Constructive Solid Geometry (CSG)
Description
The CSG branch demonstrates,
- Using the Union method to return a new Mesh consisting of Mesh A and Mesh B
- Using the Intersects method to return a new Mesh where Mesh A and Mesh B overlap each other.
- using the Subtract method to return a new Mesh where Mesh B is subtracted from Mesh A
To load the CSG example, checkout the csg branch.

Union
Return a new CSG solid consisting of A and B
A.union(B)
+-------+ +-------+
| | | |
| A | | |
| +--+----+ = | +----+
+----+--+ | +----+ |
| B | | |

Subtract
Return a new CSG solid where B is subtracted from A
A.subtract(B)
+-------+ +-------+
| | | |
| A | | |
| +--+----+ = | +--+
+----+--+ | +----+
| B |

Intersect
Return a new CSG solid where both A and B overlap
A.intersect(B)
