Using Subdivision on Hierarchical Data to Reconstruct Radiosity Distribution
(Blackwell Publishers Ltd and the Eurographics Association, 1997)
Computing global illumination by finite element techniques usually generates a piecewise constant approximation of the radiosity distribution on surfaces. Directly displaying such scenes generates artefacts due to ...
Interpolatory Subdivision on Open Quadrilateral Nets with Arbitrary Topology
(Blackwell Science Ltd and the Eurographics Association, 1996)
A simple interpolatory subdivision scheme for quadrilateral nets with arbitrary topology is presented which generates C1 surfaces in the limit. The scheme satisfies important requirements for practical applications in ...
