I'm a newbie in COLLADA. I need would like to include landmarks in my 3D model, which would be 3D points (not necessarily vertices of the mesh) with a name, for example:
Code :"right index fingertip" 0.45 0.11 0.23
I haven't found any specific element in the file specification that fits this. What would be the recommended way of adding this kind of information to the file?
