Document Type and Number:
WIPO Patent Application WO/2021/174659
Kind Code:
A1
Abstract:
Disclosed is a WebGL-based progressive real-time rendering method for an editable large scene, relating to the field of 3D real-time rendering. The method comprises: 1. performing hierarchical spatial relationship management based on a BVH spatial structure; and 2. performing progressive scene drawing. The beneficial effects of the present invention lie in that an original scene design model is reserved, an editable updating operation is supported, progressive rendering drawing is performed on a large three-dimensional scene, and a three-dimensional interaction real-time rendering environment is kept smooth in devices with different capacities and in scenes of different scales and sizes. In a graphics system of a KUJIALE design tool, by using the technique, a user can design and edit a large scene in a browser environment.
