Iso-charts: Stretch-driven Mesh Parameterization using Spectral Analysis (2008)
R. Scopigno, D. Zorin, Kun Zhou, John Snyder, Baining Guo
We describe a fully automatic method, called iso-charts, to create texture atlases on arbitrary meshes. It is the first to consider stretch not only when parameterizing charts, but also when forming...

Abstract We approximate a solid object represented as a triangle mesh by a bounding set of spheres having minimal summed volume outside the object. We show how outside volume for a single sphere can...
Abstract Parameterized Animation Compression (2008)
Ziyad Hakura, Jed Lengyel, John Snyder
Synthetic images can be parameterized by more than time or viewpoint. We generalize image-based rendering by exploiting texture-mapping graphics hardware to decompress ray-traced animations. The...
Image-Based Proxy Accumulation for Real-Time Soft Global Illumination (2008)
Peter-pike Sloan, Naga K. Govindaraju, Derek Nowrouzezahrai, John Snyder

Signal-specialized Parametrization, Pedro V. S, Steven J. Gortler, John Snyder
To reduce memory requirements for texture mapping a model, we build a surface parametrization specialized to its signal (such as color or normal). Intuitively, we want to allocate more texture...
Resolving Non-Binary Cyclic Occlusions with Image Compositing (2007)
John Snyder, Jim Blinn, Jed Lengyel
Given an occlusion graph for a group of objects that contains no binary cycles, and a set of antialiased images with transparency for each of the (isolated) objects, image compositing operators can...

Rui Wang, Kun Zhou, John Snyder, Xinguo Liu, Hujun Bao, Qunsheng Peng, ...
Object approximation using sets of simple primitives plays an important role in many time-critical applications in computer graphics, such as collision, hit, and proximity detection, view-frustum and...
Realtime soft shadows in dynamic scenes using spherical harmonic exponentiation (2006)
Zhong Ren, Rui Wang, John Snyder, Kun Zhou, Xinguo Liu, Bo Sun, ...
Previous methods for soft shadows numerically integrate over many light directions at each receiver point, testing blocker visibility in each direction. We introduce a method for real-time soft...

Clustered principal components for precomputed radiance transfer (2003)
Peter-pike Sloan, Jesse Hall, John Hart, John Snyder
We compress storage and accelerate performance of precomputed radiance transfer (PRT), which captures the way an object shadows, scatters, and reflects light. PRT records over many surface points a...
Bi-Scale Radiance Transfer (2003)
Peter-pike Sloan, Xinguo Liu, Heung-yeung Shum, John Snyder
Radiance transfer represents how generic source lighting is shadowed and scattered by an object to produce view-dependent appearance. We generalize by rendering transfer at two scales. A macro-scale...
