Abstract
To design objects or entire scenes in real time with free-form surfaces makes a shifting process to parallel architectures absolutely necessary. This migration has advantages in the computation phase but penalizes in the visualization phase. The present paper takes as an example a hidden-line sequential algorithm for parametric surfaces and proposes an optimized parallel version for a hypercube architecture provided with the capability to make graphic requests in parallel. Considerations of a general type result as well as the need to introduce a new metrics evaluation of the performances that keeps count of the graphic visualization phase. © 1995.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
