Problems solved by technology

At present, most of the 3D stylized rendering systems mainly rely on the CPU for calculation, and can achieve real-time rendering for some simple painting effects, but cannot achieve real-time rendering for more expressive and complex painting effects, resulting in many complex stylized renderings that cannot be applied to 3D stylized games and 3D stylized virtual environment roaming and other real-time occasions

Embodiment Construction

[0048] A system for implementing the method of the present invention, such as figure 1 As shown, it includes: 3D object model input interface 100, stylized texture library 110, classification object rendering 120, graphics processing unit (GPU) 130 and animation video output 140, wherein, classification object rendering 120 includes mountain rendering 121, sea of ​​clouds rendering 122, 123 for waterfall rendering, 124 for tree rendering.

[0049] The process flow of the three-dimensional ink effect rendering method based on the graphics processor of the present invention is as follows: figure 2 As shown, the process follows the following steps in turn:

[0050] 1. Use the input command to input the scene model and ink style texture library;

[0051] 2. Multi-layer ink style mountain rendering based on ink style texture array;

[0052] 3. Ink-style cloud sea rendering based on displacement mapping method;

[0053] 4. Ink style waterfall rendering based on texture motion m...

Abstract

The present invention discloses 3D ink and wash effect rendering method based on graphic processor. Graphic processor is utilized to provide programmable streamline for classifying common objects in Chinese landscape painting. The ink and wash effect rendering method for multipeaked mountain, cloud sea, waterfall and trees is proposed to realize the motion of dynamic objects, such as cloud sea and waterfall, in scene and the treatment of the boundary between dynamic object and static object. The method of the present invention maintains the ink and wash style characteristic of the said objects in 3D environment effectively, expresses the motion of dynamic objects and reaches real-time rendering effect.

Description

technical field [0001] The invention relates to a graphics rendering, in particular to a three-dimensional ink effect rendering method of a Graphics Processing Unit (GPU). Background technique [0002] The purpose of 3D stylized rendering is to render the 3D model into a hand-painted effect, which has wide application value in the fields of animation and games. At present, most of the 3D stylized rendering systems mainly rely on the CPU for calculation, and can achieve real-time rendering for some simple painting effects, but cannot achieve real-time rendering for more expressive and complex painting effects, resulting in many complex stylized renderings that cannot be applied to 3D stylized games and 3D stylized virtual environment roaming and other real-time occasions. In the field of animation production, it currently takes an average of 10 minutes to render a picture. If real-time rendering can be performed, the efficiency of animation rendering can be greatly improved ...
