Opacity light fields: interactive rendering of surface light fields with view-dependent opacity
I3D '03: Proceedings of the 2003 symposium on Interactive 3D graphicsWe present new hardware-accelerated techniques for rendering surface light fields with opacity hulls that allow for interactive visualization of objects that have complex reflectance properties and elaborate geometrical details. The opacity hull is a ...
Binary Space Partitioning Visibility Tree for Polygonal Light Rendering
SA '19: SIGGRAPH Asia 2019 Technical BriefsIn this paper, we present a method to render shadows for physically-based materials under polygonal light sources. Direct illumination calculation from a polygonal light source involves the triple product integral of the lighting, the bidirectional ...
Relighting with 4D incident light fields
SIGGRAPH '03: ACM SIGGRAPH 2003 PapersWe present an image-based technique to relight real objects illuminated by a 4D incident light field, representing the illumination of an environment. By exploiting the richness in angular and spatial variation of the light field, objects can be relit ...
