WebOpenGL gives us the flexibility to define our own framebuffers and thus define our own color (and optionally a depth and stencil) buffer. The rendering operations we've done so far were all done on top of the render buffers attached to the default framebuffer. WebUsing vertex normals in OpenGL To use normals in OpenGL, it’s very easy. A normal is an attribute of a vertex, just like its position, its color, its UV coordinates… so just do the usual stuff. Our loadOBJ function from Tutorial 7 already reads them from the OBJ file.
