Abstract
To increase the mobile rendering capabilities
A new hardware architecture for rasterizing textured trianglesSaving memory bandwidthTo use as little power as possible
A scanline-based culling schemeavoids a significant amount of z-buffer reads
Interactive Shadow Generation in Complex Environments
Naga K. Govindaraju, Brandon Lloyd, Sung-Eui Yoon, Avneesh Sud, and Dinesh ManochaUniversity of North Carolina at Chapel Hill
Abstract
A new algorithm for Interactive generation of hard-edged, umbral shadows in complex environments with a moving light source
Mainly Based onLevels-of-detail (LODs) and visibility cullingA novel cross-visibility culling algorithmA combination of shadow polygons and sha

All-Frequency Shadows Using Non-linear Wavelet Lighting Approximation
Ren Ng Stanford University
Ravi Ramamoorthi Columbia University
Pat Hanrahan Stanford University
Abstract
Based on precomputed light transport, for real-time rendering of objects under all-frequency, time-varying illumination represented as a high-resolution environment map
Main contribution is to approximate the environment map in a wavelet basis, keeping only the largest terms
Compression by encoding the light transport matrix
Efficient Synthesis of Physically Valid Human Motion
Anthony C. Fang, Nancy S. PollardDepartment of Computer ScienceBrown University
Abstract
Traditionally, Differentiating physical quantities becomes prohibitively slow; obtaining first derivatives for these parameters is generally an O(D2) process. D = #DOF of the character
This paper describe a set of objective functions and constraints that lead to linear time analytical first derivatives
Rhythmic-Motion Synthesis Based on Motion-Beat Analysis
Tae-hoon Kim, Sang Il Park, and Sung Yong ShinKorea Advanced Institute of Science and Technology
Abstract
Synthesizing a new motion from unlabelled example motions while preserving their rhythmic pattern
Training DataCapture the motion beats from the example
motions to extract the basic movements and their transitions
Constructs a movement transition graph that represents the example motions
