100 million particles

[vlado]

Hi guys,

Here are some interesting results from the work of our developer team for V-Ray 3.0

This is amazing!
So this will work with PhoenixFD too?

[vlado]

We are in fact rendering some more interesting images where we simulate 148 million particles with Phoenix FD and then render them out with V-Ray proxies.

Best regards,

Will you make them public? Very interested to see them!

Cheers.

I raise you 200 mil :]

Can you make literally physically accurate metalic car paint with all the milions of flakes to be actually particle geometries ? : ]

[super gnu]

coo-el. we just need a way to merge particle passes into a single proxy like in krakatoa and well be set.

There are some images here (you might have to scroll down a bit):

Thats amazing.... I soo wanna see a car paint with flakes as geo now Is this something I can generate in vray/maya/particle system or its just lab test?

from the page you posted:
"The particles below were generated by Phoenix FD, and then converted to a .vrmesh file. 148 million particles were simulated for 60 frames; the resulting .vrmesh file was nearly 350 GB of data."
is the vrmesh in this case bigger than the combined phoenix cache files?
is there anyway to decrease these file sizes?

[vlado]

Phoenix caches were 107 GB. However, the Phoenix caches only store the particle positions and the simulation grid (which is relatively low-res). The .vrmesh files store the particle positions, colors and velocities and radii, so that's a bit more than about 3 times more data per particle. It should also be noted that Phoenix itself could not render that many particles.

Thanks for the fast reply!

Ok, Phoenix can simulate it but I guess its not able to even show the particles in the viewport? or is it a memory problem at the render time?

It can show them in the viewport but rendering, especially with motion blur, is a bit challenging. Here the ability of the .vrmesh files to load only pieces of the whole file comes in very useful.
