       glIndexd,,  glIndexf,,  glIndexi,,  glIndexs,,  glIndexub,, glIndexdv,, glIn-
       dexfv,, glIndexiv,, glIndexsv,, glIndexubv - set the current color index



C SPECIFICATION
       void glIndexd( GLdouble c )
       void glIndexf( GLfloat c )
       void glIndexi( GLint c )
       void glIndexs( GLshort c )
       void glIndexub( GLubyte c )


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


C SPECIFICATION
       void glIndexdv( const GLdouble *c )
       void glIndexfv( const GLfloat *c )
       void glIndexiv( const GLint *c )
       void glIndexsv( const GLshort *c )
       void glIndexubv( const GLubyte *c )


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

DESCRIPTION
       glIndex  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 map-
       ping.  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 .  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
       glIndexub and glIndexubv are available only if the GL version is 1.1 or
       greater.

       The  current  index can be updated at any time.  In particular, glIndex
       can be called between a call to glBegin and the corresponding  call  to
       glEnd.
