popupid: csg](Mapping) The name given to the first stage of the map compile process. This stage often involves basic compilation operations such as initial surface subdivisions, texdata heap validation and initial hull construction. Often abbreviated as CSG. In ZHLT, this process is performed by the hlcsg.exe program.
Process of building new a 3D model from the from the subtraction, intersection, or union of two or more models in a scene.
one of the systems for modeling solid objects. Regular primitive shapes (blocks, pyramids, cones, etc.) are added to and subtracted from one another to create the desired object. Compare boundary representation.
(n) A method of 3-D solid modeling in which geometric primitives are related to each other in a binary tree structure via Boolean operations. Each primitive is defined as a solid by a group of analytic surfaces (half-spaces), and the final object is defined by the calculation of the Boolean operations between primitives.
Constructive solid geometry (CSG) is a technique used in solid modeling. CSG is often, but not always, a procedural modeling technique used in 3 D computer graphics and CAD. Constructive solid geometry allows a modeler to create a complex surface or object by using Boolean operators to combine objects.
