But there is the tendency to save only what's needed in ascii and write down whole structs with binary. That's because modellers dump down whole state structures - binary game related formats may be smaller.

If you compress them into zip files that ratio is even larger 18KB to 11KB. I've got a rather small model 476 Faces, 296 Vertices, 25 Bones, the binary MisfitModel 3d file is 58KB and the ascii md5mesh is 44KB only. Some more considerations regarding size, bandwidth and loading performance: The goal would be to have light 3D files to spead up their loading, for instance for webgl games. What I'm looking for is for each vertex the list of bones (and weights) it is linked to.Īnother question : is there some people here who would find usefull to create a simple 3D file format ? (or reuse an existing one if it has the good specs).

I will update my post later and upload a python script to explain this.īut I definitely can't find where rigging information is stored : if someone has a hint or link, please post them (my few tries googling didn't gave me anything). I think I could find how to read animations. So far, I can load vertices and skeleton. The basic way to parse a blend file is given here : The file format is not easy to understand, so I'm starting a thread here to discuss about it.įor the moment, I'm interested in reading v 2.49 files such as Most 3D models here are stored in blender format, and the programmer who want to use them has to know how to read them.
