Detailed Description

Intersect a ray with a displacement map.

The bounding box planes (in dsp coordinates) are numbered 0 .. 5

For purposes of the "struct hit" surface number, the "non-elevation" surfaces are numbered 0 .. 7 where:

Plane # Name plane dist -------------------------------------------------- 0 XMIN (dist = 0) 1 XMAX (dist = xsiz) 2 YMIN (dist = 0) 3 YMAX (dist = ysiz) 4 ZMIN (dist = 0) 5 ZMAX (dsp_max)

6 ZMID (dsp_min) 7 ZTOP (computed)

if the "struct hit" surfno surface is ZMAX, then hit_vpriv[X,Y] holds the cell that was hit. hit_vpriv[Z] is 0 if this was an in-hit. 1 if an out-hit
