A Frame-dependent oracle for linear hierarchical radiosity: a step towards frame-to-frame
Martín Campos, Ignacio Clemente; Tost Pardell, Daniela; Pueyo Sánchez, Xavier (1996-01)
Report de recerca
Accés obertA frame-based oracle for Hierarchical Radiosity (HR) is proposed which takes into account the Gouraud shading interpolated intensity values mapped from the radiosities. The algorithm is based on a linear approximation ... -
A Global algorithm for linear radiosity
Sbert Cassasayas, Mateu; Pueyo Sánchez, Xavier (1993-11)
Report de recerca
Accés obertA linear algorithm for radiosity is presented, linear both in time and storage. The new algorithm is based on previous work by the authors and on the well known algorithms for progressive radiosity and Monte Carlo particle ... -
A parametric-space-based scan-line algorithm for rendering of bicubic surfaces
Pueyo Sánchez, Xavier; Brunet Crosa, Pere (1987)
Article
Accés obertA novel scan-line algorithm for displaying bicubic surfaces is presented. Patches are decomposed on regions of constant sign of the z component of the normal before the scan process. Most of the computations are done in ... -
Multilevel use of coherence for complex radiosity environments
Vilaplana Pastó, Josep; Pueyo Sánchez, Xavier (1993-02)
Report de recerca
Accés obertThe performance of radiosity algorithm has been improved in the last years by means of using coherence when evaluating the visibility function for form factor computation. We present here a characterization of the uses of ... -

Temporal coherence in progressive radiosity
Tost Pardell, Daniela; Pueyo Sánchez, Xavier (1993-02)
Report de recerca
Accés obertIn this paper we firstly present a study of the use of temporal coherence in radiosity algorithms. We underline the fact that this may be used even in static environments given that the behavior of a radiosity algorithm, ... -
The Use of visibility coherence for radiosity computation
Pueyo Sánchez, Xavier (1993-01)
Report de recerca
Accés obertCoherence has been widely used to improve the performance of visibility computation in traditional hidden line/surface algorithms. The appearance of radiosity algorithms has increased the importance of computing efficiently ...
