2. About

This is Castle Game Engine collection of demo models. While some of them are more impressive, most of the models are simple and demonstrate some particular Castle Game Engine feature.

Most of the models are in X3D and VRML formats. but in general various formats handled by Castle Model Viewer 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.

Note: Files inside 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).

3. Development

Comments and contributions to these demos are most welcome. There are many ways to contact us.

You can clone the demo-models repository from GitHub. If you know your way around GIT and GitHub, you're most welcome to send contributions as pull requests.

4. Authors

Most of the 3D models here were created by 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.

Large/important contributions:

• Victor Amat provided a lot of interesting demos. To mention some: flat mirrors by RenderedTexture (see x3d/rendered_texture/), Screen Space Ambient Occlusion (see shadow_maps/ssao*), shadow maps tests (including demo to visualize bias/scale, shadow_maps/shadow_bias.x3dv), vrml_2/camera_{orient,rot}.wrl, orientation_interpolator_alum_box.wrl, test textures for spherical mapping testing (textures/spheremap-*.jpg). Thousand thanks!

• Stephen H. France provided various tests for TimeSensor, 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.

  Examples include Shinto Shrine (used for compositing shaders demo inside compositing_shaders/shinto_shrine/). Also a lot of textures, see compositing_shaders/textures/AUTHORS.txt.

• Orin Palmer created plane model in 3DS, see 3ds/p47d.3ds and 3ds/p47d.txt.

• Many textures inside textures/castle/ are from public domain textures from unfinished game "Golgotha"

• lion bump mapping textures from Philippe David steep parallax mapping code, based on paper about steep mapping.

• See also AUTHORS.txt files inside the archive for detailed and complete listing of authors and sources.

Thanks to everyone!
