patch TinyRenderer so it software-renders in an OpenGL texture, for testing fix texture support: flip texture to make OpenGL happy (lower-left is origin) add path prefix to .obj loader, so materials/textures are loaded ok. 2016-04-27 03:52:52 +00:00

make some changes to make the previous example code changes backward compatible 2016-08-12 21:18:46 +00:00			`void triangle(mat<4,3,float> &pts, IShader &shader, TGAImage &image, float *zbuffer, const Matrix& viewPortMatrix);`
add segmentation mask rendering to TinyRenderer and shared memory API similar to the zbuffer, but storing the object index (int) instead of float depth 2016-08-11 21:55:30 +00:00			`void triangle(mat<4,3,float> &pts, IShader &shader, TGAImage &image, float zbuffer, int segmentationMaskBuffer, const Matrix& viewPortMatrix, int objectIndex);`
