I have seached this forum for performance numbers but with no luck. Can anyone please help me with: 1. Performance numbers; TL poly counts, Fillrate etc. 2. Any special hardware ligthning/shading capabilities If you have found other threads were this is being discussed, please drop me a link /MacDaddy
how many triangles is very different depending on what 3d engine you use(if you use one), the only one I know the specs of is sio2(http://www.sio2interactive.com/HOME/HOME.html). With the current version you can have 15k triangles drawn at 40fps+ on ipod touch 2G, in the next version it's 30k at 30fps+(still on ipod touch 2G), these numbers are with texture and maybe light, but without physics. How many triangles you can render per FOV depends on lots of things like: texture/multi texture physics light animation how much time everything except the drawing uses(AI etc.) For your second question: you can use OpenGL lights
You can find iPhone 3D benchmarks here: http://www.glbenchmark.com/phonedetails.jsp?benchmark=pro&D=Apple%20iPhone&testgroup=lowlevel It has triangle throughput, fill rate, etc. Also you can compare the iPhone to other mobile devices on that website.
Thanks a for the info guys! It's seem to be more powerfull than I initially had predicted - I was thinking DS times 1,5
Well theoretically its almost at the Dreamcast level, it based on the same PowerVR chipset that was used in the SEGA Dreamcast, though running on a lower resolution screen. But since its running with the iPhoneOS and that Apple made some restriction, we are probably loosing a bit performance. But the more people develop for it, the more they will find way to get their code optimized and I am sure Apple will do the same with the iPhoneOS also. Just take a look at the recent Need for Speed video from EA posted on the site here. It surely shows that it can be quite powerful. Fred
