class SGFXAPI::IndexBuffer

The IndexBuffer (IBO) actually represents the index data array sent to the GPU.

  • The array is simply a list of integers.
  • The size of the integers is one of {8,16,32} bits; it can be chosen in the constructor.
  • Each integer is an index into the VBOs of the mesh.
  • In the most usual case, the mesh is a triangle mesh, and the IBO represents a series of triangles; in this case, every 3 indices is another triangle.
