a project which introduction to SphericalHarmonicLighting in Game using Unity

about project data: I use stanford dragon as model which has 5000 vertecies and 10000 faces. I use some cubemap as light source.

about project operator: you can move mouse to rotate light source and press to backspace to change a light source in run-time. you can change the value of CoffeeSHPath on SHRender1 Component to watch the different about self-shadow and InterReflection.

about project Scripts: coffeeSHIntegrator : these part pre-Compute DiffuseWithShadow-SH Light tranfer Function Integrator. InterReflection : these part pre-Compute InterReflection-SH Light tranfer Function Integrator. LightSHIntegrator : these part pre-Compute Light Source Integrator. SHRender.cs & SHRender.shader : Run-time Render SH with CPU. SHRender1.cs & SHRender1.shader: Run-time Render SH with GPU and ps-part.

一个用于介绍球谐光照原理的Unity项目。

数据： 模型使用的斯坦福龙，光源是不同的cubemap。

操作： 你可以移动鼠标来移动光源，按下空格切换一个光源。 你可以修改SHRender1 组件下 CoffeeSHPath 的路径 (dragon.txt or dragonInterReflection.txt) 来观看自阴影和内反射的不同。

脚本： coffeeSHIntegrator.cs: 用于Diffuse&自阴影效果的光照传输函数的预计算积分 InterReflection.cs:用于内反射效果的光照传输函数的预计算积分 LightSHIntegrator.cs:用于光源的预计算积分 SHRender：在CPU的SH实时渲染 SHRender1：在GPU端的SH实时渲染
