Hi all! I'm new here, so start meeting with a question :-) I'm starting to develop a 3d engine with support od LUA scripting, but before I start whit the real work I tried to project how the things should be done. Now, my question is: which is the 3D file format that I have to use? I need somethig that isn't to hard to code, but must support animation and keyframes and , off course, that is free to use. Please, Help Me!?! Thanks a lot! [sorry for bad english ;-)]

Id be inclined to say 3DS as its a very robust well known format, with what your looking at, but can be a bit of a pain at times to work with (initially anyway).

If I were you Id look at Milkshape3Ds format .ms3d. It supports what your looking for including animation, should be able to find a sample code on google.

I'm looking at Milkshape3D format, but i hope olso in other advices about formats to implement.

Well it seems like you are looking for character formats so using that for a map just wouldn't work. Im not even sure if any models would work. You should look into the famous quake3 maps.

file format specs

You should be able to figure out how it works from there.

Hey man!

I'd recommend milkshape3d also... You can decompose many game formats ala half-life into .ms3d so you have some files to play around with. I just implmented a very good loader in dx9/animation if you need anyhelp lemme know.

I personally dont like milkshape because its matrices based :) but if using it you could use Milkshape's ascii format for start, where you can clearly see what is going on in the file.

My favorite, though not exactly a format, is Blender. All the api's are exposed and you can write your own export script however you want it. That's what I'm presently doing. The export script is written in Python, but it's easy to learn if you don't know it. Of course, writing an export script takes extra time, but you get exactly what you want. Blender is a nice modeler, too.
