Castle Model Viewer

Mobile-friendly viewer for 3D and 2D models like glTF, X3D, VRML, Collada, Wavefront OBJ, Spine JSON and many other formats supported by the Castle Game Engine.

In addition to the above formats, it also allows to open a ZIP file that contains a single model and associated media (like textures, sounds etc.).

You can change navigation type (walk, fly, examine, 2D), jump between viewpoints, play chosen animations, save a screenshot, display scene statistics (triangle, vertex count) and more.

Usage

The application comes with a few sample files, and naturally you can open your own 3D and 2D model files.

The models must be self-contained, e.g. you have to

• use GLB with all the textures packed in one file,
• or X3D with all textures expressed as PixelTexture or data URI,
• or just put your model with data (like textures) inside a zip.
• We have documented how to make your models self-contained here.

Building

Compile by:

• CGE editor. Just use menu items "Compile" or "Compile And Run".

• Or use CGE command-line build tool. Run castle-engine compile in this directory.

  To upload to Google Play as AAB, place here correct AndroidSigningProperties.txt and then run:

  castle-engine package --target=android --package-format=android-app-bundle --fast
  

  (Remove --fast if you don't trust FPC to make a correct incremental build.)

• Or use Lazarus. Open in Lazarus castle_model_viewer_mobile.lpi file and compile / run from Lazarus. Make sure to first register CGE Lazarus packages.
