[简单教程]在blender里编写自己的着色器

 1 shader test(float Kd=1,
 2 float Exponent = 10.0,
 3 color Col=1,
 4 color Color1 = color(0.8, 0.0, 0.0),
 5     color Color2 = color(0.0, 0.8, 0.0),
 6     color Color3 = color(0.0, 0.0, 0.8),
 7     color Color4 = 0.1,
 8     color Color5 = 0.2,
 9     color Color6 = 0.3,
10     color Color7 = 0.4,
11     color Color8 = 0.5,
12 normal Normal=N,
13 output closure color Phong = 0,//冯氏光照模型
14 output closure color Diffuse=0//漫反射光照模型)
15 {
16   color Color[8] = {Color1, Color2, Color3, Color4, Color5, Color6, Color7, Color8};
17   Diffuse = Kd*Col*diffuse(Normal);
18   Phong=phong_ramp(Normal,Exponent,Color);
19 }
