Current Status of the CSG based volumes
---------------------------------------
The CSG based volumes, i.e. UnionVol, DifferenceVol and IntersectionVol are currently an
experimental feature and may not always works as expected. While most basic operations do
work there are some things which are either not sufficiently tested or actually known not
to work. See below.
Known issues:
-------------
general:
- cascading CSG operations is not well tested and may lead to unexpected results
- using volumes with internal fitting surfaces, i.e. BoxWithJointSet or CylinderWithJointSet is untested,
the CSG operation may have unexpected effects on the joint set
DifferenceVol:
- if the difference would result in an empty volume, i.e the 1st volume is fully contained in the 2nd volume,
the calculation will not terminate
IntersectionVol:
- if the intersection is empty, i.e. the two volumes are disjoint, the calculation will not terminate
