glInterleavedArrays(3G) OpenGL Reference glInterleavedArrays(3G)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 aggregate 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 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
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
GL_INVALID_ENUM is generated if format is not an accepted value.
GL_INVALID_VALUE is generated if stride is negative.
