This is our collection of demo 3D models. Some are impressive 3D models, some (most) are simple models demonstrating some technical feature. Most of the models are in X3D and VRML formats, but in general various formats handled by view3dscene and Castle Game Engine are used. At the beginning of most files (remember that you can open X3D files in normal text editor too) you can find comments explaining what this file demonstrates.
These models were created to test our Castle Game Engine, but many of them should also be handled by other conforming X3D and VRML browsers.
warnings/ subdirectories are deliberately invalid
in some ways. Good X3D browser should display a sensible warning
message and (when possible) continue (omitting only the problematic part).
Comments and contributions to these demos are most welcome. See forum for ways to contact us. If you have a cool 3D model, something interesting, or maybe just something difficult for our engine, please share it with us! We love to see how you use our tools :)

You can always download the very current version of these models from SVN by:
svn checkout http://svn.code.sf.net/p/castle-engine/code/trunk/demo_models
Or you can get them from our GitHub project (auto-synchronized with SVN), like this:
git clone https://github.com/castle-engine/demo-models.git
Most of the 3D models here were created by Kambi (Michalis Kamburelis). Simple test models were simply manually crafted in a text editor. The more complicated meshes were created in Blender (see our Blender exporting documentation), you will find the .blend source files inside. For 2D art I usually use GIMP. Skies generated with Terragen.
Victor Amat provided a lot of interesting demos.
To mention some:
flat mirrors by
Screen Space Ambient Occlusion (see
shadow maps tests (including demo to visualize bias/scale,
test textures for spherical mapping testing (
Stephen H. France provided various tests for
Extrusion and others. Thanks!
Various models were based on OpenGameArt.org models, also some textures were taken from there. This is a great site where you can find models and textures on clear open-source licenses (GPL or CC), thousand thanks go to it's many contributors.

Also a lot of textures, see
Orin Palmer created plane model in 3DS, see
Many textures inside
are from public domain textures from unfinished game "Golgotha"
