DESCRIPTION
Gethitcode returns the global variable hitcode, which keeps a cumulative record of clipping plane hits. It does not change the hitcode value in any way.
The hitcode is a six-bit number, as shown below, with one bit for each clipping plane. (Systems configured without near-far clipping always return 0’s for the near and far clipping planes.)
