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 aggre-
              gate 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 implemen-
     tations, this is more efficient than specifying the arrays
     separately.

     If stride is 0, the aggregate elements are stored consecu-
     tively. 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 con-
     tains 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 there-
     fore 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 coor-
     dinate 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.
