Description
Technical Field
The invention relates to the field of computer graphic rendering, in particular to a method and a device for hybrid processing of texture maps, electronic equipment and a storage medium.
Background
In computer graphics, it is generally required to render a virtual model, for example, in the field of games, it is required to render a virtual character, a virtual terrain, and the like in a game, wherein Texture Blend (Texture Blend) is a common rendering technique. In the construction process of some complex scenes, the texture mixing processing is carried out on the images, so that the four-side continuous textures made of various different materials can obtain soft and natural transition effects at the boundary.
In the process of constructing some large game scenes, if the UV maps of the ground surface in the game scene are all expanded and the texture map is given to each position of the map, great texture resources are consumed, and the pressure of texture reading on rendering power consumption is greatly increased. At present, four continuous maps are generally made for various earth surfaces, and the vertex color of the virtual model is used to record the texture map corresponding to the position in the map to be rendered. Because the to-be-rendered map is four-sided continuous, the to-be-rendered map does not generate a splicing seam, but texture mixing needs to be performed on the shader algorithm level when the transition effect of the to-be-rendered map is processed at the junction of different textures.
In the prior art, texture blending of a to-be-rendered map is usually implemented based on a height texture, that is, a height map (or an Alpha color channel of an existing map) is used to record height information of all parts of the height texture, and then the height information is used to participate in blending calculation, so as to obtain a blending effect, for example, a blending effect that conforms to a common real surface. However, in the hybrid algorithm based on the height texture, an additional texture map needs to be made to record the height information of all parts of the texture, and the additional map needs to be loaded when the map to be rendered is rendered.
In addition, in the prior art, the above-mentioned height information may also be recorded by using a textured Alpha color channel, however, in a scheme of recording the height information by using an Alpha color channel, the color channel is required to be in an idle state and cannot be occupied by other information, the data amount of an image is increased, and some rendering engines or mobile phone operating systems cannot read the data recorded by the channel.
In view of the above problems, no effective solution has been proposed.

Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
In accordance with an embodiment of the present invention, there is provided a method embodiment for hybrid processing of texture maps, it being noted that the steps illustrated in the flowchart of the figure may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that presented herein.
In addition, it should be further noted that a rendering terminal that renders an image may be an execution subject of the present embodiment. The rendering terminal may have a display device to display the image before rendering and the image after rendering. The rendering terminal is also provided with a processor to perform hybrid rendering on the images by adopting the method provided by the embodiment.
Fig. 1 is a flowchart of a hybrid processing method of texture mapping according to an embodiment of the present invention, as shown in fig. 1, the method including the steps of:
step S102, color information corresponding to each pixel in the texture image to be processed is obtained.
In step S102, the texture image to be processed is composed of pixels, each pixel having corresponding color information, wherein the color information corresponding to each pixel can be determined by three color components of red, green and blue, which are stored in three color channels.
Optionally, when the user needs to perform hybrid texture rendering on the texture image to be processed, the user determines the texture image to be rendered from the plurality of images stored in the local memory through the rendering terminal. And the rendering terminal reads the texture image to be processed from the local memory according to the operation instruction of the user, and analyzes the texture image to be processed to obtain the color information corresponding to each pixel contained in the texture image to be processed.
And step S104, determining the height information corresponding to each pixel in the texture image to be processed according to the color information corresponding to each pixel.
It should be noted that, the texture brightness change in the texture image to be processed generally has a corresponding relationship with the height information of the texture, for example, the height corresponding to the darker area in the texture image to be processed is relatively low, so in practical application, the rendering terminal may calculate the luminance information corresponding to each pixel according to the color information corresponding to each pixel, and finally, map the luminance information to obtain the height information.
In addition, it should be noted that the height information is extracted approximately through the color information included in the texture image to be processed, and a height map does not need to be created, so that the volume of the map used in the process of map mixing is reduced, and the rendering efficiency of the texture image to be processed is improved.
And step S106, performing texture mixing processing on the texture image to be processed based on the height information corresponding to each pixel to obtain a target texture image.
Optionally, in step S106, after obtaining the height information corresponding to the texture image to be processed, the rendering terminal does not record the height information in the height map or in a preset channel (e.g., Alpha color channel), but directly uses the height information for texture mixing. When the rendering terminal performs texture mixing processing on the texture image to be processed, the existing texture mixing algorithm can be adopted for texture mixing.
Based on the solutions defined in steps S102 to S106, it can be known that, in the embodiment of the present invention, a texture mixing processing manner is adopted for the texture image by directly using the height information, after the color information corresponding to each pixel in the texture image to be processed is obtained, the height information corresponding to each pixel in the texture image to be processed is determined according to the color information corresponding to each pixel, and the texture mixing processing is performed on the texture image to be processed based on the height information corresponding to each pixel, so as to obtain the target texture image.
It is easy to note that, in the above process, in the process of performing texture mixing on the texture image to be processed, the original color information of the texture image to be processed is used to extract the height information, and the height information is not required to be recorded by using a height map, or an additional channel, and the height information can be directly used for performing texture mixing, so that the manufacturing process of the height map is reduced, the map capacity used in the process of mixing the maps is reduced, the resource consumption in the process of performing texture mixing processing on the texture image is reduced, and the rendering efficiency is improved.
Therefore, the scheme provided by the application achieves the purpose of performing mixed rendering on the texture image to be processed, the technical effect of improving the mixed rendering efficiency of the texture image to be processed is achieved, and the technical problem that the rendering efficiency is low when the texture is mixed on the image in the prior art is solved.
In an optional embodiment, after obtaining the color information corresponding to each pixel in the texture image to be processed, the rendering terminal may determine the color value of each color channel corresponding to each pixel in the texture image to be processed according to the color information corresponding to each pixel, calculate the luminance information corresponding to each pixel according to the color value of each color channel corresponding to each pixel in the texture image to be processed, and finally determine the height information corresponding to each pixel in the texture image to be processed according to the luminance information corresponding to each pixel.
Optionally, the color channels in the texture image to be processed may include three color channels of red, green, and blue, where the three color channels respectively store color values of corresponding colors.
It should be noted that the brightness information corresponding to each pixel in the texture image to be processed represents the brightness of each pixel in the texture image to be processed, the brightness of all pixels represents the brightness change of the texture in the texture image to be processed, and the brightness change of the texture in the texture image to be processed has a corresponding relationship with the height information included in the texture image to be processed.
Optionally, the rendering terminal may calculate the luminance information corresponding to the texture image to be processed by using any one of the following three manners.
The first method is as follows: and the rendering terminal determines the color value of each color channel corresponding to each pixel in the texture image to be processed according to the color information corresponding to each pixel, acquires the color coefficient of each color channel, and then performs weighted summation on the color value of each color channel and the color coefficient of each color channel to obtain the brightness information corresponding to each pixel in the texture image to be processed. Wherein the color coefficient of each color channel is different.
Optionally, the color values corresponding to the three color channels of red, green, and blue are color.r, color.g, and color.b, respectively, and the luminance information corresponding to each pixel in the texture image to be processed may satisfy the following formula:
Brightness＝Color.r*0.2125+Color.g*0.7154+Color.b*0.0721
in the above equation, Brightness is luminance information corresponding to each pixel, and 0.2125, 0.7154, and 0.0721 correspond to color coefficients of three color channels of red, green, and blue, respectively. The color depth coefficients of the three color channels are empirical values and can be adjusted according to actual application requirements.
The second method comprises the following steps: and the rendering terminal determines the color value of each color channel corresponding to each pixel in the texture image to be processed according to the color information corresponding to each pixel, and calculates the average value of the color values of each color channel to obtain the brightness information corresponding to each pixel in the texture image to be processed. Optionally, the luminance information corresponding to each pixel may satisfy the following formula:
Brightness＝(Color.r+Color.g+Color.b)/3，
in the above equation, Brightness is luminance information corresponding to each pixel.
The third method comprises the following steps: and the rendering terminal determines a target color value of a target color channel corresponding to each pixel in the texture image to be processed according to the color information corresponding to each pixel, and determines the target color value corresponding to each pixel as the brightness information corresponding to each pixel in the texture image to be processed. The target color channel is any one of a plurality of color channels corresponding to the texture image to be processed. That is, in this manner, the color value corresponding to each color channel can be used as the luminance information, that is, the luminance information can satisfy the following formula:
bright ness color r or
Bright ness ═ color. g or
Brightness＝Color.b；
It should be noted that the three calculation methods can be used as static branches in a shader, a macro switch is arranged in a rendering program on a rendering terminal, and a user can adjust the macro switch according to actual needs to select different calculation methods to calculate brightness information. For example, in actual rendering, when the rendering terminal has a high requirement for rendering power consumption (i.e., the rendering terminal cannot execute a rendering program with high power consumption), the user may select the mode with a smaller calculation amount to calculate the brightness information.
In addition, it should be further noted that, in this embodiment, hybrid texture rendering of the texture image to be processed is implemented by using the height information, and the height information is obtained by approximating the brightness information, so that the accuracy requirement on the calculation result of the brightness information is not high in this application.
In addition, since there may be too large or too small request for the light and shade variation interval of the texture of different materials, it is not enough to obtain the brightness information corresponding to each pixel by any one of the above-mentioned one-way to three-way methods as the height information, for example, fig. 2 shows a texture map and a height map, where the height map corresponding to the texture 01 is a texture 01 height map, the height map corresponding to the texture 02 is a texture 02 height map, and fig. 3 shows a brightness map corresponding to the texture 02, where the brightness map corresponding to the texture 01 is a texture 01 brightness, and the brightness map corresponding to the texture 02 is a texture 02 brightness, and as can be seen from fig. 2 and 3, if the brightness of the texture 01 and the brightness of the texture 02 are directly taken as the height of the texture image, the difference between the texture 01 brightness and the texture 01 height map is large, and similarly, the difference between the texture 02 brightness and the texture 02 height map is also large, therefore, rendering results obtained by rendering the rendering image to be processed are greatly different. Therefore, in order to avoid the above problem, the present embodiment further maps the luminance information to obtain the height information of the rendered image to be processed.
Specifically, the rendering terminal determines height information corresponding to each pixel in the texture image to be processed according to the brightness information corresponding to each pixel. Specifically, the rendering terminal maps a first numerical range corresponding to the brightness information corresponding to each pixel into a second numerical range, and adjusts the brightness information corresponding to each pixel based on a first numerical value and a second numerical value corresponding to the second numerical range to obtain height information corresponding to each pixel in the texture image to be processed, where the first numerical value is an upper limit value of the second numerical range, and the second numerical value is a lower limit value of the second numerical range.
Optionally, in the process of adjusting the brightness information corresponding to each pixel based on the first numerical value and the second numerical value corresponding to the second numerical value range to obtain the height information corresponding to each pixel in the texture image to be processed, the rendering terminal calculates a difference between the first numerical value and the second numerical value to obtain a first result, calculates a product of the first result and the brightness information corresponding to each pixel to obtain a second result, and then calculates a sum of the second result and the second numerical value to obtain the height information corresponding to each pixel. That is, the height information can be represented by the following equation:
Height0＝Brightness*(B–A)+A
in the above formula, Height0 is Height information, B is a first value, and A is a second value.
From the above formula, when Brightness is 0, Height0 is a; when Brightness is 1, Height0 is B. Therefore, the change range of the brightness information can be changed from 0-1 (namely, the first numerical value range) to A-B (namely, the second numerical value range) by the above formula.
It should be noted that the first numerical value and the second numerical value in the rendering program running in the rendering terminal may be opened to the user, that is, the user may adjust the first numerical value and the second numerical value through the rendering terminal to obtain a numerical range of the required height information, so as to obtain an ideal mixed rendering result. For example, the sand texture is relatively gentle (i.e., the height difference is small), and therefore, the user may adjust the first value and the second value corresponding to the sand texture to two relatively close values, for example, adjust the first value and the second value to two values whose difference is smaller than a first preset difference; for another example, the difference between the height and the height of the masonry texture is large, the user may adjust the first value and the second value corresponding to the masonry texture by two values that are different from each other, and the height of the sand texture may form a better interpenetration, for example, the first value and the second value are adjusted by two values that are different from each other by a second preset difference, optionally, the a brick is < a sand, the B brick is > B sand, for example, the a sand is 0.3, the B sand is 0.7, the a brick is-0.4, and the B brick is 1.5. The sand A and the sand B respectively represent a first numerical value and a second numerical value corresponding to sand textures, and the brick A and the brick B respectively represent a first numerical value and a second numerical value corresponding to masonry textures.
In an optional embodiment, after the brightness information corresponding to each pixel is adjusted based on the first numerical value and the second numerical value corresponding to the second numerical value range to obtain the height information corresponding to each pixel in the texture image to be processed, the rendering terminal further performs mapping processing on the height information corresponding to each pixel to obtain target height information, and the target height information is within the first numerical value range.
It should be noted that, in the process of mapping the luminance information to the height information, a condition of a <0 > or B >1 may occur, so that the numerical range of the height information exceeds the interval of 0-1, and in order to ensure the correct row of the subsequent height texture mixing calculation result, the numerical range of the height information needs to be ensured to be between 0 and 1. Therefore, the height information can be subjected to the mapping process by the following equation:
Height＝saturate(Height0)
in the above equation, Height is the target Height information, and the saturrate (x) function can force the value of x to be in the range of 0 to 1, i.e., if x <0, saturrate (x) returns a value of 0; if x >1, saturrate (x) returns a value of 1; if 0 ≦ x ≦ 1, then saturate (x) returns a value of x.
It should be noted that, a user may obtain approximately correct height fitting data by adjusting the first numerical value and the second numerical value of the above formula, for example, in the height fitting result diagram shown in fig. 4, the height fitting result of the texture 01 and the height fitting result of the texture 02 are height maps obtained by using the method provided in this embodiment, and are not different from the height maps of the texture 01 and the height maps of the texture 02.
According to the method, the height information is approximately extracted by utilizing the original color information of the texture, the manufacturing process of the height map is reduced, the volume of the map used when the map is mixed is reduced, the final mixing effect can be flexibly controlled, on one hand, the correct result close to the mixing effect of the height information can be achieved, on the other hand, the final effect can be more flexibly controlled by art manufacturing personnel, and the mixing result can better meet the art requirements.
In addition, under the condition that the height mapping is omitted, the height information of each position of the texture is approximately obtained through a simple algorithm and acts on a height-based texture mixing algorithm, so that the manufacturing cost of the height mapping is saved, the use and the loading of the mapping in the rendering process are reduced, and the rendering efficiency of texture mixing is improved.
According to an embodiment of the present invention, there is also provided an embodiment of a hybrid processing apparatus for texture mapping, where fig. 5 is a schematic diagram of the hybrid processing apparatus for texture mapping according to the embodiment of the present invention, as shown in fig. 5, the apparatus includes: an acquisition module 501, a determination module 503, and a processing module 505.
