Embodiment Construction

[0037] Below in conjunction with accompanying drawing, the present invention will be further described with regard to specific embodiment:

[0038] Such as figure 1 As shown, a kind of VRAY-based PBR material rendering method provided by the present invention includes:

[0039] Step 101: Model grouping preprocessing, automatically grouping processing according to the material information and surface area of ​​the model; the main purpose of model grouping is to ensure that the number of objects in each group is not too large, so as to ensure the clarity of the texture in each group Spend.

[0040] Step 101 also includes grouping transparent and opaque objects. Since transparent and non-transparent objects have different processing logics when displayed on the front end, it is first necessary to group transparent and opaque objects according to the model material.

[0041] The non-transparent objects filtered out according to the model's transparency attribute need to be group...

Abstract

The invention discloses a PBR material rendering method and system based on VRAY. The method comprises the steps that 1, model grouping preprocessing; 2, model light weight and UV expansion; 3, bakingthe PBR material; 4, double UV channel display; 5, compressing materials, including model compression and material compression; 6, a KSF description file; and 7, entering a PBR rendering system for real-time rendering. The invention has the advantages that Max model design files and Vray rich material systems can be efficiently and accurately converted into models capable of being displayed in WebGL in real time in a short time, the 3D real-time rendering application speed is high, and the requirements for used equipment and operating systems are reduced. According to the front-end real-timePBR rendering system, the real-time rendering effect close to the off-line rendering effect is truly displayed, the material effect is accurately expressed, and the realistic degree of 3D real-time rendering of the model is improved; the method solves the problems that traditional material baking cannot support tiled textures, and patterns are blurred when details are magnified and viewed.

Description

technical field [0001] The invention relates to the technical field of home decoration design rendering, in particular to a VRAY-based PBR material rendering method and system. Background technique [0002] In the fields of interior decoration, retail goods, furniture goods, etc., 3DsMax and VRay materials and VRay offline renderer are mostly used for the design of 3D digital models. The design model and material data based on VRay offline rendering are used for offline rendering of photos and renderings, such as posters, albums, advertisements, etc. With the popularity of digitization and virtualization applications, there are more and more applications for 3D real-time rendering of digital models, especially in mobile applications, web applications, and small applications based on Web browser technology. However, such model data cannot be directly used for 3D real-time rendering, such as 3D display and browsing. [0003] There are two main reasons. First, the material sy...
