fglIndex(3G)		       OpenGL Reference			  fglIndex(3G)

NAME
     fglIndexd, fglIndexf, fglIndexi, fglIndexs, fglIndexub, fglIndexdv,
     fglIndexfv, fglIndexiv, fglIndexsv, fglIndexubv - set the current color
     index

FORTRAN SPECIFICATION
     SUBROUTINE fglIndexd( REAL*4 c )
     SUBROUTINE fglIndexf( REAL*4 c )
     SUBROUTINE fglIndexi( INTEGER*4 c )
     SUBROUTINE fglIndexs( INTEGER*2 c )
     SUBROUTINE fglIndexub( INTEGER*1 c )

PARAMETERS
     c	Specifies the new value for the current color index.

FORTRAN SPECIFICATION
     SUBROUTINE fglIndexdv( CHARACTER*8 c )
     SUBROUTINE fglIndexfv( CHARACTER*8 c )
     SUBROUTINE fglIndexiv( CHARACTER*8 c )
     SUBROUTINE fglIndexsv( CHARACTER*8 c )
     SUBROUTINE fglIndexubv( CHARACTER*256 c )

PARAMETERS
     c	  Specifies a pointer to a one-element array that contains the new
	  value for the current color index.

DESCRIPTION
     fglIndex updates the current (single-valued) color index.	It takes one
     argument, the new value for the current color index.

     The current index is stored as a floating-point value. Integer values are
     converted directly to floating-point values, with no special mapping.
     The initial value is 1.

     Index values outside the representable range of the color index buffer
     are not clamped.  However, before an index is dithered (if enabled) and
     written to the frame buffer, it is converted to fixed-point format.  Any
     bits in the integer portion of the resulting fixed-point value that do
     not correspond to bits in the frame buffer are masked out.

NOTES
     fglIndexub and fglIndexubv are available only if the GL version is 1.1 or
     greater.

     The current index can be updated at any time.  In particular, fglIndex
     can be called between a call to fglBegin and the corresponding call to
     fglEnd.
