COLLADA Files Viewer [closed]

Question

UPDATE: looks like it's my own fault for not studying enough SketchUp's GUI. See my own answer.

Hi,

I'm planning to implement an "export to COLLADA" functionality in my mapping software, but I'm hampered by a lack of a good COLLADA files viewer. I've tried several applications:

1. Google SketchUp provides the best viewing experience I've come across so far, but importing COLLADA files is very slow. I tried this sample I found, but it takes 2-3 minutes to load it into SketchUp, and I'm running this on a decent machine. Since developing an export code involves a lot of trials and errors, SketchUp is just too slow for experimental work.
2. I've tried Blender, but the user interface is pretty alien for someone not doing day-to-day 3D games development. But I have to praise it for being able to load the sample file almost instantly, which makes me think SketchUp guys either do some deliberate slowing down of the import in the free version or they need to freshen up on their programming skills. (UPDATE: it turns out you can load it fast, see my answer, Sorry guys.)
3. I also tried some other free viewers, but they are either not showing the sample properly or they have very limited viewing capabilities (no panning or orbiting, for example).

I'd be grateful for any hints, but I'm looking for first-hand experience, not just googling (I've tried that myself). I realize this is not a typical programming question, but I see no better place on StackExchange to ask this.

Answer 1

There is also MeshLab which is free and open-source, cross-platform (Windows, Mac OS X, Linux), it supports several formats (COLLADA, VRML 2.0, 3DS etc.) and has extensive viewing capabilities (e.g. panning/orbiting).

Answer 2

COLLADA had now been replaced by glTF format.

F3D can open glTF and many other file format. F3D is a free, opensource VTK based software.

f3d file.gltf
