CSG of a cone and a cube. Shows Union (row 1), Intersection (row 2), cube subtract cone (row 3), cone subtract cube (row 4).
The binary set operations Union, Intersection and Difference can be performed on any two non-mesh primitives as well as on the result of a CSG operation (giving CSG trees).
CSG of a cone and a cube. Shows Union (row 1), Intersection (row 2), cube subtract cone (row 3), cone subtract cube (row 4).
Nested CSG. Column 1 is A = ((sphere - torus) U cylinder), column 2 is (A U cube) and column 3 is (A intersect cube).
Simple CSGs showing colour combinations
Complex CSG. The main box is a cube removed from another cube. Each "peg" is a cylinder removed from another cylinder. The full block is the union of the main box with 3 of the pegs. The word LEGO is constructed out of cylinders, spheres and tori and is then subtracted from the front face of the block.
