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:
News - white_dune, X3D, movie textures, engine icon (July 15, 2008) :
Various exciting news about development of our engine:
White dune,
free software VRML 97 modeller,
can export normal VRML animations
(expressed in terms of VRML interpolators) to our Kanim (Kambi animations) file format and it supports our extension nodes and fields (run with -kambi command-line option, or use "Start next time
with kambi support" menu item). Thousand thanks for
Joerg "MUFTI" Scheurich!
Among the many new features already implemented in SVN are:
Reading X3D files, with all 40 X3D components,
in both XML and classic VRML encodings,
is implemented.
Besides all features from VRML 2.0, many X3D-specific
features are already supported, like
geometric primitives [Indexed][Triangle/Quad][Fan/Strip]Set (8 nodes total).
Rendering internals were reorganized into much smarter hierarchy, to handle
these new X3D nodes as well as IndexedFaceSet and other VRML 97 and 1.0
nodes implemented since a long time.
Extrusion node handling.
New extensions, like BlendMode node (a subset of
Avalon BlendMode node)
and KambiInline (an Inline that can somewhat
process the inlined content).
Texture department:
Textures with full alpha channel are now nicely rendered with blending
(and textures will simple alpha channel are still detected and rendered
faster by alpha_test). Moreover, MovieTexture node is now
handled (movie can be read from image sequences, like image%d.png,
and from normal movie formats thanks to ffmpeg).
As a demo, see the flames animation on the right.
(You can also download
AVI version with perfect quality.)
Flames movie above was not only played in our view3dscene, it was also
recorded directly by view3dscene. That's right: Screenshot options
were much improved, it's now possible to capture animation
as a movie file (with perfect quality, as opposed to using independent
programs that capture OpenGL output).
GNOME users will be happy to
hear that view3dscene can be easily used as nautilus thumbnailer,
so you can see thumbnails of your VRML / X3D and other 3D model files
(see the screenshot).
We have an icon for our engine and view3dscene.
Next view3dscene release will be nicely integrated with GNOME
(and other desktops that support relevant freedesktop specs).
You can already appreciate engine icon at the top corner of our main page.
Thanks to Kasia Obrycka for icon improvements!

Programs: Main games, VRML tools
"The Castle" First-person perspective game, in a dark fantasy setting. |
view3dscene Viewer for VRML 1.0, VRML 2.0 (aka VRML 97),
3DS, MD3, Wavefront OBJ and Collada models. Move in the virtual scene,
with collision-checking and gravity,
use embedded ray-tracer, convert 3DS, MD3 etc. files to VRML 1.0. |
rayhunter Command-line simple ray-tracer (classic deterministic ray-tracer and
basic Monte Carlo path tracer implemented).
See also it's gallery. |
Programs: Older games
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.
lets_take_a_walk Small 3d game-like toy, demonstrating OpenGL integrated with OpenALs
spatial sound. |
malfunction 3D space-shooter. This was the first game made by me that used VRML models. |
kambi_lines Arrange colored balls in lines. Quickly. |
Programs: Computer graphics, others
glplotter Plotting graphs (e.g. of functions). |
- 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.

If you will use any part of this engine, then make me happy and
drop me a note about this !
