\f2stride\fP
|
||
|
|
Specifies the offset in bytes between each aggregate array element.
|
||
|
|
.SH DESCRIPTION
|
||
|
|
\%\f3glInterleavedArrays\fP 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.
|
||
|
|
.P
|
||
|
|
If \f2stride\fP is 0, the aggregate elements are stored consecutively.
|
||
|
|
Otherwise, \f2stride\fP bytes occur between the beginning of one
|
||
|
|
aggregate array element and the beginning of the next aggregate array
|
||
|
|
element.
|
||
|
|
.P
|
||
|
|
\f2format\fP serves as a ``key''
|
||
|
|
describing the extraction of individual arrays from the aggregate array.
|
||
|
|
If \f2format\fP 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.
|
||
|
|
.P
|
||
|
|
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.
|
||
|
|
.SH NOTES
|
||
|
|
\%\f3glInterleavedArrays\fP is available only if the GL version is 1.1 or greater.
|
||
|
|
.P
|
||
|
|
If \%\f3glInterleavedArrays\fP is called while compiling a display list, it is not
|
||
|
|
compiled into the list, and it is executed immediately.
|
||
|
|
.P
|
||
|
|
Execution of \%\f3glInterleavedArrays\fP is not allowed between the execution of
|
||
|
|
\%\f3glBegin\fP and the corresponding execution of \%\f3glEnd\fP,
|
||
|
|
but an error may or may not be generated. If no error is generated,
|
||
|
|
the operation is undefined.
|
||
|
|
.P
|
||
|
|
\%\f3glInterleavedArrays\fP is typically implemented on the client side.
|
||
|
|
.P
|
||
|
|
Vertex array parameters are client-side state and are therefore not
|
||
|
|
saved or restored by \%\f3glPushAttrib\fP and \%\f3glPopAttrib\fP.
|
||
|
|
Use \%\f3glPushClientAttrib\fP and \%\f3glPopClientAttrib\fP instead.
|
||
|
|
.P
|
||
|
|
When the \%\f3GL_ARB_multitexture\fP extension is supported, \%\f3glInterleavedArrays\fP
|
||
|
|
only updates the texture coordinate array for the active active texture
|
||
|
|
unit. The texture coordinate state for other client texture units is not
|
||
|
|
update, regardless if they are enabled or not.
|
||
|
|
.SH ERRORS
|
||
|
|
\%\f3GL_INVALID_ENUM\fP is generated if \f2format\fP is not an accepted value.
|
||
|
|
.P
|
||
|
|
\%\f3GL_INVALID_VALUE\fP is generated if \f2stride\fP is negative.
