Abstract

The invention discloses a GPU acceleration-based dynamic light effect realizing method and a GPU acceleration-based dynamic light effect realizing system. The method includes the following steps that: cone light beam textures in space are mapped into a texture spatial coordinate system, so that corresponding first geometric primitives can be obtained; under the clamp mode of the texture spatial coordinate system, the original point of the texture spatial coordinate system is shifted, so that a corresponding relative texture coordinate system is built, and the first geometric primitives are mapped into the relative texture coordinate system, so that second geometric primitives can be obtained; and after vector angle judgment is performed on the second geometric primitives, region filling drawing is carried out, and the dynamic volume rendering of a cone light beam is realized through GPU-multi thread acceleration. According to the GPU acceleration-based dynamic light effect realizing method and the GPU acceleration-based dynamic light effect realizing system, through a GPU-multi thread acceleration mode, the rendering of dynamic volume light is realized, an original rendering mode of dynamic volume light is improved, the burden of a CPU can be decreased, and the concurrent advantage of a GPU is utilized, the balance of the CPU and the GPU is achieved, and great conveniences can be brought about.

Description

technical field [0001] The present invention relates to the field of 3D display, in particular to a method and system for realizing dynamic light effects based on GPU acceleration. Background technique [0002] Generally speaking, in 3D UI and 3D games, real-time dynamic light and shadow effects can increase the realism of 3D scenes and improve the display effect. The volumetric light implementation based on OpenGL ES1.0 achieves dynamic volumetric light by first slicing the cone, and then adding a light map to the surface, but this rendering method will greatly increase the number of drawn triangles and consume CPU resources. resulting in a drop in frame rate. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a dynamic light effect realization method and system based on GPU acceleration, aiming at solving the problem that the existing dy...
