What are the various representation schemes used in three dimensional objects?
Boundary representation (B-res) - explain the 3 dimensional objects as a set of surfaces that separate the object interior from the environment. Space-portioning representation - explain interior properties, by partitioning the spatial region having an object into a set of small, no overlapping, contiguous solids.
