NAME
PrimGenGBOXObject()
SYNOPSIS
geom_lib/primitiv.c:119
IPObjectStruct *PrimGenGBOXObject(VectorType Pt,
VectorType Dir1,
VectorType Dir2,
VectorType Dir3)
DESCRIPTION
Routine to create a GBOX geometric object defined by Pt - the minimum
3d point, and 3 direction Vectors Dir1, Dir2, Dir3.
If two of the direction vectors are parallel the GBOX degenerates to
a zero volume object. A NULL pointer is returned in that case.

Order of vertices is as 5 7
follows in the picture: | 6 |

PARAMETERS:
Pt: Low end corner of GBOX.
Dir1, Dir2, Dir3: Three independent directional vectors to define GBOX.
FUNCTION RETURN VALUE
IPObjectStruct *: A GBOX primitive.
