3d On Gp2x


There is no 3D hardware on GP2X, but XGP is planned to have 3D hardware. We could always port Yeti to GP2X though...
 
PS1 quality, probably very close to it in software, possibly even better. The Zodiac could come pretty close, but framerates weren't so great (i.e. Stuntcar Extreme & Spyhunter). But part of the problem for the Zodiac was the high resolution screen - the GP2X will be faster since it's half the Zodiac resolution. And if a good 3D engine is coded that really takes advantage of both CPU's, it could even do better.

N64 had some fancy effects like MIP-mapping, Bump mapping, anti-aliasing, anvironment mapping, trilinear filtering & perspective correction. So even though it couldn't pump as many triangles per second as the PS1, it could throw out smoother, more sophitsicated images. The GP2X won't be able to do all that fancy stuff.
 
Well, the ds haves a arm 9 at 67 mhz and a arm7 at 33 + some fancy chips (2d hardware/some very basic 3d stuff but iam not sure on that).
Gp2x haves 2*200mhz arm9 and a 2d accerlator.
It should be possible to get ds level stuff or higher at gp2x.
 
DS is a bit pointless thouugh as dual screen and touch screen can't be emulated..

The N64 also had z buffer which vould calculate polygon intersections accurately without polygon show-through. The good example of this was the wooden planks in the water that when tilted into the water had perfect waterline intersections.

It didn't do bumpmapping though. The Xbox was the first to support that in hardware. Games like Halo, Riddick, Doom III, the newest Splinter cell used that alot. This effect makes the texture behave like it is 3D.

Actually I just copied that list of N64 3D effects off some random site I got on google. :p It was innacurate, and I didn't really examine it.

But the main point is I doubt the GP2X could produce N64 quality 3D. But again, I could definitely be wrong. Thos 2 CPU's together could be capable of great things given enough time.

The real question is - will the GP2X hardware ever really get pushed hard for original 3D games? It's surely capable of some very good software based 3D engines.

I think he's just refering to the DS's level of 3D, not emulating it since it was a quality question and not directly an emulation question.

2d accelerator? I thought the second core was supposed to act as a 2d accelerator, but if it's true, it's only for the better :)

GP2X has accelerated 2D hw features such BitBlits, Area & Pattern fills, color expansion, image caching etc.. So there's a lot to exploit there.

The dreamcast could do bumpmapping (link).

Would games like Elite: First Encounters be possible?


Edit:
(as the source code isn´t released yet maybe I should add running under a dos emulator....)

I'd wager. I seem to recall it being rather old game, without a need for dedicated GPU. Heck, it ran on A500...


even if it would be hard to play on a handconsole, it would be a little cool to be able to walk around whith the galaxy in your hand... ;)

I see no problem why Elite wouldn't run really smooth on GP2X. I have Elite 2 somewhere, it ran very very fine on a 75MHz 486 with almost no RAM (can't remember, maybe 8). And although the game had a huge galaxy it came on 1 floppy. The 3 books it came with was a headache though. Never got very far, I usually got shot down by a prirate. Was also quite hard to controll. It would be impossible to run it emulated though as it needs a mouse or a propper keyboard. But it should be possible to make a port if anyone have the source.

Anyone played Escape Velocity? Originally a Mac game but EV Nova is ported to Windows. It's Asteroids meets Elite, would do amazing ported to GP2X I'm sure.
 
I think my brother had one or two copies of Escape Velocity sitting around the house, seemed interesting enough though I never played it myself.
