What you could do is, after having implemented what you want in processing, just add a function, that exports every “frame” to an *.obj or *.ply file and then use a file node to read in the geometry. This is only valid if and only if you are not doing some interactive stuff processing is famous/used for.
Modules for that should be available from processing's own plug-in menu, under the 3D section. Don't have it at hand right now, to be more specific.
But there is some effort involved.
BTW: VEX is more of a Domain Specific Language, where processing is more a framework based on JAVA.

Technical Discussion » [Q]: Using multiple rules in an L-System
-
- WhoDjini

Hi! Me again !
(to the remaining unscareable ones):
I have this L-System thing set up, and it works fine, so far.
Yet one thing bothers me. Here is the rule-set:
C=KfA
B=J
A=gKF
A=gKF
[[^(90)FB+(90)FB^(90)FBFB^(90)FB]
[&(90)FB+(90)FB&(90)FB]
[-(90)FB-(90)FFB]]
and a few more “A”-Rules. But it seems, the L-System SOP uses ust one of them.
How would I have to set it up, so it uses them all (either at random or maybe also with some “artistic” control.
Also I do not understand, why in the upper leftmost some of the lines are straight like constructed where others seem more “grown”. They are all just in the simple style of FJ FFJ +(90)FJ
I want to achieve a more random look. But I dislike the idea of renaming the rules and “calling” them at random from other rules.

Yeah, kinda confusing sometimes.
My thoughts if I am allowed to:
Doing it “the right way” with the python hom would be a great idea. As that has still many “not yet implemented” ‘n’ like.
And if I do not like to type in particlesystem(“x”).forces.Blah, I'd use
p=particlesystem(“x”).forces and then p.Blah…
And I would really love it, if the docs get more exhaustive at some point. More examples. Clear structure. Class/Object reference. Hint: let a “noob” do a specific task, and watch how the challenge is being approached, where needed information is expected, and also ask why…
Sometimes for an expert of a field things seem to be logical, where a not so much professional/educated one sees no sense at all…
Took me hours to get to a point where I was able to build a polygon with python. Do not ask me where the problems were, just got over it…
BTW:
Have I overseen, how to compile python nodes to *.pyc ? Not really needing it now, but nice to know.
THX for your time

I assume, you dropped the reference to your location, right?
Then you you really should see nothing, because you set the position of your object at the value of your particle's speed. Maybe you missed the jump as you pasted the reference, or as a coincidence, object was at (eg.) loaction 0 and the speed was also at 0.
Speed is movement per time. So you would need to multiply that speed by time, to get a distance.
location = time * speed
If you just paste the reference, even though it is logically a speed, houdini does not really care about. It is just a referenced value, being used in a location parameter and so is interpreted as a location.
modify your “loaction” to like:
$FF*ch(“../../Tail_2/popnet/source_first_input/vely”)
Should be better then.
Best would be, if you would be able/allowed to provide at least a small *hip with what you set up.
Anyways, I hope this helps also a bit.

Open your NVIDIA control panel and under global settings set preferred graphics controller to your NVIDIA. That should do it.

I am new to houdini and I am looking for a new laptop to work with this new software ( I know it should be the other way round, but anyways), so I did my research and could anyone help me to decide which laptop should I get?
Lenovo y50
Asus G501
New Dell XPS15 (oct 2015)
HP Omen
MSI GS60 2QE Ghost Pro 4K
*any other laptop or comments are welcome. seeking for one which is available in the UK market.
Number ONE: You really sure it has to be a laptop?? Constrained case, no expandability, you`re stuck to what you got. Often you can`t even change HDD or add RAM, and you pay quite a lot compared to same power for the desk.
If it has to be a laptop, avoid ACER, as I had 2 of them getting thermal problems just about when warranty was over.
General advise have a look at your favorite search engine, and prefer a local store where you could have a look at the hardware, regarding access covers for HDD/&RAM should not be covered with a “warranty void” seal.
Also keep in mind you can`t expand anything else than HDD/RAM without much risk.
Then your most limiting facot would be your budget. Go for i7-xxxxHQ/MQ and GTX. and as much RAM you can afford. Keep in mind that they can get only a max of 32GB.
Have a look at http://ark.intel.com [ark.intel.com] or http://www.nvidia.com/object/notebooks.html [nvidia.com] for more

I am currently suffering from rendering animated work from Houdini. I constantly receive “OpenGL Fatal Error” message when I click mantra rendering. I am currently using XPS17 L702x laptop with 1GB graphics card.
Does anyone know how to solve this problem and will a new laptop to solve this?
Or can I transfer my animation into a different software (ie : cinema 4d/ Maya) so that I could still render an animation without having upgrading my laptop into 3GB graphics card?
You should first ensure, that your laptop has no optimus/minimus, WTH that “automatic” switching of onboard/onchip and dedicated graphics is called. That seems to never work.
Second I'd suggest to upgrade your NVIDIA drivers. It should run then.
Also have a look in “Houdini Menu” ->Help ->About Houdini and then click on “Show details”. That should help you narrow your search.
I am torturing my Laptop with a GTX850M/2GB all day long, so should be it in your case too.

I would love to break the news but honestly, I think I would steal from you the surprise, H15 looks incredible.
And that means ?…
Do we get rid of that unique grayish background eventually? I`d like some really popping colours, Like Green and Red All through the UI !!!
And what disturbs me more is that wasted screen estate all for that useless toolbars 'n stuff, ya know?….

It would be nice to have a more minimal UI design, with simpler icons. I am suggesting a vector format for the icons for optimal display in high-dpi screens.
Already is the case…
After a find ${InstallDIR} –exec grep -i svg {}\; I saw
${InstallDIR}/houdini/config/Icons/SVGIcons.index
has obiously everything needed. Just had a peek with a HexEditor….

would you use it “professional” wise???
If not, then have a look at the system requirements of the intended software.
a Tesla/Quadro would have a huge impact on your budget. save this for RAM!!!! 16+GB main and 2+GB for the GPU!
And yes,a gtx680 would be OK for H12, given you get one with 2+Gb.
I am fine with a laptop i7-2670QM(8GB)>630M(2GB) at the moment.
can't tell about Adobe/Autodesk…

Sorry to tell you this, but you have to have installed Houdini 12.1 first. It registers a helper application “orbolt_url” which handles download and installation of the orbolt assets.
If you already have done this, the locate orbolt_url in the dialog firefox shows you, and there you shoould go….

I just had the same trouble on Win7_64.
Fired up Wireshark and had a look
URI: /client/get_non_commercial_license_auto.php?servername=xxxxxxxxxx&servercode=xxxxxx&version=12.1&products=RENDER-NC%3bHOUDINI-NC
then a look at
http://license.sidefx.com/get_nc_license.php [license.sidefx.com] reveals, there is no licence for 12.1 :-(
So I fired the last 12.0, let it get a licence, and retried Houdini FX (12.1) et voilá, it runs….
just felt the need to share!

I guess one main reason could be they do not share memory, and data exchange via PCIExpress is slow compared to videoram
That is what the “buzzword” NUMA is referring to. You could avoid that by partitioning your data to stay local to a compute cluster, just like you would do in rendering when building your octree. This is also the reason why doubling your horses does not imply double the horsepower, from a certain level on, the administration overhead eats up your ressources…
But your reason seems reasonable

Yes, Houdini 12 will run on that machine. No, 4 tesla cards will not make it any faster than 1 tesla card. We can make use of your GPU in H12 for a significant performance increase but we do not support multi-GPU processing at this time.
Hi chris!
I never did CUDA or other GPU parallel stuff yet, but a lot of other CPU based parallelization stuff (MPI on SPARC&PowerPC unices). Is it such a different approach, or are there any other reasons H12 will not benefit from using multi Tesla setups ?
THX !
