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 coor-dinates coordinates
       dinates 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 correspond-ing corresponding
       ing execution of glEnd, but an error may or may not be generated. If no error is generated, the oper-ation operation
       ation 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.

       When the GL_ARB_multitexture extension is supported, glInterleavedArrays  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.

ERRORS
       GL_INVALID_ENUM is generated if format is not an accepted value.

       GL_INVALID_VALUE is generated if stride is negative.
