Computing Depth Contours with Graphics Hardware

Triangle-Based View Interpolation without Depth-Buffering

In this paper, we propose a triangle-based view interpolation algorithm which can correctly resolve the visibility problem without depth-buffering. The algorithm is especially useful when depth information is not available, such as in the case of real-world photographs. By subdividing the reference image into variable-sized triangles, view interpolation can be done efficiently using existing gr...

VLSI Drawing Processor Utilizing Multiple Parallel Scan-Line Processors

In a typical graphics system, a single drawing processor is used to perform pixel level drawing operations, one pixel at a time. A VLSI based drawing proces­ sor and image memory controller is presented which takes advantage of scan-line partitioning of many graphics operations. A four processor implementation is described which operates on four scan-lines in parallel to achieve near real-time ...

Efficient Cloth Model and Collisions Detection for Dressing Virtual People

This paper describes a fast technique for dressing virtual humans with different pieces of clothing. It exploits a mass-spring cloth model but applies a new velocity modification approach to overcome its super-elasticity. The algorithm for cloth-body collision detection and response is based on image-space interference tests, unlike most of the existing ones, which use objectspace checks. The m...

The Video Mesh: A Data Structure for Image-based Three- dimensional Video Editing Citation

This paper introduces the video mesh, a data structure for representing video as 2.5D “paper cutouts.” The video mesh allows interactive editing of moving objects and modeling of depth, which enables 3D effects and post-exposure camera control. The video mesh sparsely encodes optical flow as well as depth, and handles occlusion using local layering and alpha mattes. Motion is described by a spa...
