Hi all, I would like to build a walking simulator and I will need a physics engine (to prevent collision with objects, etc.). I am thinking of using cesium because I need to use realistic geospatial data as well as the built-in 3d models of building and other objects. I also need fine grained contr…

Sure, here’s the CesiumJS learning center . Also, Sandcastle is a helpful resource for code examples.

Hi there, You are correct in assuming that CesiumJS does not integrate any physics engine. This is why our plugins for Cesium Unreal and Unity have been useful; The geospatial functionality of Cesium complements the offerings of game engines. CesiumJS should meet the requirements for loading geosp…

Thanks for your reply, Gabby. I have a followup question. I plan on creating custom 3D assest in Blender (such as buildings) that I will use instead of the out-of-the-box buildings that are found in CesiumJS. In this case, I would need to use three.js to render the blender assets. Is that correct? …

It’s possible to use custom 3D assets in CesiumJS. For a building, or other assets that don’t span a large geographical extent, you can load a glTF model asset. (This is also the recommended model format for Three.js, so the exported models would be compatible with either renderer.) I believe Blend…

I see. Thanks, Gabby. Could you point me to some documentation about 3d assets in CesiumJs (for my future referencce). Many thanks for your help

I am here after having built a physics based game in Unity but on the web export, the game will not compile due to C++ not compiling for WebGL or something. In any case, there seems to be no way to get physics interactions with Cesium on the web at all. Having found this discussion thread 2 years l…
