Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the 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 the embodiment of the present invention, the offline rendering engine may decompose the rendering into different rendering elements, output the rendering elements to different element layers, and perform fine control on the final rendering effect (i.e., the effect map) by operating the element layers. In the embodiment of the present invention, two types of element layers are mainly used, where one type of element layer is an element layer that depends on illumination, and the method includes: the method comprises the steps of a global illumination layer (RAWGI), a reflection layer (REFLECT), a refraction layer (REFRACT), a highlight layer (SPECULAR), a scattering layer (SSS), a caustic layer (CAUSTICS), a fog layer (ATMOSPHERE), an exterior view layer (BACKGROUND), a self-luminous layer (SELFILUM) and the like, wherein the rendering of the element layers is long in time. Another type of element layers are element layers that are less dependent on illumination, including DIFFUSE reflection layers (DIFFUSE), which record colors and textures in the final effect map, and visually affect the definition of the colors and textures in the final effect map, and rendering of such element layers is very fast and time-consuming. And carrying out certain layer processing and layer merging and restoring to obtain a final effect graph.
Based on the above principle, as shown in fig. 1, an implementation flow diagram of the decoration effect graph generation method provided by the embodiment of the present invention is shown, and the method is applied to a processor, and specifically may include the following steps:
s101, obtaining a decoration scheme of a target scene, performing off-line rendering on the decoration scheme, and generating element layers depending on illumination and element layers not depending on illumination corresponding to the decoration scheme.
Currently, designers perform the design of finishing plans for target scenes (e.g., bedrooms) in 3D design software. After the designer finishes designing the decoration scheme of the target scene (such as a bedroom), the decoration scheme of the target scene is submitted and saved.
The embodiment of the invention can obtain the decoration scheme of the target scene, and call the offline rendering engine to perform offline rendering on the decoration scheme of the target scene to generate the illumination-dependent element layers and the illumination-independent element layers corresponding to the decoration scheme of the target scene.
It should be noted that, for each element layer depending on illumination, a global illumination layer (RAWGI), a reflection layer (REFLECT), a refraction layer (refrac), a high light layer (specula), a scattering layer (SSS), a caustic layer (CAUSTICS), a fog layer (ATMOSPHERE), an outer view layer (backbackground), a self-illumination layer (SELFILLUM), and the like are included, and for an element layer not depending on illumination, a DIFFUSE reflection layer (fudifse) is included.
In the embodiment of the invention, the corresponding rendering resolution ratio can be specified for the decoration scheme of the target scene, so that the rendering resolution ratio corresponding to the decoration scheme of the target scene is obtained, an offline rendering engine is called to perform (first time) offline rendering on the decoration scheme of the target scene according to the rendering resolution ratio, and the illumination-dependent element layers corresponding to the decoration scheme of the target scene are output.
And removing light in the decoration scheme of the target scene, calling an offline rendering engine to perform (second time) offline rendering on the decoration scheme of the target scene according to the rendering resolution, and outputting the element layer which does not depend on the light and corresponds to the decoration scheme of the target scene. It should be noted that, because the light is removed in the decoration scheme of the target scene, the rendering is very quick, and the rendering time is greatly reduced, so that the generation time of the decoration effect diagram can be shortened on the premise of ensuring the quality of the decoration effect diagram, the waiting time of a user is shortened, and the user experience is improved.
For example, the designer specifies a corresponding rendering resolution (1024 × 768) for the decoration scheme of the target scene, obtains the rendering resolution specified for the decoration scheme of the target scene, invokes an offline rendering engine to perform (first) offline rendering on the decoration scheme of the target scene according to the rendering resolution, and outputs illumination-dependent element layers (a global illumination layer (RAWGI), a reflection layer (REFLECT), a refraction layer (refrac), a highlight layer (specula), a scattering layer (SSS), a caustic layer (CAUSTICS), a fog layer (atmoshere), an exterior layer (backtrack), and a self-luminous layer (self).
Removing light in the decoration scheme of the target scene, calling an offline rendering engine to perform (second time) offline rendering on the decoration scheme of the target scene according to the rendering resolution (1024 × 768), and outputting an element layer (DIFFUSE reflection layer (DIFFFUSE)) which does not depend on illumination and corresponds to the decoration scheme of the target scene.
In addition, in order to further reduce rendering time, shorten generation time of the decoration effect graph, shorten user waiting time, and improve user experience, as shown in fig. 2, an implementation flow diagram of the method for outputting each element layer depending on illumination corresponding to the decoration scheme provided by the embodiment of the present invention is executed by a processor, and specifically may include the following steps:
s201, reducing the dimension of the rendering resolution ratio based on a preset resolution ratio dimension reduction strategy to obtain the rendering resolution ratio after dimension reduction.
In the embodiment of the invention, the rendering resolution corresponding to the decoration scheme of the target scene is reduced based on the preset resolution dimension reduction strategy, so that the rendering resolution after dimension reduction can be obtained.
For example, based on a preset resolution dimension reduction strategy, dimension reduction is performed on rendering resolution (1024 × 768) corresponding to the decoration scheme of the target scene, that is, the length and width of the rendering resolution are respectively reduced by 1/2, so as to obtain the rendering resolution (512 × 384) after dimension reduction.
It should be noted that, for the preset resolution dimension reduction strategy, it may be specifically set according to actual needs, for example, the length and width of the rendering resolution are respectively reduced by 1/2, 1/3, or 1/4, and the embodiment of the present invention does not limit this. Of course, it is preferable to render 1/2 each resolution length and width reduction, where the amount of rendering time reduction is better.
S202, performing off-line rendering on the decoration scheme according to the rendering resolution ratio after dimension reduction, and outputting each element layer which depends on illumination and corresponds to the decoration scheme.
After the rendering resolution corresponding to the decoration scheme of the target scene is reduced in dimension, an offline rendering engine is called to perform (first time) offline rendering on the decoration scheme of the target scene according to the rendering resolution after dimension reduction, and each element layer which depends on illumination and corresponds to the decoration scheme of the target scene is output.
For example, after the rendering resolution (1024 × 768) corresponding to the decoration scheme of the target scene is reduced, an offline rendering engine is called to perform (first) offline rendering on the decoration scheme of the target scene according to the rendering resolution (512 × 384) after the dimension reduction, and illumination-dependent element layers (a global illumination layer (RAWGI), a reflection layer (reflex), a refraction layer (refrac), a highlight layer (specula), a scattering layer (SSS), a caustic layer (CAUSTICS), a fog layer (ATMOSPHERE), an exterior layer (backround), and a self-luminous layer (selfium)) corresponding to the decoration scheme of the target scene are output.
It should be noted that, because the rendering resolution of the target scene is reduced in dimension, and the decoration scheme of the target scene is rendered offline according to the rendering resolution after the dimension reduction, the rendering time is further greatly reduced, so that the generation time of the decoration effect graph is further shortened, the user waiting time is shortened, and the user experience is improved.
S102, dividing each element layer depending on illumination into a first element layer and a second element layer.
In the embodiment of the present invention, for each element layer depending on illumination corresponding to the decoration scheme of the target scene, each element layer depending on illumination may be divided into a first type element layer and a second type element layer.
Wherein the first type element layers may comprise a reflection layer (REFLECT), a refraction layer (refrac), a highlight layer (SPECULAR), a scattering layer (SSS), a caustic layer (CAUSTICS), a haze layer (ATMOSPHERE), a BACKGROUND layer (BACKGROUND), a self-luminescence layer (selllum), and the second type element layers comprise a global illumination layer (RAWGI).
S103, processing the first element layer to obtain a target mixed layer, and processing the second element layer and the element layer not depending on illumination to obtain a target element layer.
In the embodiment of the present invention, for the first-type element layer, a target mixed layer may be obtained by processing the first-type element layer. The first-type element layers can be sequentially subjected to linear attenuation superposition to obtain a target mixed layer with rendering resolution.
For example, a reflection layer (reflex), a refraction layer (refrac), a highlight layer (SPECULAR), a scattering layer (SSS), a caustic layer (CAUSTICS), a haze layer (ATMOSPHERE), an exterior layer (backscenery), and a self-luminescence layer (selfium) are linearly subtracted and superimposed in sequence to obtain a target mixed layer (MIX) with a rendering resolution.
If the offline rendering engine is called to perform (first) offline rendering on the decoration scheme of the target scene according to the rendered resolution after the dimension reduction, and each element layer which depends on illumination and corresponds to the decoration scheme of the target scene is output, at this time, the first element layer is the first element layer of the rendered resolution after the dimension reduction, the first element layer needs to be sequentially subjected to linear attenuation and superposition to obtain a mixed layer, and the mixed layer is subjected to super-resolution amplification to obtain a target mixed layer of the rendered resolution. Thus, resolution is restored by super-division amplification.
For example, as shown in fig. 3, a reflection layer (REFLECT), a refraction layer (refrac), a highlight layer (SPECULAR), a scattering layer (SSS), a caustic layer (CAUSTICS), a fog layer (ATMOSPHERE), an exterior layer (backscenery), and a self-luminescence layer (self) are sequentially subjected to linear subtraction and superposition to obtain a mixed layer (MIX), and the mixed layer (MIX) is subjected to super-resolution amplification to obtain a target mixed layer (MIX-D) with a rendering resolution.
In addition, in the embodiment of the present invention, for the second type element layer and the element layer that does not depend on illumination and corresponds to the decoration scheme of the target scene, the second type element layer and the element layer that does not depend on illumination are processed to obtain the target element layer. And performing positive superposition on the second type element layer and the element layer not depending on illumination to obtain a target element layer with rendering resolution.
For example, the global illumination layer (RAWGI) and the DIFFUSE reflection layer (DIFFUSE) are subjected to positive film superposition to obtain a target element layer with rendering resolution, that is, a global illumination layer (GI-D) with DIFFUSE reflection.
If the offline rendering engine is called to perform (first) offline rendering on the decoration scheme of the target scene according to the rendering resolution after dimension reduction, and each element layer which depends on illumination and corresponds to the decoration scheme of the target scene is output, at this time, the second element layer is the second element layer of the rendering resolution after dimension reduction, the second element layer needs to be subjected to super-differential amplification to obtain a middle element layer of the rendering resolution, and the middle element layer and the element layer which does not depend on illumination are subjected to positive superposition to obtain the target element layer.
For example, as shown in fig. 4, the global illumination layer (RAWGI) is subjected to super-division amplification to obtain a middle element layer with a rendering resolution, that is, a new global illumination layer (RAWGI-D), and the middle element layer (the new global illumination layer (RAWGI-D)) and the DIFFUSE reflection layer (DIFFUSE) are subjected to positive film superposition to obtain a target element layer with a rendering resolution, that is, a global illumination layer with DIFFUSE reflection (GI-D).
And S104, generating a decoration effect map of the decoration scheme based on the target mixed layer and the target element layer.
For the target mixed layer and the target element layer, the decoration effect map of the decoration scheme of the target scene is generated based on the target mixed layer and the target element layer. And performing linear attenuation superposition on the target mixed layer and the target element layer to generate a decoration effect diagram of a decoration scheme of a target scene.
For example, as shown in fig. 5, a final decoration effect map (COLOR-D) of the rendering resolution is obtained by linearly reducing and superimposing the target mixed layer (MIX-D) of the rendering resolution and the target element layer (GI-D) of the rendering resolution, that is, the global illumination layer (GI-D) with diffuse reflection.
According to the technical scheme provided by the embodiment of the invention, the decoration scheme of the target scene is obtained, the decoration scheme is subjected to off-line rendering, the illumination-dependent element layers and the illumination-independent element layers corresponding to the decoration scheme are generated, the illumination-dependent element layers are divided into the first element layer and the second element layer, the first element layer is processed to obtain the target mixed layer, the second element layer and the illumination-independent element layers are processed to obtain the target element layer, and the decoration effect graph of the decoration scheme is generated based on the target mixed layer and the target element layer.
The decoration scheme of the target scene is rendered in an off-line mode, the element layers which depend on illumination and the element layers which do not depend on illumination and correspond to the decoration scheme are generated, the decoration effect graph of the decoration scheme is obtained by layer processing and layer combining, the time consumed for rendering the element layers which do not depend on illumination is short, the time consumed for generating the decoration effect graph can be shortened on the premise that the quality of the decoration effect graph is guaranteed, the user waiting time is shortened, and the user experience is improved.
