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
