基于OpenGL的等角插补明暗处理的软件实现

OpenGL based software implementation of equal angle interpolation shading

等角插补明暗处理具有Phong明暗处理的视觉效果,而且具有较Phong明暗处理更快的渲染效率,基于标准图形渲染管道,用C语言实现了OpenGL渲染管道的硬件计算部分,同时用C语言实现了等角插补明暗处理,并给出了实验结果。该方法的实现可为渲染算法的研究和实现提供参考。

Equal angle interpolation shading not only has the same visual effect as that of Phong shading,but also can get more rendering efficiency than that of Phong shading.In this paper,based on the standard graphics rendering pipeline,hardware computing of OpenGL rendering pipeline,and equal angle interpolation shading are implemented by using C language.In the final,experiments are presented.This implementation can be referenced in the research and designing of rendering algorithm.
