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
