Massive Point Light Screen-Space Soft Shadows

Tuesday, September 14,2010
Just showed off a demo running on my laptop with the new point light soft shadow algorithm on the Korean Game Developer Conference. You can see screenshots of 16, 32 and 64 soft shadows on the Confetti website at http://www.facebook.com/pages/Confetti-Special-Effects-Inc/159613387880?v=wall On a desktop machine you can go higher than this but ...

Massive Point Light Soft Shadows

Wednesday, June 30,2010
Deferred lighting offers the ability to render thousands of lights. The next frontier in game development is to attach an equal number of shadows to those lights. This short note describes a new algorithm that can be used to render a large amount of shadows casted by point lights with ...

Cascaded Shadow Maps

Wednesday, May 05,2010
Some people were asking me about Cascaded Shadow Maps in the last few weeks. Here is a short high-level view how I see the development in the last five years in that area. More than five years ago I wrote the article "Cascaded Shadow Maps" in ShaderX5. At the time I ...

Cached Shadow Maps

Tuesday, December 09,2008
A friend just asked me about how to design a shadow map system for many lights with shadows. A quite good explanation was given in the following post already in 2003:
http://www.gamedev.net/community/forums/viewreply.asp?ID=741199
Yann Lombard explains on how to pick a light source first that should cast a shadow. ...

Dual-Paraboloid Shadow Maps

Sunday, December 07,2008
Here is an interesting post on Dual-Paraboloid Shadow maps. Pat Wilson describes a single pass approach here http://www.gamedev.net/community/forums/topic.asp?topic_id=517022 This is pretty cool. Culling stuff into the two hemispheres is obsolete here. Other than this the usual comparison between cube maps and dual-paraboloid maps applies: the number of drawcalls is the ...

Stable Cascaded Shadow Maps

Friday, June 13,2008
I really like Michal Valient's article "Stable Cascaded Shadow Maps". It is a very practical approach to make Cascaded Shadow Maps more stable. What I also like about it is the ShaderX idea. I wrote an article in ShaderX5 describing a first implementation (.... btw. I re-wrote that three times since ...
