stride Specifies the offset in bytes between each aggregate array
element.
DESCRIPTION
glInterleavedArrays lets you specify and enable individual color, nor‐
mal, texture and vertex arrays whose elements are part of a larger
aggregate array element. For some implementations, this is more effi‐
cient than specifying the arrays seperately.
If stride is 0, the aggregate elements are stored consecutively. Oth‐
erwise, 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 coordi‐
nates 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 indi‐
cates 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 fol‐
lows 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 glPushClientAt‐
trib 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.
