NAME
       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);  1.1 )


PARAMETERS
       1.1  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);  1.1 )


PARAMETERS
       1.1    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.
