Anyone do any 3D for mobile?

Has anyone done anywork for a mobile 3D realtime game--n-Gage or any other phone w/ 3D support? I'm wondering what polycount and texture sizes you had to work with--characters/props, anything. Thanks!

    The NGage seems to take PS1 games, should have roughly similar constraints, same for the DS and PSP.

    I have made a vehicle for a 3d cell phone game for a competition on gamedev.net. The vehicle had 67 polys and used a 64x64 texture. Besides that I had made some textures and graphics. All are in here: http://www.xs4all.nl/~tetsuo/images/DF_assets.jpg

    I was contacted a week or 2 ago for free-lance gig to make characters for a cell phone FPS game. The limits were 350 polys, about 250 verts and a 128x128 texture for the highest LOD model.

    I think that the current cell phones that can handle games for serie 60 or Symbian (like the NGage)the 3d specs are roughly the same as a DS. Check out the DOOM DS project site for examples of their work.

    Ngage isn't anywhere near as powerful as the DS.

    Its been a while since I worked on Payload for the Ngage, a futuristic free roaming car game, but if I remember correctly, we were looking at around 50 polygons for the vehicle models (cut down in favour of more funky special effects), up to about 120 for buildings and perhaps a couple of hundred for the height mapped terrain. 64*64 should be the maximum size for textures given that NGage doesn't do blending and will just turn anything higher res into a pixelated mess.

    Its also worth noting that the NGage has a similar problem to the Playstaion/PS2/PSP in that its not very good at understanding large flat planes (I forget exactly what the technical reason is), resulting in some nasty texture warping unless theres a few tesselations to give it a some verts to work from.

    For comparison sake, our current DS title, the indoor rooms weigh in at around 1200 polygons with up to four 3-400 polygon characters on screen at a time, which doesn't cause any noticable frame drop. The Ngage would probably melt if tried that on it.

    Performance charts are more along those lines.

    Isn't the DS supposed to be a bit more capable than the N64?

    As far as i know, the DS is pretty much just a GBA with a 3d layer. It still has pretty much all the same GBA restrictions for the palettes and colours.

    The PSP is an insanely powerful little beast - you might as well consider it to be a PS2 because although it isn't as powerful, the smaller screen size means less to render, making it comparable. Its a PS 1.9.

    I just saw some stuff running on it that will blow your wee socks off.

    The DS isn't bad for 3d. 2048 Polys on screen at a time is the maximum I believe, although that goes against my estimated polycounts in my previous post so somethings not quite right there.
    Not really sure how that compares to the likes of PS1/N64/Dreamcaste

    DC is pretty close to the Ps2 really, just a few bits and bobs are better on the ps2, remember these two consoles were released around the same time!!

    DS must use a much better palette that the GBA

    dreamcast was better than the ps2. just didn't get the developers support from some of the big names. plus how easy it was to pirate games. then there's the stigma from the saturn which didn't help. many factors doomed the dreamcast frown.gif

    Hawken do you have something against Amiga?
    my custom 060/50MHz A1200 AGA 2MB is capable of playing Quake and Quake 2 at 320x200, it's a very capable machine.

    Playstation 2 really shouldn't be in this topic, it also quite frankly has such a different pipeline to everything else you can't say it's better or worse.

    As far as the hand-helds go. Well the N-Gage is quite powerful, 100MHz StrongARM 9 CPU iirc; which handled Tomb Raider direct translation quite beautifully at [email="180x240@12fps."]180x240@12fps.[/email] At times it could have as many as 2,500poly on-screen with alpha and particle effects. It is very restrictive count to think about in today terms but the unoptimised Playstation 1 engine could only push that at 15fps, later engines were capable of doubling this.

    NDS can seriously push the polygons though, in terms of power it's about on-par with the N64 4MB. Though as far as the Playstation Portable goes, it's about double the power of the PS1. Though with it's dual graphics pipeline (inherited from the PS2) it's capable of doing some cool effects. It can enhance the graphics, but doesn't stop the fact that your polycounts still have to be quite low.

    Most of the counts will depend on the engine though.
    I mean think about it, without or sparely using textures you can use almost double the polycount at the same speed. Several more polygons in the memory so much larger worlds too.

    I'd suggest doing some research on the given system you want to develop for, see what engines and devkits are like. Work up from there.

    With the Imageon and GoForce now in cellphones, graphics are seriously jumping for mobiles. I'm actually surprised neither the PSP or DS are using either.

    GoForce3D 4x00 Series is SERIOUSLY impressive. Almost as powerful as a GF3 for the cellphone. Crazy really.

    Thanks for all the responses! And thanks for posting those assets, too, Ikraan.

    Anyone worked on a 3D capable phone, like the LG VX8000, and know how it would compare to something line nGage? Oh, and if there's a mobile-centric-polycount-ish site? Thanks again!

    I'm not. Their battery lives are bad enough as-is.
