"Consistent Solid and Boundary Representations from Arbitrary Polygonal Data"
Symp. on Interactive 3D Graphics, 1997, p. 155-162.
- How is the "solidity" of each spatial cell defined ?
- How is it determined from the input data ?
M. Higashi et. al
"Robust algorithms for face-based representations"
CAD, Vol 29. No 2, 135-146, 1997.
- What are the justifications and advantages of using the faces as the primary element in the new data structure ?
- What is the core geometrical operation on which the calculation of Boolean set operations is based ?
