Yes, this system config is fine.
What is the graphics card? That is the critical component.

Unfortunately no. Unless there is a huge demand for a port, no.
I would imagine the OpenGL drivers from the graphics card vendors would pose your biggest problem. Too much momentum with Linux right now.

A good RFE for the default handles. I will submit it.
Just so you know, handles can take on different colors but the whole handle adopts the color.

As you probably found out, we still support the old method of bringing in shaders. If you use the Operator Type Manager, you should be able to see all your custom shaders in the Other Scripted Operators folder.
We (SESI) converted all the default shaders in to OTL's but I still have hundreds of my VEX operators at home and they come in fine. I haven't finished converting them to OTL's.

What do you mean by “rules”? Are you using events or do you mean using expressions to derive particle groups in a group POP?
What do you mean by “set the group node to select itself”?
I am confused otherwise. A group is just a collection of particles. You mainly use groups to put in the “Source Group” fields of other POPs to work only on those groups. You do not mention this in the wind POP. Of course a negative wind with no other forces in the system will eventually place all the particles in that group. Apply another random upward force and some of the particles will leave the group.
I don't see any problem here.
Using a rule to define a group is fine. They are dynamic unless you check the “Preserve Group” option. Then the particle will remain in the group even if the rule subseuently is false for that particular particle.
Nothing is stopping you from defining another group based on another rule. Each particle can belong to as many groups as you wish to define.

This is a very specific case to handle but I see your point.
You can achieve this result but requires two steps. The first is to do what Will said and RMB on the handle then turn off local control then pull your faces. Next scale the faces back using the horizontal scale loop until you get it there. Certainly not exact or precise but close.

One way to get a chamfer is to use the divide SOPs smooth option.
Place a box SOP
Append a divide SOP
Turn everything off.
Now turn on Smooth Polygons.
You should already see the start of a chamfer happening.
Now change the weight values to 3 and 0.5 using the XCF slider. The chamfer is smaller.
If you want more divisions, add more divisions to get a softer chamfer.

Doesn't tcsh ship with all linux distro's? I thought that this would have been a safe assumption to make for our R&D.

Very good. You'd think I'd know this but I haven't used an SGI in over a year now. ops:
One thing I do know is that there is no embedded html browser for IRIX. You will get the raw HTML and no javascript. This is the direction that we are taking to deliver much of our new tutorials and orientation information.

Houdini6 does take advantage of the latest CPU features from both Intel and AMD.
This is especially true of the compositor, Halo.

I wonder if Houdini is picking up the mozilla libraries in /usr/lib, not
$HFS/mozilla. So it may be a problem with the LD_LIBRARY_PATH. What is LD_LIBRARY_PATH set to?
Do you have LD_LIBRARYN32_PATH set inherited from Irix? A long-shot but you never know.

Can you guys also tell me something about it (HDK) and how different it is from the Maya API.The Houdini HDK is the actual code used to build that particular release with tools that allow you to read the headers and build your own tools, mainly operators to be used seamlessly in Houdini. Good C++ coding skills are required.
I believe the Maya API is not the actual code but a language that can be used to build tools that interface with Maya. It is very well documented and it needs to be as this is the only option for many studios.

It's your graphics card. Matrox doesn't have a very good record at developing robust OpenGL drivers in the past. Houdini requires a pretty complete OpenGL driver implementation.
Please see the Side Effects web site for approved graphics cards or ask the list right here. I use a Quadro 4 750 and is a good solution.
As a workaround, you can disable the hardware OpenGL and use the software OpenGL that comes with windows by setting the following environment variable in the Windows sysetm preferences that you can access in different ways depending on wether you use NT, win2K, or XP:
HOUDINI_OGL_SOFTWARE
and set it to a value of 1
Just remember to remove the variable if you get another graphics card.

Technical Discussion » particles interaction with displacement shaders
- old_school

i am using a procedural displacement shader. how would i do it with this?
One idea to create a uv texture map from a procedural is to use the mantra -u /obj/model option in H6 in a mantra output driver's render command where /obj/model is pointing at the specific object. First ensure that the geometry has uv texture coordinates. Fork off the chain after the uv's are generated, convert to polys, apply the same shader to your regular geometry and render out.
Still in beta, works with polys only but better than nothing.

Is this linux or windows?
Houdini comes with it's own browser embedded and does not need an existing copy of mozilla installed.
The latest version of mozilla only allows one user so you may have to close mozilla in order to run the embedded browser in Houdini.
Give me what OS and I will try to help further.

Thank-you for the license output. It shows that everything is fine except that you don't have a licenses file or you do have one that is bad.
Are you root when you try to install the licenses? Perhpas try using hkey as root.
Go to /usr/lib/sesi and cat < licenses and see what is in the licenses file. Are there any license strings in there?
You can build the licenses manually by going to license.sidefx.com and reading the apprentice instructions. You will have to either use command line tools or edit the file directly cutting and pasting in the license strings very very carefully.

Check to make sure that there are no $F variable references to current frame in any of your image references to disk. Wherever there is a reference to disk, houdini sometimes inserts a $F in the filename to anticipate a sequence reference.

Is there a way to access that treshold value and implicit function?Not directly. You need the HDK (Houdini Development Kit) to do that.
As for the noise metaball field, that would be interesting but there is an alternative. i3d can interpret metaball fields and create noise saved in an i3d file. You could then sample in to the i3d field and drive stuff from that. Your own custom noise function embedded in an i3d file. You could use this to drive particle positions for example.
