Seeking open source or free tool to open 3D Mesh GIS files?

Question

I'm looking a way to open 3d Terrain Mesh files.

I have four different folders with same 3d content , I'd like to open one of them :

1. Cesium folder (with internal Tile folder, web.config, tileset.json)
2. OBJ folder (obj, obj.mtl and with internal Tile folder)
3. OSGB folder (with internal Tile folder)
4. XPL3 folder (with folders floor, Tile and LODTreeExport.xml)

I'm looking for open source or free tool to open 3d Mesh listed above.

I tried to open each of them in meshLab and BlenderGIS both don't have options to open these files are listed above, same above google earth,Global Mapper, openSCAD, QGIS, AutoCAD Map3D, Sketch Up and GRASS.

I am new to the field of GIS.

You can try meshLab, it can open OBJ format files, and it is an open source software.

Also Blender can be another option which can import many format files and it is also open source and a very powerful 3D renderer. If you want to use GIS data with blender, you can use BlenderGIS with which you can import georeferenced raster data.
