I presume you use the BASH shell in linux and you login as a normal user. The files you should be editing are in your home directory and called .bashrc and .profile (and yes, their names do begin with a . ).

attach the three nodes to the a switch sop. In the select input field type $F-1. Now if I am not mistaken you should have a three frame render output. Use the Wren-sop in /out to render wireframes.
Never tried it myself but this is how i would do it…
Good luck

There is a nice DVD from CMIvfx.com that's about…procedural cities. I think you find a lot of answers there.

Good luck and post some results on odforce!
Duh, and I did forget to mention that there was/is this guy who made a nice American like grid-city with just 42 nodes…You can find his files on Odforce too.

and I was just about to post this link http//www.tyanpsc.com/
Blame it on Antoine, he started posting links to computers to drool over…
About rendering, I think you are right about dual cores vs. more cpu's when it comes to rendering. Two computers each with one cpu is probably faster than a dual cpu system (read that some time ago in an article somewhere on the net, the conclusion page only wink ) In the article I posted you can see that the athlons do very well when it comes to rendering. AMD still has the fastest access to memory which is probably what you want with rendering. So memory bandwidth is a main factor when it comes to speed.
About buying new computer “stuff”, I think your value-based approach makes perfect sense.

Maybe this link helps a bit (or probably gets you more confused)
http//techreport.com/reviews/2007q1/cpus/index.x?pg=1
It's another cpu comparison. Seems that for rendering the AMD processors do very well, for other stuff Intel has the edge. Core 2 Duo's are the latest desktop processors, Xeons are for dual cpu systems (4 cores or 2x 4 cores or 3x 3,33 cores …I dunno, it *IS* confusing these days ?).

sorry but Apples have always been overpriced…the best bang for your buck you get when you buy parts from an online retailer. Maybe the case ain't pretty but who cares it's under the desk, a place i try to avoid spending my time (i might get strangled by the cables there anyway)

or first select the things you want to group in the viewport and when it's highlighted (yellow) you TAB -> Group and then your selection is grouped. If you select points/vertices from different geometry than automagically a merge sop is added…just give it a shot!

You could put the server script in /etc/init.d and then create a symbolic link in your default runlevel directory. It should autostart then. You might need to copy some configuration files around (to for example /etc/conf.d) or even modify them a bit.
I added most of the houdini bash script to my user bash profile so i can start houdini from wherever i want. In /opt i make a symbolic link to teh houdini version i am running called hfs8. That way i don't need to update my bash profile.

thanks for the all the tips. The attribcreate trick did it and works like a charm . No need for the attribpromote sop though. I included the file.
Did try the add-facet SOP approach but that didn't produce the result I wanted; the add SOP doesn't lend itself for much scripting and since I want to make a DA, I don't know beforehand how many polygons I need to create.

I am sorry but maybe I didn't explain properly. I made a little DA that cuts up a polygon curve in single polygons (add SOP in one branch and a delete + add SOP in another branch then both branches are wired into a merge SOP).
During this process the order of the primitive numbering changes. In the single add branch I get, for example, polygons 0 till 5, in the del+add-branch I get another set of polygons 0-6. In the merge SOP you now have 12 polygons but their order is like 0 5 1 6 2 7 etc. Now I add a connectivity SOP and it does add the class-attribute (and makes the variable class, mapped to $CLASS) but the value of class is the same as the unsorted primitive number. When you use a sort SOP then it will probably do something but the result is nil, my primitive numbering is still messy.
I hope this makes things a bit more clear. If not I can post the file tomorrow.

Well seems that trick didn't work. I opened the spreadsheet on the connectivity SOP and it did add the class-attribute but in such a way that sort can't do anything with it
primitive class
0 0
1 1
2 2
3 3
etc…
My primitives are ordered like this 0 4 1 5 2 6 3 7 (aka it's a real mess). So when adding the $CLASS in the sort SOP the primitive order stays the same. I was hoping the connectivity SOP would number the polys in sequential order of “connectedness”.
I guess I am missing something very obvious here, knowing Houdini there must be a very simple way to get this done…

I have broken up a curve of polygons into single polygons. In this process the order of the polygons got mixed up (curve starts with primitive 0, then 5, then 2 etc.). I added a connectivity sop so the curves now have in the proper order the $CLASS attribute/variable. How can I use it in a sort SOP? I didn't find any Hscript commands to set the primitive number and the sort expression slider seems strange for adding expressions…(why is there a slider and not just a blank line for the expression?)

One or two handy sops spring to mind, the copy sops with copy stamping for starters. You could also use L-systems, twist sops and everything else…probably even your own vops. Houdini's proceduralism is great for this kind of work.
In respect to your other post (http//www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=7325) there are some guys on the mailing list who did some renders for Hadid. Maybe they could give some tips on modelling. I would love to have some more “architecturally oriented” modelling tutorials too but I think the folks here are more interested in blowing-things-up-tutorials.

Hi Jaideep,
if you switch to Linux keep than here are my 50cents
- you either need some Linux enthusiast, hire one or buy a distribution with support (RedHat).
- learn, learn, learn and read manuals. There are a lot of live discs for Linux. Try them and get a bit comfortable with Linux.
- For a list of all (most) Linux distributions, check www.distrowatch.com. Some Linux distro's are extremely flexible but require more knowledge/maintainance. Some Linux distro's are very easy but not flexible at all.
- for Linux on renderfarms you don't want any desktop distribution but you want something really small (like Damn Small Linux) and a recompiled kernel so you use as little resources as possible. To install it you probably need a Linux enthusiast (see above)
- you should make a list of all programs you use in your work pipeline. Do they run on windows and Linux like Houdini or are they windows only? You might end up with some Windows workstations and a lot of Linux workstations. Don't forget the computer(program)s and applications of staff and administration. (Alienbrain seems to work on Linux too, see their website)
- How is Sidefx with support for non supported versions of Linux? Do they back off or do they still offer some form of support. You could end up by choosing between RHEL4 or debian sarge.
- For workstations you don't want a windowmanager/desktop that eats all cpu-cycles so no fancy Beryll 3D effects and no KDE. There are some very lightweight windowmanagers (twm )) which are good enough to start Houdini and isn't that all you need? You mentioned Maya but i take that as a joke…
- Performance difference, probably the same as on windows, some applications are programmed better than others and use your computers resources better. There are differences between Linux distribution when it comes to speed/effiency but i wouldn't bother with them for the moment. Not until you are comfortable with your new OS.
- As dsedov said organization is everything. (for windows, Linux or any other OS)
- You can build whatever tool you like on Linux with different GUI toolkits like QT (which can also be ported to windows), OpenGL and GTK, in almost whatever scripting language you desire, d, smalltalk ruby, python, perl, c, mono (.NET). What scripting language you want to use is what your developers are comfortable with.
hope there are some tips there for you…if it is a bit incoherent it's because i had too much coffee and am really craving for sleep and whiskey…or whiskey and sleep…
