Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] 2D vector graphics use basic primitives such as points, line segments, arcs, polygons, and irregular curves to describe vector graphics, and then determine the display of graphics by specifying the drawing line width, connection line shape, filling mode, and coloring style of the basic primitives Effect. In the GPU pipeline, the 3D model is rendered by defining the index, position, normal, texture coordinates, texture, etc. of the triangle vertices, while the GPU-based 2D vector graphics rendering method utilizes the characteristics of modern GPU programmable pipelines and powerful parallel data processing Ability to use GPU shaders to process most of the process of vector graphics, greatly reducing CPU load, seamlessly integrated into the 3D pipeline, greatly improving rendering efficiency, and in order to maximize rendering efficiency ...

Description

technical field [0001] The present invention relates to the field of image processing, more specifically, it relates to a GPU-based efficient 2D vector graphics rendering method. Background technique [0002] Vector graphics are used in computer graphics to represent images based on mathematical equations such as points, lines, and polygons. They are widely used in industrial graphic design, game video special effects, and word processing. Due to the complexity of the vector graphics primitive itself, CPU rasterization algorithms are mostly used for its rendering. In order to improve drawing efficiency, existing 2D rendering engines such as Skia and Cario use algorithms combining CPU and GPU to perform triangulation on vector graphics elements in the CPU, and then use GPU for rendering. However, the CPU load of this method is still relatively large. NVidia Corporation proposed a CUDA-based 2D vector path rendering method, but due to the hardware specificity required by the...
