Basic Examples  (1)

A tree of a CSG region:

Wolfram Language code: reg = CSGRegion["Union", {Ball[], Cuboid[], Ball[{2, 0, 0}]}];
Wolfram Language code: CSGRegionTree[reg]

Scope  (3)

CSGRegionTree works on intersection operations:

Wolfram Language code: reg = CSGRegion["Intersection", {Ball[], Cuboid[]}];
Wolfram Language code: CSGRegionTree[reg]

Union:

Wolfram Language code: reg = CSGRegion["Union", {Ball[], Cuboid[]}];
Wolfram Language code: CSGRegionTree[reg]

Difference:

Wolfram Language code: reg = CSGRegion["Difference", {Ball[], Cuboid[]}];
Wolfram Language code: CSGRegionTree[reg]

CSGRegionTree works on one-level CSG region:

Wolfram Language code: reg = CSGRegion["Intersection", {Ball[], Cuboid[]}];
Wolfram Language code: CSGRegionTree[reg]

Nested CSG region:

Wolfram Language code: reg = CSGRegion["Intersection", {Ball[], CSGRegion["Union", {Ball[], Cuboid[]}]}];
Wolfram Language code: CSGRegionTree[reg]

Intersection with more than two regions:

Wolfram Language code: reg = CSGRegion["Intersection", {Ball[], Ball[], Cuboid[], Ball[]}];
Wolfram Language code: CSGRegionTree[reg]

CSGRegionTree works on CSG regions in 2D:

Wolfram Language code: reg = CSGRegion["Intersection", {Disk[], Rectangle[]}];
Wolfram Language code: CSGRegionTree[reg]

3D:

Wolfram Language code: reg = CSGRegion["Intersection", {Ball[], Cuboid[]}];
Wolfram Language code: CSGRegionTree[reg]

D:

Wolfram Language code: reg = CSGRegion["Intersection", {Ball[{0, 0, 0, 0}], Ball[{1, 0, 1, 0}]}];
Wolfram Language code: CSGRegionTree[reg]

Properties & Relations  (2)

A CSGRegionTree is a tree:

Wolfram Language code: reg = CSGRegion["Union", {Ball[], Cuboid[], Ball[{1, 0, 0}]}];
Wolfram Language code: CSGRegionTree[reg]
Wolfram Language code: TreeQ[%]

Leaves of a CSG region tree represent primitives:

Wolfram Language code: reg = CSGRegion["Union", {Rotate[Ball[], 30Degree, {0, 0, 1}], Cuboid[], Ball[{1, 0, 0}]}];
Wolfram Language code: tree = CSGRegionTree[reg]
Wolfram Language code: TreeLeaves[tree]
