## Castle Model Viewer Description
Viewer for 3D and 2D model formats supported by the Castle Game Engine: 

- glTF
- X3D
- VRML
- IFC
- Spine JSON
- sprite sheets (in Castle Game Engine, Cocos2D and Starling XML formats)
- MD3
- Wavefront OBJ
- 3DS
- STL
- Collada
- and more.

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.

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: 

This is an open-source software, available to you for free. There are no ads or tracking. We appreciate if you can support us:  !
