A Progressive Refinement Approach for the Visualisation of Implicit Surfaces
[chapter]
2007
Communications in Computer and Information Science
Preserved Fulltext
In this paper, we present an attempt at reducing the design cycle of an implicit surface modeler by introducing a progressive refinement rendering approach to the visualisation of implicit surfaces. ...
Visualising implicit surfaces with the ray casting method is a slow procedure. ...
CONCLUSIONS The rendering method, here presented, offers the possibility of visualising implicit surfaces with progressive refinement. ...
