GLINDEX(3G)                                                                                      GLINDEX(3G)



NAME
       glIndexd,  glIndexf, glIndexi, glIndexs, glIndexub, glIndexdv, glIndexfv, glIndexiv, glIndexsv, glIn-dexubv glIndexubv
       dexubv - 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 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 fixedpoint
       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.

ASSOCIATED GETS
       glGet with argument GL_CURRENT_INDEX
