基于几何着色器的三角形网格细分实现

Implementation of Triangle Subdivision Based on Geometry Shader

针对基于几何着色器进行三角形的网格细分的问题，分析了几何着色器的作用和使用方法，给出了利用参数化坐标方法对三角形进行任意细节水平细分的过程。以由8个三角形组成的多边形细分成球为例，通过实验验证了整个方法的正确性。本文的研究为下一步几何着色器在具体研究领域的应用打下了基础。

Aimed to triangle subdivision based on geometry shader, the principle and using method of geometry shader was analyzed in detail. It give the process which use way of the parametric coordinates to horizontal subdivided Triangle to any level of detail, take the process of sphere subdivision with 8 triangles polygons for example, the way which was verified by experiment is right. The result laid the foundation for Geometry shader application in specific field of the next step.
