A multiresolution framework for variational subdivision
Leif Kobbelt, Peter Schröder
Pages: 209-237
DOI: 10.1145/293145.293146
Subdivision is a powerful paradigm for the generaton of curves and surfaces. It is easy to implement, computationally efficient, and useful in a variety of applications because of its intimate connection with multiresolution analysis. An...

Jagged edges: when is filtering needed?
Avi C. Naiman
Pages: 238-258
DOI: 10.1145/293145.293147
Depiction of oblique edges by discrete pixels usually results in visible stair steps, often called jaggies. A variety of filtering approaches exists to minimize this visual artifact, but none has been applied selectively only to...

Boundary representation deformation in parametric solid modeling
Srinivas Raghothama, Vadim Shapiro
Pages: 259-286
DOI: 10.1145/293145.293148
One of the major unsolved problems in parametric solid modeling is a robust update (regeneration) of the solid's boundary representation, given a specified change in the solid's parameter values. The fundamental difficulty lies in determining...
