41 * vertex buffer objects.

45 * \param elementSize size of each array element, in bytes
46 * \param size components per element (1, 2, 3 or 4)
47 * \param type datatype of each component (GL_FLOAT, GL_INT, etc)
48 * \param stride stride between elements, in elements
49 * \param normalized are integer types converted to floats in [-1, 1]?
50 * \param ptr the address (or offset inside VBO) of the array data
