Way of representation schemes used in 3D objects

Question

Illustrate the way of representation schemes used in 3D objects?

Answer 1

1. Boundary representation (B-res) – It express the 3D objects as a set of surfaces which divide the object interior from environment.

2. Space- portioning representation – It express the interior properties with the help of partitioning spatial region including an object into a set of small, no overlapping, contiguous solids.
