Visibility Sampling on GPU and Applications
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this paper, we show how recent GPUs can be used to very efficiently and conveniently sample the visibility between two surfaces, given a set of occluding triangles. We use bitwise arithmetics to evaluate, encode, and ...
Stylized Vector Art from 3D Models with Region Support
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
We describe a rendering system that converts a 3D meshed model into the stylized 2D filled-region vector-art commonly found in clip-art libraries. To properly define filled regions, we analyze and combine accurate but ...
Sample Based Visibility for Soft Shadows using Alias-free Shadow Maps
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
This paper introduces an accurate real-time soft shadow algorithm that uses sample based visibility. Initially, we present a GPU-based alias-free hard shadow map algorithm that typically requires only a single render pass ...
