How do I test the aerodynamics of my new concept car?

No need for a windtunnel tho.. you could use a physx engine

It's also a hardware
PPU = physics processing unit
XSI 5 advanced supports Ageia PhysX actually

Oh that thing
Aegea
Or something
About 20k physics objects at one time eh?

Ageia bought Meqon too
So they ought to be the best on the subject
40k boxes colliding simultaneously instead of 40 boxes
And alleviates CPU
Plus it simulates liquids , etc

Check both videos..

Like with the same amount of stuff but on their card - the game runs slower

Hehe nice
I was thinking it would be difficult with benchmarks when there are no competitors

Cool
Realtime liquid simulation
Thats pretty damn awesome

Of course not... if it runs slower than on the cpu - you have a problem

Really awsome realtime liquid.

But if you want a REALLY complex scene.. using the CPU will be slow anyway
Not talking about software limitations here.. just the vast hardware difference of PPU vs CPU
For that kind of calculation

Show me one benchmark it does any good on
Heh
Besides their own Cell Factor
Nothing uses it efficiently right now
If at all even
ATI is aggressivly seeking their own GPU based solution.

I've only heard XSI announce it
But I don't believe it's implemented yet
If it has, there has been no testing of it yet

Right now it needs the game more so
Game market*
So they need a few killer titles
Or it won't go past infacy
Especially if ATI or nVidia can counter it

I doubt it will die off
This isn't some premature gimmick like Virtual Reality in 95
It will either live on in some form or another
Either as part of Nvidia/ATI Gpu's.. or as a function in SLI-solutions
Or Ageia will conquer that market

I'm not talking about physics acceleration in general
I'm speaking of Ageia
And their sucess
They need to justify now a reason to own a $200 physics card

Gobbled up by Nvidia
Nvidia was one of the "babies" born out of the GPU generation
You are talking not just about Ageia specifically, but the concept and idea of a tertiary PPU
Whether it be in the form of Ageia... or Ageia bought up by Nvidia
Or ATI
did you see that documentary?

To be exact 1 hour 13 minutes
They wouldn't have the same know-how that Meqon/Ageia has though..
The problem is that the PPU requires cooling
Both chips under one fan?
I would hope one of them just bought Ageia and assimilated it into a GPU :p
If they'd try it alone, without their experience, I know they'd just do it halfassed

Or they could try to amass industrial experience from scratch (or do industrial espionage on ageia)

Nothing beats Meqon
Those are just halfassed crossfire/sli solutions
Am I right?
Or is it a GPU doing both graphics and physics?
Because I've read that is gonna be more possible with Dx10

Ati and nvidia will have the ability to run both physics and graphics on 1 gpu , or dedicate 1 gpu for physics specificly if in SLI

Hey, I think I'll try to be help and actually answer the question you asked. So you are going to need a physics engine, and assuming your an artist, it will have to be an engine that already exists inside an application. The only applications that I know of that will do what you want are game engines. Many engines have free/non-comercial versions, so I'm sure you could find one.
***NOTE***
Simulating aerodynamics is not standard in most physics engines, so before you down-load see if it supports what you need.
Other than coding a program yourself, I really can't see any other solution, but I hope you find it. And everyone else can continue a conversation that makes no sense to you
