In the lecture slides, we saw the following code to draw a buffer in modern OpenGL:glDrawElements(PrimType[object], NumElems[object], GL_UNSIGNED_BYTE, BUFFER_OFFSET(0)) ;The third argument to glDrawElements denotes the type of the vertex indices.Given our code as is, how many unique vertices can be referenced by each face?______
