Hi there,

little aura test.

wow!!!! that's really great!!!

Samuel,

I'm assuming you are one the handful of people beta testing before it goes into open beta. I am not in this handful so I was wondering if you would be willing to run a really simple scene for me. I just want to see what it looks like as well as see how aura reacts in this certain situation. If you are interested email me or post back here. Thanks!

Hi there,

well, I´m willing but i can´t give you informations on features an capabilities. You could ask Evtim from Chaos, maybe he can give you
some further infos. sorry

Samuel,

I talked to Evtim at Siggraph and watched him demo Aura. I was just curious as to how Aura would react in this certaiin situation. I seen him use a particle system to guide fire....so i want to see what happens when particles are animated and stick to the ground.

I was going to send a MAX file but heres a script that will create the scene that i'm talking about.

Copy this into a empty script window and evaluate it.

set animate on
sliderTime = 100f
move $ [208.284,0,0]
set animate off
sliderTime = 0f

basically i want to see if the particles that are stuck on the ground still burn or stay on fire.

Thanks...looking forward to the public beta!!!!

Hmmm...it didn't copy the line breaks. Okay the scene is this:

-make a long deflector with 0 bounce and 100 friction
-then make a superspray just above the deflector pointing down at it on an angle
-animate the superspray from one end of the deflector to the other
-spacewarp link the superspray to the deflector.
-the particle system should travel across the deflector emitting particles that stick to the ground.

Let me kow if i'm not being clear enough and i'll email ya a file.

Thanks.

Chris,

Thanks for doing that little test. It was good to see that it worked exactly how i thought that it would. Your website is awesome. Thanks again.

[jacksc02]

dellis, Im glad you like it, maybe you could post it up so people can have a look?

When I get a chance I will tweak it a bit more add some smoke etc.

before any1 flames me for what i am about to say...
i think aura looks like an amazing solution to set things on fire...

but couple of weeks ago i bumped into something that almost sucked the life out of me.and these tests sere not done on some billion MHZ processors with gizzillion gigs of ram...

for any one interested ...
http://portal.acm.org/citation.cfm?id=882335

download the pdf file ...
i am sure a lot of guys know about this but just felt like refreshing this ,
after seeing "NUKE" test.

i dont mean to start a flame thing here ,cuz i know its easier to start an argument than share and learn from other people...
my 2 cents....

[dellis]

I think what you will find is that aura will have a very similar look to the rendererings when the fractal shaders are implimented. The paper is impressive but not really the kind of software that we'll ever get our hands on...unless you work at ILM.
I'm actually surprised at how quick AURA is for what its actually doing.

Don;t get me wrong i would love to gets the same kind of results they were getting in that paper....especially on that kind of hardware.

Aura already looks about as good as most of the effects in this short

Edit: BETTER

cdren99: That's really cool but did you know there is a forum dedicated to AURA now at the bottom of the main page?
