C SPECIFICATION    [Toc]    [Back]

     long gethitcode()

DESCRIPTION    [Toc]    [Back]

     gethitcode	returns	the global variable hitcode, which keeps a cumulative
     record of clipping	plane hits. It does not	change the hitcode value.

     The hitcode is a 6-bit number, with one bit for each clipping plane:

		  5	   4	    3	     2	      1	       0
	       _____________________________________________________
	       | far   |  near	|  top	 | bottom | right  |  left  |
	       |_______|________|________|________|________|________|

NOTES    [Toc]    [Back]

     This routine is available only in immediate mode.

     The symbolic values for the hitcode bits shown above are defined in
     <gl/get.h>.

     This routine only functions on IRIS-4D B and G models, and	therefore we
     advise against its	use in new development.
