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: https://castle-engine.io/castle-model-viewer-mobile This is an open-source software, available to you for free. There are no ads or tracking. We appreciate if you can support us: https://www.patreon.com/castleengine !
