I can do basic 3d but md2 viewers are beyond me. I know some people did viewers for the GBA using asm, (which I don't like). Is anyone working on an opengl style md2 viewer? With the possibility of open source? I think a nice easy to understand viewer would open the door to a lot of quite good 3d games being made...

It's not all that clever, but I'm in the middle of doing one.
Should be done this weekend, unless the horrible work crunch continues. I'm doing a converter rather than a pure viewer. Most of the source code already exists if you search for 'opengl md2 source' or the like.

Are you converting md2 file into another type or reading them directly similarly to a bin file?

of course you would need to convert them, this is just because of the way MD2 files are stored. It is a lot easier (and probably faster) to convert them into an easy-to-use format first.

Any suggestions?

Maybe wait until ecurtz has finished it?
I wrote several MD2/MD3/BSP renderers for PC in the past, but i don't have a DS and i am not into DS dev but i think a quake 3 map renderer would be nice too (there are loads of tutorials about quake 3 maps on the net)

I'm converting to the encoded vertex format that Metroid uses, on the assumption Nintendo knows what they're doing.
It's just pasted together from other people's existing code, including an openGL viewer and the Metroid model viewer code that someone here wrote (mike260 maybe?, sorry I didn't find the original post in my super quick search...)

You can throw this data directly at GX_FIFO and the hardware will route it to the right registers. The following should be in ndslib soon:

Haven't tried it with the metroid models yet but it works ok for display-lists I built myself.
