setdepth(3G) setdepth(3G)
NAME
setdepth - sets up a 3-D viewport
SPECIFICATION
C setdepth(near, far)
Screencoord near, far;
FORTRAN subroutine setdep(near, far)
integer*4 near, far
DESCRIPTION
viewport specifies a mapping from the left, right, bottom,
and top clipping planes in world coordinate values to screen
coordinate values. setdepth completes this mapping for
homogeneous world coordinates. The two arguments map the
near and far clipping planes to the desired screen
coordinate values. The default is setdepth(0, 1279). The
legal values range from 32767 (0x7FFF) to -32768 (0x8000).
When used for depthcueing or zbuffering, the range should be
restricted to (0x3FFF) to (0xC000).
The depth is the distance from your eye. setdepth is used
in zbuffering, depthcueing, and certain feedback
applications.
