GLINDEXPOINTER(3G)			  OpenGL Manual 		       GLINDEXPOINTER(3G)

NAME
       glIndexPointer - define an array of color indexes

C SPECIFICATION
       void glIndexPointer(GLenum type, GLsizei stride, const GLvoid * pointer);

PARAMETERS
       type
	   Specifies the data type of each color index in the array. Symbolic constants
	   GL_UNSIGNED_BYTE, GL_SHORT, GL_INT, GL_FLOAT, and GL_DOUBLE are accepted. The initial
	   value is GL_FLOAT.

       stride
	   Specifies the byte offset between consecutive color indexes. If stride is 0, the color
	   indexes are understood to be tightly packed in the array. The initial value is 0.

       pointer
	   Specifies a pointer to the first index in the array. The initial value is 0.

DESCRIPTION
       glIndexPointer specifies the location and data format of an array of color indexes to use
       when rendering.	type specifies the data type of each color index and stride specifies the
       byte stride from one color index to the next, allowing vertices and attributes to be
       packed into a single array or stored in separate arrays.

       If a non-zero named buffer object is bound to the GL_ARRAY_BUFFER target (see
       glBindBuffer()) while a color index array is specified, pointer is treated as a byte
       offset into the buffer object's data store. Also, the buffer object binding
       (GL_ARRAY_BUFFER_BINDING) is saved as color index vertex array client-side state
       (GL_INDEX_ARRAY_BUFFER_BINDING).

       When a color index array is specified, type, stride, and pointer are saved as client-side
       state, in addition to the current vertex array buffer object binding.

       To enable and disable the color index array, call glEnableClientState() and
       glDisableClientState() with the argument GL_INDEX_ARRAY. If enabled, the color index array
       is used when glDrawArrays(), glMultiDrawArrays(), glDrawElements(), glMultiDrawElements(),
       glDrawRangeElements(), or glArrayElement() is called.

NOTES
       glIndexPointer is available only if the GL version is 1.1 or greater.

       Color indexes are not supported for interleaved vertex array formats (see
       glInterleavedArrays()).

       The color index array is initially disabled and isn't accessed when glArrayElement(),
       glDrawElements(), glDrawRangeElements(), glDrawArrays(), glMultiDrawArrays(), or
       glMultiDrawElements() is called.

       Execution of glIndexPointer is not allowed between glBegin() and the corresponding
       glEnd(), but an error may or may not be generated. If an error is not generated, the
       operation is undefined.

       glIndexPointer is typically implemented on the client side.

       Color index array parameters are client-side state and are therefore not saved or restored
       by glPushAttrib() and glPopAttrib(). Use glPushClientAttrib() and glPopClientAttrib()
       instead.

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

       GL_INVALID_VALUE is generated if stride is negative.

ASSOCIATED GETS
       glIsEnabled() with argument GL_INDEX_ARRAY

       glGet() with argument GL_INDEX_ARRAY_TYPE

       glGet() with argument GL_INDEX_ARRAY_STRIDE

       glGet() with argument GL_INDEX_ARRAY_BUFFER_BINDING

       glGet() with argument GL_ARRAY_BUFFER_BINDING

       glGetPointerv() with argument GL_INDEX_ARRAY_POINTER
