Documentation of "compositing shaders" X3D extension by Michalis Kamburelis, implemented in Castle Game Engine.

See http://castle-engine.sourceforge.net/compositing_shaders.php .

Includes a paper "Compositing shaders in X3D" for the TPCG conference 2011. And "Compositing Shaders in X3D" Ph.D. thesis.

Documentation of shadow maps extensions by Michalis Kamburelis, implemented in Castle Game Engine. This is a paper "Shadow maps and projective texturing in X3D" for the Web3D 2010 conference.

See http://castle-engine.sourceforge.net/x3d_extensions_shadow_maps.php .

Older documentation describing VRML and engine architecture. It's a little outdated now, it does not present a good engine overview now (instead, look at current engine documentation and tutorials linked on http://castle-engine.sourceforge.net/engine.php ). Still it documents a lot of useful information, like the description of how we use octree.

Unless otherwise notes, all the documentation is available on GNU GPL >= 2 license, just like our source code. There are some exceptions necessary --- conference papers must adhere to the conference copyright and licensing.
