I've been working on a 3d viewer for DS homebrew cards. Progress is a bit slow, but it is going nicely. This image shows one of Spaceys TF2 low-poly models. Textures still seem a little bit off, but overall it's looking quite nice.

There's two things I need to do before I release a first version:
- Online conversion to DS format (currently doing this offline)
- Simple file browser, so you can browse your entire card.

It currently only supports triangulated OBJ files, but I'm willing to implement any 3d format I can get specifications for. So far only static models are supported, but I do want to add animation after the initial release.


Downloads:
Version 10
- Use shoulder buttons to switch between file browser and logging
- Touch the screen to rotate the model
- OBJ support only

Version 11
- Hold LEFT and swipe the stylus up and down to zoom

Ok, this is damn cool.... *this* would be reason enough for me to get a DS!

hot damn. i have a DS and a Micro SD Super Card. this would rock my world.

Nice one [img]/images/graemlins/smile.gif[/img]
Might have to borrow Tully's DS and mess around with this when you release it!

I think .fbx would definitely be a format worth supporting, especially with the issues I've always had getting .obj's out of 3dsmax into other apps.

I've never had problems with OBJ out of Max... probably your settings. There are a lot to choose from, and just one or two set to different options can really change the way it's exported.

I agree that FBX would probably be a good format to consider though - it supports bones, animation, vertex weights and all geometry data you might need. Most apps should export it these days, I think.

Please complete this! it looks freaking awesome. For shits and giggles you could work on the md3 format, may help you play back some old q3 models with animations (if they are ds spec that is)

hey how do u make custom game disks? is it a normal sd card?

def keep an eye on this

You'll want an R4 cartridge and an SD micro card

yay this looks cool

what about camera options and mulitple materials, environment artist here, would be nice ====) to get a fps style walking cam option aswell=)

i fancy doing some more ds stuff

FAT Succes!

I SO CAN'T WAIT FOR THIS. Would be cool to have models span on both screens btw [img]/images/graemlins/smile.gif[/img]

You've had problems with Max exporting normals in OBJ, just like everyone else. Don't make me quote you.

Fantastic!

I'm in, where do I sign up?

sweet stuff! I found another 3dviewer before but didn't get it to work, hope you can make my dreams come true =)

I've done a quick search on this format, and it seems to be some kind of Autodesk proprietary format, although one that's relatively widespread. I wasn't able to find any specs, although there was an SDK on their site. It sounds fairly similar in idea to Collada, although I imagine the execution is very different.

When I add animations this will probably be my first step. Nice and easy keyframed vertex blending.

You can buy homebrew cards which look like real DS cards. They often take a microSD card onto which you can load whatever you want. So there's no need to hack your DS or anything like that.

Thanks for that Shepeiro. I loved your stuff when you pimped it! Multiple materials is already supported as I can load multi-part models. Currently no camera controls, but they are planned at a later stage.

Do you really think that would be useful? I was thinking of maybe adding a portrait mode, with the file browser on the touchscreen on the right/left, and the model at full height on the other screen. Would work well for characters I imagine, but possibly less so for other kinds of models, so it'd definately be an option. Spanning both screens is certainly possible, but I definately feel it'd be less useful, with the gap and all.


The file browser is up to a usable state at the moment, so pretty much all that's left for the first release is making the conversion happen online rather than offline. Since this involves using floats it may be bit more work than I'm expecting if I need to convert from floating point to fixed point earlier on in the process. I'm hoping to release this version before I'm off to GDC on Tuesday next week.

It could be a really cool thing. I am pressed to use it.

I've done a little bit of searching on FBX formats, and it looks like it's not going to be possible to get that onto the DS. Apparently support for using it in game-engines is 'sketchy': http://discussion.autodesk.com/threa...hreadID=492418

I like that idea. Sounds very useful.
I encourage the use of .obj files, and for animations, I suggest looking into perhaps .X or dotXSI.

ditto!

The DS fever is on! Great job!

Say when and where, I'm there!
