Model rendering method, device and equipment

Abstract

Embodiments of the invention provide a model rendering method, apparatus and device. The method comprises the steps of obtaining a hand-drawn natural color map, a normal map and a two-dimensional light and shadow image of a target object, wherein the two-dimensional light and shadow image carries light and shadow information of a target object; combining the two-dimensional light and shadow imagewith the hand-painted natural color map to obtain a target natural color map of the target object; and outputting the target intrinsic color map and the normal map to render a three-dimensional modelof the target object. According to the method, the light and shadow information is directly added into the target inherent color map through combination of the two-dimensional light and shadow image and the hand-painted inherent color map, so that the target inherent color map replaces a Metallic map or a Specular map in the current PRB manufacturing process, the map acquisition efficiency can beimproved, and the performance requirement of the rendering process on equipment can be reduced; the rendering efficiency of the three-dimensional model is improved, and the application range of the chartlet is expanded. Through the target natural color chartlet, the display picture of the three-dimensional model can be prevented from being influenced by the PBR effect.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a model rendering method, device and equipment. Background technique [0002] Physically Based Rendering (Physically Based Rendering, PBR) technology is a rendering technology based on micro-surface objects. Because of its outstanding performance in simulating light reflection, PBR technology is often used in various advanced games and film and television productions. [0003] At present, there are two main workflows for making PBR textures according to the type of texture, namely Metallic-based workflow and Specular-based workflow. No matter what kind of workflow, it needs to go through modeling, output normal map, intrinsic color map, draw roughness (Roughness) map, Metallic map or Specular map according to intrinsic color map and other steps. According to the physical information provided by these maps, shadows, highlights, reflections, and Fresnel effects c...

AI Technical Summary

Problems solved by technology

However, at present, the workflow of producing 3D scenes using PBR technology is long, the resource consumption is large, and the scene production efficiency is low.

[0004] In addition, the textures of 3D scenes produced by PBR technology cannot be adapted to all devices

For devices with low-end performance, a large number of PBR textures will cause the display speed of the 3D scene to be slow, and even the rendering cannot be loaded.

If you stop using the PBR effect, the display scene will be relatively flat, and the visual difference from the 3D scene using the PBR effect will be too large
