glInterleavedArrays — simultaneously specify and enable several interleaved arrays
|const GLvoid *||pointer|
Specifies the type of array to enable. Symbolic constants
Specifies the offset in bytes between each aggregate array element.
glInterleavedArrays lets you specify and enable individual color,
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
stride is 0, the aggregate elements are stored consecutively.
stride bytes occur between the beginning of one
aggregate array element and the beginning of the next aggregate array
format serves as a ``key''
describing the extraction of individual arrays from the aggregate array.
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.
glInterleavedArrays is available only if the GL version is 1.1 or greater.
glInterleavedArrays is called while compiling a display list, it is not
compiled into the list, and it is executed immediately.
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.
For OpenGL versions 1.3 and greater, or when the
ARB_multitexture extension is supported,
only updates the texture coordinate array for the client active texture
unit. The texture coordinate state for other client texture units is not
updated, regardless of whether the client texture unit is enabled or not.
Secondary color values are not supported in interleaved vertex array formats.
GL_INVALID_ENUM is generated if
format is not an accepted value.
GL_INVALID_VALUE is generated if
stride is negative.
