Hello
Encouraged by the partio and partio4maya projects I decided to come up with a small tool called partio43delight.
It is a renderman procedural loading particle caches with partio, and rendering them as RiPoints() primitive.
There's also a maya plugin that allows you to render partioVisualizers straight out of maya.

Take a look:
http://bitbucket.org/mfratczak/partio43delight
http://vimeo.com/47202017

The precompiled package can be downloaded here (tested under windows)
https://bitbucket.org/mfratczak/partio4 … _08_09.zip

The tool is in it's early days and needs testing and bugfixing - be warned.
I'm doing this in my spare time, but will try to fix and polish it in upcomming weeks.

Have fun and let me know if you find it usefull or hit a bug.

This looks useful, I'll keep up with this (I know I'll need it eventually). Good work!

Nice! Thanks Michal for sharing this. I have used partio4Maya as well and that's an excellent tool too. This is also a great addition to the partio toolset. Thanks again :)

Changing the "Replicate" to anything besides 0 crashes renderdl. Guess its not supported yet.

EDIT : Just read the lines on your source page that these are unimplemented.

But the other parameters like radius, velocity scale work really nicely. I especially like the option of rendering as blobbies! Superlike :)

Another problem I'm coming across is while lighting the particles. I'm using the maya visualizer node and have added the light linking parameters to both the viz node and the light using the attribute node and object sets. Neither raytrace nor depth/deep shadow map seem to work.

Glad you like it :)
I'll try to provide example scene soon.

very interesting .. will test it out. What particle caches is it reading in? ptc or RIB?

If ptc, how are you caching them out?

I just started to build a small pipeline around RIB-particles - but always would be more interested in ptc

ogre · 2012-08-14 01:19:05

It's based on Partio lib, so it reads what partio provides (https://github.com/wdas/partio/tree/master/src/lib/io)
I haven't tested it extensively, but I know BIN crashes partio, so avoid that one.
Unfortunatelly partio does not handle 3delight's PTC.
I'll have to run some tests to see which format is most efficient.

ogre · 2012-08-15 12:28:48

ok, I added a simple particle multiplication option. This is very limited implementation with just constant radius. More is comming soon.

Woooo! The replication option is just what I need, going to try this out ASAP!
Thanks for developing this.

Apparently your system is missing some DLLs, zlib.dll or microsoft redistributable DLLs.
Try installing those and let me know.

smallpixel · 2012-08-16 16:33:51

i installed them ,and still getting the same error ,

any links i could follow to make sure i install the right things?

Thanks Michal

I'll have to get some 'fresh' machine to make sure installation is smooth and easy ...
If you don't want to wait, you can use http://www.dependencywalker.com/ to check what DLLs are missing, and put them intoC:\Windows\System32

Delighter · 2012-08-17 05:05:37

I tried it out, cool stuff!
I have two questions

1. Is it possible to assign materials onto the particles?
2. How does one get shadow on the particles? I managed to get them to cast shadows on the ground plane, but not themselves.

smallpixel · 2012-08-18 12:00:40

Hi Michael,
i was able to load the plugin in maya ,i found the missing dll .and it worked,

i have tryed to render some simple rib files but renderdl kept on erroring with this message
# Rendering 3delightScene.rib ...
3DL ERROR A2011: RiProcDynamicLoad: 'partio43delight_procedural' is not a shared
library (system error: A dynamic link library (DLL) initialization routine fail
ed.)

im trying to render a prt file,
im using 3delight 1.0.50 x64

any help would be much appreciated

Thanks
Saber

You can assign an external (sdl) shader through 3delight relationship editor.
Try standard plastic shader to get selfshadowing.

What DLL was that? zlib.dll ?

According to docs:
A2011 RiProcDynamicLoad: ’libname’ is not a shared library (system error: syserror)
Search paths may be in incorrect order or the file is corrupted.

Are you sure the dll is in searchpath defined in rib/renderpass ?
Today I checked it on other machine, and it worked OK...

Let me know :)

smallpixel · 2012-08-20 12:08:35

All sorted now ,

thanks for help Michal

Delighter · 2012-08-21 01:28:46

Cheers Ogre!

It works :)
Will there be support for hypershade shaders in the future?

Thanks.

Thanks.

Latest partio4maya is implemented as shape, instead of locator, so it should work.
But this depends not on me :)

Delighter · 2012-08-21 06:27:56

Ok, I'll just have to test some more then.
Thanks for your efforts!
