3G
glFogCoord
set the current fog coordinates
C Specification
void glFogCoordd
GLdouble coord
void glFogCoordf
GLfloat coord
Parameters
coord
Specify the fog distance.
C Specification
void glFogCoorddv
GLdouble * coord
void glFogCoordfv
GLfloat * coord
Parameters
coord
Specifies a pointer to an array containing a single value representing the
fog distance.
Description
glFogCoord specifies the fog coordinate that is associated with each vertex and
the current raster position. The value specified is interpolated and used
in computing the fog color (see glFog).
Notes
glFogCoord is available only if the GL version is 1.4 or greater.
The current fog coordinate can be updated at any time. In particular,
glFogCoord can be called between a call to glBegin and the corresponding
call to glEnd.
