Is there any open code to get information about COLLADA or OBJ files? I need a source code that takes as input a COLLADA file and/or an OBJ file, and gives as output basic information about the file, such as file size, model dimension, volume and if possible texture issues.
For OBJ Files

Free tools like MeshLab, Blender, and GLC_Player are able to load OBJ files and give you basic information about their content.

Apparently, GLC_Player can also load COLLADA.

In code you can use the following standard tools:


Assimp - Library for loading many common formats including OBJ
TinyObjLoader - .h/.cc only, no external dependencies
