Kambi VRML game engine

For developers: this is an open-source engine that is especially oriented towards working with VRML models (although other model formats are also supported). For more information, documentation and downloads for developers see lower on this page.

For normal human beings: this page is a collection of various games and tools. They were developed using the VRML game engine, but you don't really need to know what VRML is in order to use them. Two most important programs available here are "The Castle" game and view3dscene model viewer.

Latest update:

See the log of previous changes to these pages.

Games below are not extended anymore. They are mainly small toys and demos of the VRML game engine. I like them very much, and I keep them in working and compilable state, but that's it.

• glViewImage — image viewer, it can fully handle PNG, JPEG, PPM, BMP and RGBE formats
• bezier_curves — plotting rational Bezier curves
• glcaps — output some useful information about OpenGL libraries installed on your system.

So, you want to actually see how it all works inside, huh ?

Documentation and sources:

• Kambi VRML game engine — overview for developers
• Sources of Kambi VRML game engine and related programs
• VRML engine reference (generated by pasdoc)
• VRML engine documentation (more general overview of how the engine works).

More details about VRML format handling:

• Specification of my extensions to VRML
• Kanim (Kambi VRML engine animations) file format
• Kambi VRML test suite
• VRML implementation status
• Read my document describing how current VRML rendering optimization works, what are the possible drawbacks and what are the possible alternatives (and what drawbacks are hidden in those alternatives :).

And some more information, randomly related to the engine and the programs developed with it:

• Blender VRML stuff
• Standard command-line options understood by all OpenGL programs
• Notes related to programs using OpenAL
• Command-line options understood by all programs here
• Versioning scheme
• All Windows DLLs used by programs here (622 KB)
• Dependencies on Mac OS X
• kambi_mgf2inv — modified version of the mgf2inv program by Greg Ward, it outputs some additional info about physical material properties (concerning Phong BRDF)
• Programmers may be interested in:
  • Bump mapping techniques quick overview
  • Shading languages (in particular ARB vertex/fragment assembly programs, Cg and mostly GLSL) quick overview
  I wrote these documents when I was learning these techniques myself, they contain some summary and my findings, and links to other useful resources. You can take a look into our engine sources (in kambi_vrml_game_engine/.../examples/... directories, just look at the URLs of these documents) to see practical implementation of all these things.
