void <STRONG>glIndexfv</STRONG>( const GLfloat *<EM>c</EM> )
void <STRONG>glIndexiv</STRONG>( const GLint *<EM>c</EM> )
void <STRONG>glIndexsv</STRONG>( const GLshort *<EM>c</EM> )
void <STRONG>glIndexubv</STRONG>( const GLubyte *<EM>c</EM> )
<STRONG>PARAMETERS</STRONG>
<EM>c</EM> Specifies a pointer to a one-element array that
contains the new value for the current color index.
<STRONG>DESCRIPTION</STRONG>
<STRONG>glIndex</STRONG> 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.
<STRONG>NOTES</STRONG>
<STRONG>glIndexub</STRONG> and <STRONG>glIndexubv</STRONG> are available only if the GL
version is 1.1 or greater.
The current index can be updated at any time. In
particular, <STRONG>glIndex</STRONG> can be called between a call to <STRONG>glBegin</STRONG>
and the corresponding call to <STRONG>glEnd</STRONG>.
