do you know much about 3d on hand held formats?

hawken

looking to make a definitive guide for the polycount community.

Unfortunately the internet is a pack of lies. Lots of conflicting information abounds.

Can those of you working on titles help us out? PM me if you're not sure about posting potentially sensitive info.

thanks.

On PSP, we're pushing around 50,000 tris/sec I believe (depending on the camera). I'm not sure on our texture budget, but we certainly made things smaller. Most of our textures were reduced to 1/4 their original size. Screenshots here

We're not doing a DS version, so I'm unsure of it's specs.

I believe Jon Jones is working on hand-helds now, you could try and PM him or drop him an email if anyone has a good email address for him.

Jon Jones (PSP) and Telekineticfrog, Chris White, (DS)
I've learned tons of great information from both of these guys. Hit them up for info!

TelekineticFrog

You rang? Yep I work on Nintendo DS games and have since it was a big bulky green test board with LEDs blinking and a snes controller wired to it. If you want to know anything just ask and I'll help with what I can.

Are you sure that's not 50,000 tris per frame? 50,000 per second doesn't seem like much when you consider that according to Hawken's thread, the DS can do 2,000 polys per screen @ 60fps (which is 120,000 tris/sec per screen, which would be a total of 240,000 tris/sec).

err yea, per frame :P

I really don't think the DS can push 240,000 tris/sec though. Most PS2 games don't even push 240,000 tris per sec (textured, lit, transformed).

You're probably right. I just took the numbers and did the multiplication. They're probably performance figures based on pure triangle rendering without any sort of effects or textures or lighting.

tagHeuer would be a good source as well.

DS handles 2000 tris per frame just fine at 60fps. It does 4000 tris per frame at 30fps just fine as well. If you do 1 screen only with 3D you can wing the 4000 with no real issue. If you choose to do both screens 3D at same time you're looking at 2000 tris per screen both running at 30 fps. This works by rendering the screens 1 at a time so there is a slight but mostly unnoticeable delay in frame rate. It's never rendering both screens simultaneously. The game I'm currently working on utilizes 3D on both screens at the same time and plays well from what I've seen.
