GLINDEX(3G)			 OpenGL Manual			   GLINDEX(3G)

NAME
       glIndex - set the current color index

C SPECIFICATION
       void glIndexs(GLshort c);

       void glIndexi(GLint c);

       void glIndexf(GLfloat c);

       void glIndexd(GLdouble c);

       void glIndexub(GLubyte c);

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

C SPECIFICATION
       void glIndexsv(const GLshort * c);

       void glIndexiv(const GLint * c);

       void glIndexfv(const GLfloat * c);

       void glIndexdv(const GLdouble * 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 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
       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
