Need information about the blender collada export code


I post here hoping to get information on where I can find Blender’s collada export code and how it works.

I am currently working on a project to allow Makehuman, an avatar creation software, to export avatars directly from Makehuman to Opensim/Second life.
Currently we need to import the collada file from makehuman into blender to export it again in collada with the right parameters. This is not effective and does not allow Makehuman to be used for normal users.

I therefore hope that you will support me by answering my questions.

Here is a link to the makehuman forum where the project is presented in detail : MakeHuman4SL/Opensimulator](


The Blender Collada integration code is here:
