The glVertexAttribPointer() command was briefly introduced in Chapter 1. The prototype is as follows:

void glVertexAttribPointer(GLuint index, GLint size,                         GLenum type, GLboolean normalized,                         GLsizei stride, const GLvoid *pointer);

Specifies where the data values for the vertex attribute with location index can be accessed. pointer is the offset in basic-machine units (i.e., bytes)from the start of the buffer object currently bound to the GL_ARRAY_BUFFER target for the first set of values in the array. size represents the number of components to be updated per vertex. type specifies the data type of each element in the array. normalized indicates that the vertex data ...
