So, I'm well aware you can export a .blend file to a .obj and read that with pretty standard file i/o in c++.
What I want to know is how to un-obfuscate a .blend file AND
read in the information in the file as text or python code if possible OR just know how a .blend file is structured or how blender stores data and compiles the .blend, and in what order like the data types and data structures stored
because I want to access the information for the materials used, the animations key frames, the composition of the scene, etc.
EDIT: well so far I've found these useful sources
haven't found everything i'm looking but this was a lot of help so far.
edit: there may have been important information one here, but now it's gone anyone know where the blender team moved it to?
edit: i gave up trying to parse the file just did an exporter in blender's python script, i got it to export the mesh data so far in an obj like format, now working on extracting the animation data. i'm using the api ref in mike's answer.
