NAME
glInterleavedArrays - simultaneously specify and enable
several interleaved arrays
C SPECIFICATION
void glInterleavedArrays( GLenum format,
GLsizei stride,
const GLvoid *pointer )
PARAMETERS
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 aggre-
gate array element.
DESCRIPTION
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 implemen-
tations, this is more efficient than specifying the arrays
separately.
If stride is 0, the aggregate elements are stored consecu-
tively. 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 con-
tains 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
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 there-
fore not saved or restored by glPushAttrib and glPopAttrib.
Use glPushClientAttrib and glPopClientAttrib instead.
When the GL_ARB_multitexture extension is supported,
glInterleavedArrays only updates the texture coordinate
array for the active active texture unit. The texture coor-
dinate state for other client texture units is not update,
regardless if they are enabled or not.
ERRORS
GL_INVALID_ENUM is generated if format is not an accepted
value.
GL_INVALID_VALUE is generated if stride is negative.
