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

Throw it in a windtunnel :)

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

Carl Cates, yeah?
Just software?

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..

Yeah i saw the movies
Of the thing

The top simulates metal tearing

Beh the benchmarks so far have been awful

Benchmarks?

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

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

Cool
Realtime liquid simulation
Thats pretty damn awesome

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

Really awsome realtime liquid.
nice!!!

Imagine it'd be useful for simulating physics in a 3d animation scene
Instead of waiting ages

3D forums Enthusiast Joined: 30 Nov 2005 Posts: 53

Waiting ages?
maybe in max Wink

Nah
Reactor is pretty fast

Yeah it is
When you have the right world settings
Smile

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

Only in theory
PPU does very little right now

Depends on what you use it for

3D forums member Joined: 27 Jun 2006 Posts: 34

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.

You're talking about games
I said it could be used for 3d applications
