 Parallel-Split Shadow Maps on Programmable GPUs 

Fan Zhang, Hanqiu Sun, Oskari Nyman
To appear in the NVidia's upcoming book GPU Gems 3, published by Addison Wesley.

Project Page  (implementation details and source codes)

Highlights: In this paper, we further extend our PSSMs algorithm to the next generation of
gaming platform (Vista + DirectX10). Three clean self-included implementations (in both
DirectX and OpenGL) are provided:
1) PSSMs without hardware-acceleration,
2) PSSMs with DX9-Level hardware-acceleration and
3) PSSMs with DX10-Level hardware-acceleration (definitely new for developers! :).

Parallel-Split Shadow Maps for Large-scale Virtual Environments

Fan Zhang, Hanqiu Sun, Leilei Xu and Lee Kit Lun,
in Proceedings of ACM/SIGGRAPH VRCIA 2006, Hong Kong, China.
14-17 June, 2006. Published by ACM SIGGRAPH.

Paper: ~9M, BibTex   Project Page (implementation details and source codes)
Generalized Linear Perspective Shadow Map Reparameterization 

Fan Zhang, Leilei Xu, Chenjun Tao, Hanqiu Sun,
in Proceedings of ACM/SIGGRAPH VRCIA 2006, Hong Kong, China.
14-17 June, 2006. Published by ACM SIGGRAPH.

Paper: ~1.4M, BibTex
 

Notes: In the VRCIA print, the singularity "\theta=fov/2" in Equation (5), (7) and (8)
should be replaced with "\theta=\gamma" to guarantee the near-plane value is positive
(not only non-negative). Because all pixels will be mapped into single shadow map texel
when the near-plane value is zero, such that the warping is meaningless in practice. Where
\gamma > fov/2 and can be manually specified by users. This slight modification has no
any impact on the basic idea, and it is only for the strictness of our theory. The version
from the above link has been revised already.


High Quality Shadow Rendering with Parallel-Split Shadow Maps

Fan Zhang, Hanqiu Sun, Leilei Xu and Lee Kit Lun,
in Proceedings of the 7th ACM Postgraduate Research Day 2006
(ACM-HK Annually Local Activity), Hong Kong, China.
March 25, 2006. Published by ACM Hong Kong Chapter.

Paper: ~8.4M
Technical Report (TR05-07-12): ~12M (More details provided)

Notes: The major differences between this version and our VRCIA paper are that,
1) the mip-map structured textures used in this version, and
2) a simplified theoretical analysis for smooth transition of shadow qualities is
presented as well.
