openGL shade

opengl에서 지원하는 쉐이드(면 색상 칠하기)는 flat과 gouraud 뿐이라는데

한 20년 전에 퐁은 어떻게 한거였지?

 

I digged around a bit. You can use the fixed function pipeline and set glLightModeli(GL_LIGHT_MODEL_TWO_SIDE, 1); GL will then light backfaces with your back material and reversed normals.

flat / Gouraud

phong은 쉐이더 써야한다고
