NAME    [Toc]    [Back]

     glInterleavedArrays - simultaneously specify and enable several
     interleaved arrays

C SPECIFICATION    [Toc]    [Back]

     void glInterleavedArrays( GLenum format,
			       GLsizei stride,
			       const GLvoid *pointer )

PARAMETERS    [Toc]    [Back]

     format   Specifies	the type of array to enable. Symbolic constants
	      GL_V2F, GL_V3F, GL_C4UB_V2F, GL_C4UB_V3F,	GL_C3F_V3F,
	      GL_N3F_V3F, GL_C4F_N3F_V3F, GL_T2F_V3F, GL_T4F_V4F,
	      GL_T2F_C4UB_V3F, GL_T2F_C3F_V3F, GL_T2F_N3F_V3F,
	      GL_T2F_C4F_N3F_V3F, and GL_T4F_C4F_N3F_V4F are accepted.

     stride   Specifies	the offset in bytes between each aggregate array
	      element.

DESCRIPTION    [Toc]    [Back]

     glInterleavedArrays lets you specify and enable individual	color, normal,
     texture and vertex	arrays whose elements are part of a larger aggregate
     array element.  For some implementations, this is more efficient than
     specifying	the arrays separately.

     If	stride is 0, the aggregate elements are	stored consecutively.
     Otherwise,	stride bytes occur between the beginning of one	aggregate
     array element and the beginning of	the next aggregate array element.

     format serves as a	``key''	describing the extraction of individual	arrays
     from the aggregate	array.	If format contains a T,	then texture
     coordinates are extracted from the	interleaved array.  If C is present,
     color values are extracted. If N is present, normal coordinates are
     extracted.	 Vertex	coordinates are	always extracted.

     The digits	2, 3, and 4 denote how many values are extracted.  F indicates
     that values are extracted as floating-point values.  Colors may also be
     extracted as 4 unsigned bytes if 4UB follows the C.  If a color is
     extracted as 4 unsigned bytes, the	vertex array element which follows is
     located at	the first possible floating-point aligned address.

NOTES    [Toc]    [Back]

     glInterleavedArrays is available only if the GL version is	1.1 or
     greater.

     If	glInterleavedArrays is called while compiling a	display	list, it is
     not compiled into the list, and it	is executed immediately.

     Execution of glInterleavedArrays 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.

     glInterleavedArrays 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    [Toc]    [Back]

     GL_INVALID_ENUM is	generated if format is not an accepted value.

     GL_INVALID_VALUE is generated if stride is	negative.
