Preprocessing occlusion for real-time selective refinement
Visibility computation and level of detail modeling are two important components of efficient scenerendering algorithms. Both aim to lessen the graphics load by lowering polygon c...

A microfacet-based BRDF generator
A method is presented that takes as an input a 2D microfacet orientation distribution and produces a 4D bidirectional reflectance distribution function (BRDF). This method differ...

GPU-based cone beam computed tomography
The use of cone beam computed tomography (CBCT) is growing in the clinical arena due to its ability to provide 3-D information during interventions, its high diagnostic quality (su...

Apparent layer operations for the manipulation of deformable objects
We introduce layer operations for single-view 3D deformable object manipulation, in which the user can control the depth order of layered 3D objects resting on a flat ground with...

Interactively Modeling with Photogrammetry
We describe an interactive system to reconstruct 3D geometry and extract textures from a set of photographs taken with arbitrary camera parameters. The basic idea is to let the use...
