Castle Game Engine internals
(Outdated) Overview of the Castle Game Engine and VRML 1.0

Most of this documentation was originally written as my master's thesis, passed in September 2006. Although I was occasionally updating and adding content to this document later.

Warning: This document isn't a good introduction to the Castle Game Engine (anymore)!

• It talks too much about engine internals.
• It shows too little of the engine API (and features) used during normal game creation by a developer. It doesn't even mention many of the key engine features added in engine >= 3.
• It discusses many features of VRML 1.0, which is a very ancient 3D format nowadays. The document doesn't show (in depth) features of VRML 2.0, modern X3D, and many enhancements of X3D in Castle Game Engine. Or glTF.

• HTML (split in many pages)

Sources archive (full DocBook sources, Makefile, XSL, images — everything you need to remake the HTML / PDF outputs above) :
vrml_engine_doc.tar.gz (11.5 MB)

You will need docbook (search for docbook, docbook-xsl, xmlto packages) to make HTML version of the document from DocBook sources. Additionally you will need fop (version >= 0.9x) and ttf-dejavu font if you want to make PDF version.

You can also get the latest version from the GitHub repository (in vrml_engine_internals).

The example VRML 1.0/2.0 models, used for screenshots in this work, are available inside our VRML/X3D demo models (see in vrml_engine_doc_simple_examples subdirectory). So you can view them comfortably in view3dscene etc.
