Both my math and my Google-fu is failing me at the moment. I'm trying to calculate the volume of a shape (see attached file) given the following conditions:
The shape is defined by six points:
PF PG PH
PA PB PC
... where:
PFxy = PAxy
PGxy = PBxy
PHxy = PCxy
PFz != PGz != PHz
PAz < PFz
PBz < PGz
PCz < PHz
Now if the distance between vertically coresponding points was the same for each point, it would be simple area x length, but thats not necessarily the case here. I can't use (vla-get-Volume...) as the shape doesn't actually exist except for lists of points.
Any suggestions?
