GLVERTEXPOINTER(3G)		 OpenGL Manual		   GLVERTEXPOINTER(3G)

NAME
       glVertexPointer - define an array of vertex data

C SPECIFICATION
       void glVertexPointer(GLint size, GLenum type, GLsizei stride,
			    const GLvoid * pointer);

PARAMETERS
       size
	   Specifies the number of coordinates per vertex. Must be 2, 3, or 4.
	   The initial value is 4.

       type
	   Specifies the data type of each coordinate in the array. Symbolic
	   constants GL_SHORT, GL_INT, GL_FLOAT, or GL_DOUBLE are accepted.
	   The initial value is GL_FLOAT.

       stride
	   Specifies the byte offset between consecutive vertices. If stride
	   is 0, the vertices are understood to be tightly packed in the
	   array. The initial value is 0.

       pointer
	   Specifies a pointer to the first coordinate of the first vertex in
	   the array. The initial value is 0.

DESCRIPTION
       glVertexPointer specifies the location and data format of an array of
       vertex coordinates to use when rendering.  size specifies the number of
       coordinates per vertex, and must be 2, 3, or 4.	type specifies the
       data type of each coordinate, and stride specifies the byte stride from
       one vertex to the next, allowing vertices and attributes to be packed
       into a single array or stored in separate arrays. (Single-array storage
       may be more efficient on some implementations; see
       glInterleavedArrays().)

       If a non-zero named buffer object is bound to the GL_ARRAY_BUFFER
       target (see glBindBuffer()) while a vertex array is specified, pointer
       is treated as a byte offset into the buffer object's data store. Also,
       the buffer object binding (GL_ARRAY_BUFFER_BINDING) is saved as vertex
       array client-side state (GL_VERTEX_ARRAY_BUFFER_BINDING).

       When a vertex array is specified, size, type, stride, and pointer are
       saved as client-side state, in addition to the current vertex array
       buffer object binding.

       To enable and disable the vertex array, call glEnableClientState() and
       glDisableClientState() with the argument GL_VERTEX_ARRAY. If enabled,
       the vertex array is used when glArrayElement(), glDrawArrays(),
       glMultiDrawArrays(), glDrawElements(), glMultiDrawElements(), or
       glDrawRangeElements() is called.

NOTES
       glVertexPointer is available only if the GL version is 1.1 or greater.

       The vertex array is initially disabled and isn't accessed when
       glArrayElement(), glDrawElements(), glDrawRangeElements(),
       glDrawArrays(), glMultiDrawArrays(), or glMultiDrawElements() is
       called.

       Execution of glVertexPointer is not allowed between the execution of
       glBegin() and the corresponding execution of glEnd(), but an error may
       or may not be generated. If no error is generated, the operation is
       undefined.

       glVertexPointer is typically implemented on the client side.

       Vertex array parameters are client-side state and are therefore not
       saved or restored by glPushAttrib() and glPopAttrib(). Use
       glPushClientAttrib() and glPopClientAttrib() instead.

ERRORS
       GL_INVALID_VALUE is generated if size is not 2, 3, or 4.

       GL_INVALID_ENUM is generated if type is not an accepted value.

       GL_INVALID_VALUE is generated if stride is negative.

ASSOCIATED GETS
       glIsEnabled() with argument GL_VERTEX_ARRAY

       glGet() with argument GL_VERTEX_ARRAY_SIZE

       glGet() with argument GL_VERTEX_ARRAY_TYPE

       glGet() with argument GL_VERTEX_ARRAY_STRIDE

       glGet() with argument GL_VERTEX_ARRAY_BUFFER_BINDING

       glGet() with argument GL_ARRAY_BUFFER_BINDING

       glGetPointerv() with argument GL_VERTEX_ARRAY_POINTER
