture of the target model; wherein, the specified material texture includes a metallic texture and / or a roughness texture.

[0035] In PBR (Physically-Based Rendering), when rendering the material of the target model's surface, it is necessary to read the metallic map and roughness map of the target model. For each pixel on the model's surface, metallic information is read from the metallic map and roughness information is read from the roughness map, and then the material is rendered for that pixel.

[0036] In this embodiment, the aforementioned mask texture is no longer set for rendering the flowing light effect. During the research process, the inventors discovered that the appearance area and intensity of the flowing light effect on the target model are directly related to the metallicity and roughness information of the area. Therefore, in this embodiment, the flowing light intensity information of each pixel in the target model is determined by a specified material texture of the target model. Specifically, depending on the specific requirements of the flowing light effect, the specified material texture may include only a metallicity texture, only a roughness texture, or both.

[0037] In PBR rendering, metallicity is a parameter used during the rendering process. Metallicity describes how many photons, upon reaching an object's surface, are almost directly reflected, while others enter the object and are reflected from other locations on its surface. A metallicity of 0 indicates only diffuse reflection, where all photons enter the object and are then reflected. A metallicity of 1 indicates only specular reflection, where all photons are directly reflected from the object's surface. The metallicity map stores the metallicity of each pixel in the target model.

[0038] Roughness is also a parameter in the PBR rendering process. Roughness describes the degree of roughness of the target model's surface. Generally, the smaller the roughness, the smoother the model surface; the larger the roughness, the rougher the model surface. The roughness map stores the roughness of each pixel position in the target model.

[0039] Step S104: Extract the texture information of the pixels to be rendered on the target model from the specified material texture map;

[0040] During the rendering process of a target model, it is usually necessary to render each pixel on the target model one by one. For example, when rendering pixel A, pixel A is the pixel to be rendered. Based on the position of the pixel to be rendered on the target model, the texture information of the pixel to be rendered is extracted from a specified material map. In actual implementation, this is usually done based on the UV coordinates of the pixel to obtain the texture information corresponding to the UV coordinates of the pixel in the specified material map. The process of extracting texture information can also be understood as the process of sampling the specified material map.

[0041] In the pixel shader of PBR rendering, the UV coordinates of the pixel to be rendered and the specified material map are obtained. The sampling function Sample is used to obtain the texture information corresponding to the UV coordinates in the specified material map. For example, sampling the metallic map will give the metallic information corresponding to the UV coordinates, and sampling the roughness map will give the roughness information corresponding to the UV coordinates.

[0042] It should be noted that metallicity maps and roughness maps are essential textures that must be read during the rendering process of the target model. That is, even when rendering a target model without a flowing light effect, metallicity maps and roughness maps must still be read. For a given pixel, after reading the metallicity from the metallicity map and the roughness from the roughness map, the metallicity and roughness are input into the relevant rendering algorithm to render the material and color of that pixel. In this embodiment, metallicity maps and roughness maps participate not only in the regular rendering of the target model but also in the rendering of the flowing light effect.

[0043] Step S106: Based on the above texture information and the preset texture information adjustment parameters, determine the light flow intensity information of the pixel to be rendered;

[0044] In this embodiment, the light flow intensity information of the pixel to be rendered needs to be determined based on the texture information extracted from the specified material texture. Texture information adjustment parameters can adjust the overall light flow effect. For example, increasing contrast can make the light flow intensity information of two pixels larger after adjusting the texture information parameters when the difference in texture information values ​​between the two pixels is small. Conversely, reversing contrast can make the light flow intensity information of a pixel larger after adjusting the texture information parameters when the texture information value of a pixel is small, and vice versa.

[0045] The texture information adjustment parameters mentioned above can be preset. For example, art staff can set these parameters to control the overall flow effect. The texture information adjustment parameters and texture information are used together in the calculation to obtain the flow intensity information. Specifically, a formula can be preset, with the texture information adjustment parameters as parameters in the formula. After inputting the texture information into the formula, the flow intensity information will be output.

[0046] Step S108: Based on the light intensity information and the preset light color information, render the light effect of the pixels to be rendered on the target model.

[0047] The light intensity information can control whether there is a light effect on the pixel to be rendered, as well as the intensity of the light effect. The light color information can control the color and brightness of the light of the pixel to be rendered. By combining the light intensity information and the light color information, the light effect of the pixel to be rendered can be obtained.

[0048] In one implementation, flowing light rendering information is obtained based on flowing light intensity information and preset flowing light color information. This flowing light rendering information is then superimposed on the base rendering information of the pixels to be rendered on the target model to obtain a rendering result with a flowing light effect for the pixels to be rendered. Specifically, the flowing light intensity information and the flowing light color information can be multiplied to obtain the flowing light rendering information. The base rendering information of the pixels to be rendered, i.e., the rendering information when the pixels do not have a flowing light effect, includes color information, material information, etc. The flowing light rendering information is superimposed on the base rendering information to obtain a rendering result with a flowing light effect for the pixels to be rendered.

[0049] For each pixel on the target model, the flowing light effect of that pixel can be obtained through the above method. After all pixels are rendered, the target model with the flowing light effect can be obtained.

[0050] The above-described method for rendering the flowing light effect involves obtaining a specified material texture map of the target model, where the specified material texture map includes a metallic texture map and / or a roughness texture map; extracting texture information of the pixels to be rendered on the target model from the specified material texture map; adjusting parameters based on the texture information and preset texture information to determine the flowing light intensity information of the pixels to be rendered; and rendering the flowing light effect of the pixels to be rendered on the target model based on the flowing light intensity information and preset flowing light color information. This method eliminates the need to create masking information for rendering the flowing light effect, as the flowing light intensity information can be obtained directly from the specified material texture map of the target model. This reduces the production cost of the flowing light effect. Furthermore, since the specified material texture map is also used for regular model rendering, there is no need to reserve texture storage space for flowing light rendering, nor is there an additional power consumption required to read texture information for the flowing light effect rendering, thus improving the rendering efficiency of the flowing light effect.

[0051] The following embodiments describe in detail the specific implementation method for determining the stream intensity information of the pixel to be rendered. Specifically, a transformation function is established by adjusting parameters based on texture information; the texture information is used as the input parameter of the transformation function for calculation to obtain the calculation result; and the stream intensity information of the pixel to be rendered is determined based on the calculation result.

[0052] The transformation function mentioned above can be a linear function, a quadratic function, etc., and the constant parameters in the transformation function are determined based on the texture information adjustment parameters. The higher the degree of the transformation function, the larger the number of texture information adjustment parameters required. This transformation function allows for linear adjustment of the texture information, ensuring a linear relationship between the texture information and the output stream intensity information.

[0053] In one specific implementation, the texture information adjustment parameters include a reference point parameter and a rate of change parameter. Based on the reference point parameter, the coordinate points along the function line corresponding to the transformation function to be established are determined. Based on the rate of change parameter, the slope of the transformation function to be established is determined. The transformation function is obtained through the coordinate points along the function line and the slope. In this method, the transformation function is a linear function, and the corresponding function line is a straight line. Determining a linear function requires only two constant parameters: one constant determines the position of the function line, and the other constant determines the slope of the function line. Therefore, the reference point parameter in the texture adjustment parameters is used to determine the coordinate points along the function line corresponding to the transformation function. Specifically, this reference point parameter can be the intersection of the function line with the X-axis or the intersection of the function line with the Y-axis in the coordinate system. The rate of change parameter is used to determine the slope of the transformation function. When the rate of change parameter is positive, the texture information is proportional to the output stream intensity information, and the larger the rate of change parameter, the greater the contrast of the stream intensity information. When the rate of change parameter is negative, the texture information is inversely proportional to the output light intensity information, and the larger the absolute value of the rate of change parameter, the greater the contrast of the light intensity information.

[0054] In the rendering scene, the transformation function can be implemented using the `lerp` function. The `lerp` function takes three input values: the reference point parameter, texture information, and the rate of change parameter. The function definition of `lerp` is: `lerp(reference point parameter, texture information, rate of change parameter) = reference point parameter + (texture information - reference point parameter) * rate of change parameter`. In the `lerp` function, the reference point parameter and the rate of change parameter are used to adjust the contrast of the stream light intensity information between different pixels. When the texture information and the reference point parameter are the same, the stream light intensity information output by the `lerp` function is the reference point information.

[0055] As an example, when the reference point parameter is 0 and the rate of change parameter is 1, the function line of the transformation function is as follows: Figure 2 As shown, Figure 3 yes Figure 2 The example shown is a transformation effect of the transformation function. Visually, the light intensity information does not change with the input texture information. It is more suitable for situations where the texture information and the light intensity required for the light effect are the same or similar.

[0056] As another example, when the baseline parameter is 0.4 and the rate of change parameter is 2, the function line of the transformation function is as follows: Figure 4 As shown, the transformation function amplifies the differences between the texture information of different pixels, increases the contrast of the light flow intensity, and the light flow intensity is greater where the texture information value is larger and less where the texture information value is smaller. Figure 5 yes Figure 4The example shown illustrates the transformation effect of the transformation function. Visually, brighter areas in the texture information become even brighter in the flowing light intensity information; darker areas in the texture information show little change in the flowing light intensity information. This can also be understood as the transformation function extracting the mask information for the flowing light effect from areas with larger texture values.

[0057] As a third example, when the baseline parameter is 0.4 and the rate of change parameter is -2, the function line of the transformation function is as follows: Figure 6 As shown, the contrast of the light flow intensity was reversed; where the texture information value was larger, the light flow intensity was smaller, and where the texture information value was smaller, the light flow intensity was larger. Figure 7 yes Figure 6 The example shown illustrates the transformation effect of the transformation function. Visually, darker areas in the texture information appear brighter in the flow light intensity information, while brighter areas in the texture information appear darker in the flow light intensity information. This can also be understood as the transformation function extracting the mask information for the flow light effect from areas with smaller texture values.

[0058] In addition, to avoid the output light flow intensity information being too large or too small, thus affecting the final rendered light flow effect, in this embodiment, if the calculation result is greater than a preset first threshold, the first specified value is set as the light flow intensity information of the pixel to be rendered; if the calculation result is less than a preset second threshold, the second specified value is set as the light flow intensity information of the pixel to be rendered; if the calculation result is between the first threshold and the second threshold, the calculation result is set as the light flow intensity information of the pixel to be rendered.

[0059] The first threshold, the first specified value, the second threshold, and the second specified value can all be set according to the requirements of the flowing light effect. As an example, if the first threshold is 1 and the first specified value is 1, then if the calculation result is greater than 1, the calculation result is set to 1; if the second threshold is 0 and the second specified value is 0, then if the calculation result is less than 0, the calculation result is set to 0.

[0060] In practical implementation, a saturation function can be set to limit the calculation results to the threshold range between the first and second thresholds, thereby limiting the final output stream intensity information to the threshold range.

[0061] When the specified material map only includes a metallic map, the texture information extracted from the metallic map is the metallic information. Based on the adjustment parameters corresponding to the metallic information, a transformation function is established, and then the metallic information is input into this transformation function to obtain the streamer intensity information. In this case, the streamer intensity information is determined only based on the metallic map, which is suitable when the metallic map closely matches the transformation requirements of streamer intensity, and there is no need to use a roughness map.

[0062] When the specified material map only includes a roughness map, the texture information extracted from the roughness map is the roughness information. Based on the adjustment parameters corresponding to the roughness information, a transformation function is established, and then the roughness information is input into this transformation function to obtain the streamer intensity information. In this case, the streamer intensity information is determined solely based on the roughness map, which is suitable when the roughness map closely matches the transformation requirements of the streamer intensity, and there is no need to use a metallic map.

[0063] However, when neither the metallicity map nor the roughness map can individually meet the requirements for streamer intensity transformation, it is necessary to refer to both the metallicity map and the roughness map simultaneously to obtain streamer intensity information. In this case, the metallicity map and the roughness map need to be processed separately using the methods described in the above embodiments to obtain the first streamer intensity information corresponding to the metallicity map and the second streamer intensity information corresponding to the roughness map. It should be noted that the adjustment parameters, transformation function, and the aforementioned first threshold, first specified value, second threshold, and second specified value for the texture information corresponding to the metallicity map can be the same as or different from the relevant values ​​corresponding to the roughness map. That is, the calculation process for the first streamer intensity information and the calculation process for the second streamer intensity information can be the same or different.

[0064] Based on the above, in one specific implementation, the specified material texture includes a metallic texture and a roughness texture; first flowing light intensity information corresponding to the metallic texture and second flowing light intensity information corresponding to the roughness texture are obtained; based on the first and second flowing light intensity information, the final flowing light intensity information is determined; based on the final flowing light intensity information and preset flowing light color information, the flowing light effect of the pixel to be rendered on the target model is rendered. In this method, the final flowing light intensity information is obtained by referring to the first flowing light intensity information corresponding to the metallic texture and the second flowing light intensity information corresponding to the roughness texture. The metallicity and roughness of the pixel simultaneously affect the flowing light intensity information of that pixel, making the adjustment of the flowing light intensity more flexible and versatile, and meeting diverse flowing light effect requirements.

[0065] Furthermore, the aforementioned first and second stream light intensity information can each be configured with information adjustment parameters. Specifically, the first information adjustment parameter corresponding to the first stream light intensity information and the second information adjustment parameter corresponding to the second stream light intensity information are obtained; the first stream light intensity information is adjusted based on the first information adjustment parameter to obtain a first intermediate result; the second stream light intensity information is adjusted based on the second information adjustment parameter to obtain a second intermediate result; and the final stream light intensity information is determined based on the first and second intermediate results. Here, the first information adjustment parameter can be understood as the weight of the first stream light intensity information, and the second information adjustment parameter can be understood as the weight of the second stream light intensity information. When the value of the first information adjustment parameter is large, the first stream light intensity information has a greater impact on the final stream light intensity information, that is, the pixel's metallicity information has a greater impact on the stream light intensity; when the value of the second information adjustment parameter is large, the second stream light intensity information has a greater impact on the final stream light intensity information, that is, the pixel's roughness information has a greater impact on the stream light intensity.

[0066] As an example, the final stream intensity information mentioned above can be calculated using the following formula:

[0067] LightflowMask = MaskRough * MaskRoughAmount + MaskMetal * MaskMetalAmount; where LightflowMask is the final stream intensity information, MaskRough is the second stream intensity information, MaskRoughAmount is the second information adjustment parameter; MaskMetal is the first stream intensity information, and MaskMetalAmount is the first information adjustment parameter.

[0068] The sum of the first information adjustment parameter and the second information adjustment parameter can be a fixed value, for example, the sum of the first information adjustment parameter and the second information adjustment parameter is equal to 1; the values ​​of the first information adjustment parameter and the second information adjustment parameter can also be independent of each other, and both parameters can be set to arbitrary values.

[0069] The above method utilizes metallicity and roughness information to approximate the region range information of the flowing light, which can reduce the mask texture creation process, lower the power consumption of flowing light rendering, and reduce unnecessary texture file size usage. Furthermore, artists can flexibly control the parameters adjusting the flowing light range, making the flowing light results more in line with artistic requirements.

[0070] For the corresponding method embodiments described above, see [link to relevant documentation]. Figure 8 The diagram shows a structural schematic of a rendering device for a flowing light effect, the device comprising:

[0071] The texture acquisition module 80 is used to acquire a specified material texture of the target model; wherein, the specified material texture includes a metallic texture and / or a roughness texture.

[0072] The information extraction module 82 is used to extract the texture information of the pixels to be rendered on the target model from the specified material texture map;

[0073] The information determination module 84 is used to determine the light intensity information of the pixel to be rendered based on the texture information and preset texture information adjustment parameters.

[0074] The rendering module 86 is used to render the flowing light effect of the pixels to be rendered on the target model based on the flowing light intensity information and the preset flowing light color information.

[0075] The aforementioned rendering apparatus for the flowing light effect acquires a specified material texture map of the target model; wherein the specified material texture map includes a metallic texture map and / or a roughness texture map; extracts texture information of the pixels to be rendered on the target model from the specified material texture map; determines the flowing light intensity information of the pixels to be rendered based on the texture information and preset texture information adjustment parameters; and renders the flowing light effect of the pixels to be rendered on the target model based on the flowing light intensity information and preset flowing light color information. In this method, there is no need to create masking information for the rendering of the flowing light effect. The flowing light intensity information can be obtained through the specified material texture map of the target model, and then the flowing light effect is rendered based on the flowing light intensity information, which reduces the production cost of the flowing light effect. At the same time, during the rendering process, since the specified material texture map is also used for the regular rendering of the model, there is no need to reserve texture storage space for the flowing light rendering, nor is there an additional power consumption to read texture information for the rendering of the flowing light effect, thus improving the rendering efficiency of the flowing light effect.

[0076] The aforementioned information determination module is also used for: adjusting parameters based on texture information to establish a transformation function; using texture information as input parameters of the transformation function to perform calculations and obtain calculation results; and determining the stream intensity information of the pixel to be rendered based on the calculation results.

[0077] The above-mentioned texture information adjustment parameters include reference point parameters and rate of change parameters; the above-mentioned information determination module is also used to: determine the coordinate points through which the function line corresponding to the transformation function to be established passes based on the reference point parameters; determine the slope of the transformation function to be established based on the rate of change parameters; and obtain the transformation function through the coordinate points through which the function line passes and the slope.

[0078] The aforementioned information determination module is further configured to: if the calculation result is greater than a preset first threshold, set the first specified value as the stream light intensity information of the pixel to be rendered; if the calculation result is less than a preset second threshold, set the second specified value as the stream light intensity information of the pixel to be rendered; if the calculation result is between the first threshold and the second threshold, set the calculation result as the stream light intensity information of the pixel to be rendered.

[0079] The specified material textures include metallic textures and roughness textures; the rendering module is further configured to: obtain first stream light intensity information corresponding to the metallic texture and second stream light intensity information corresponding to the roughness texture; determine the final stream light intensity information based on the first stream light intensity information and the second stream light intensity information; and render the stream light effect of the pixels to be rendered on the target model based on the final stream light intensity information and the preset stream light color information.

[0080] The rendering module described above is further configured to: obtain a first information adjustment parameter corresponding to the first stream light intensity information, and a second information adjustment parameter corresponding to the second stream light intensity information; adjust the first stream light intensity information based on the first information adjustment parameter to obtain a first intermediate result; adjust the second stream light intensity information based on the second information adjustment parameter to obtain a second intermediate result; and determine the final stream light intensity information based on the first intermediate result and the second intermediate result.

[0081] The above-mentioned rendering module is also used to: obtain flowing light rendering information based on flowing light intensity information and preset flowing light color information; and superimpose the flowing light rendering information onto the basic rendering information of the pixels to be rendered on the target model to obtain a rendering result of the pixels to be rendered with flowing light effect.

[0082] The rendering method and apparatus for the flowing light effect provided in this embodiment address the issue that, in a PBR rendering scene, material rendering inevitably requires the use of two texture information maps: roughness map and metallicity map. The area where the flowing light effect appears often has a direct correspondence with these two texture maps. Therefore, before the flowing light rendering calculation, these two texture maps can be directly subjected to linear transformations such as contrast adjustment. Then, these two texture maps can be superimposed with different weights as needed to obtain the flowing light range information that meets the artistic requirements. Finally, the above results can be substituted into the flowing light rendering calculation.

[0083] In the above method, for PBR rendering, the use of a streamer mask texture is eliminated. A simple algorithm is used to approximate the intensity information of the streamer at various locations, which is then applied to the streamer rendering algorithm. This eliminates the cost of creating a streamer mask texture and reduces the use and loading of textures during the rendering process, thereby improving the rendering efficiency of the streamer effect.
