Boolean Union
A boolean union of two primitives is analogous to 'merging' them together, and treating them as a single object. This graphic depicts a boolean union:
The red cube and the blue sphere are combined using the CSG union operator to create a single object, with the appearance of both primitives merged together.
Some software distinguishes the Union from a different operator, Merge, which does the union in such a way that the surfaces inside the merged region are not rendered. This would be desirable in cases where the objects are transparent, and the union should be treated as a single solid object. In particular, the POV-Ray graphics package implements this concept.
