Can you post an example file to test? It would make it easier to check out what is happening in Houdini.

There is some info in the notes for this gallery item:

It uses Wren along with a GI pass - Houdini's compositing nodes are used to bring the images together.

The young lady is a model from the Toronto area. For the photo shoot she had to climb and then jump off a short ladder a few hundred times. Our rights to the image were for one version of Houdini (H9) only therefore we are not able to use the image any more. I would have liked to create a desktop image of it but that would mean reacquiring the rights which is not something we are considering right now.

Houdini_Apprentice09
How can you possibly state that it is fixed, when the only time you can get the DAILY VERSION RELEASES is when you are logged in as a fourm member? It clearly hasn't been changed so non fourm writers can access the latest build and SEE the fixes!
Actually if you go to this page:
http://www.sidefx.com/index.php?option=com_download&task=apprentice&Itemid=277 [sidefx.com]
you have access to the latest production build which was updated yesterday. (build 10.0.465). Of course it looks like you are registered as a forum member so you must have already tried one of these builds. Are your SL problems taken care of now or are you still having issues?

Greg Hermanovic was one of the founders of Side Effects Software. At one point he wanted to go in a different direction and founded derivative which creates touchdesigner. Houdini and touch share the same base technologies although they have serve different markets.
The purpose of the tech evening in Toronto is to show the community where this technology is now.
Robert
PS - we will probably not be recording this presentation. We try to record as many as possible but usually they are recorded on another day so that the presenter can focus on the audience during the tech evening.

Houdini Lounge » Melting an Object

In a 3D world article I wrote a tutorial that used fluids to “reverse” melt a character. Here is the video that came out of that article:
http://www.youtube.com/user/houdini3d#p/a/u/0/KrplrAH9Hrk [youtube.com]
This used particle-based fluids and you could easily reverse the process to melt a “particle” version of your character then use the particle fluid surfacer to put them back together again…
Here is the issue with the article from 2007:

If these are personal artistic projects and not commercial projects then you can use Apprentice HD. The resolution of rendered images is limited to 1920x1080 but I would imagine that that would be big enough for you.

Soothsayer
It's a lot deeper than other apps and that makes it pretty hard and long to learn and to become productive. Sometimes you stumble over seemingly simple things that have incomprehensible answers (you wanna move a point along the normal? Why, it's simply P = P+N*scaling_factor!). Some people never get up after those falls and return to their old soft. So, growing a new userbase is hard and I think that's part of the reason why it's so cheap.
If you put down a vopsop then dive down to VOPs you can put down a Displace along Normal node then feed it into P. This will move your points along the normal. MMB-click on the “amount” input and choose “Create Parameter” and this will promote the displace amount up to the geometry level.
If you are using the edit sop (simply editing points) then you can RMB-click on the handle and choose “Toggle Peak Handle” which will let you pull points along their normal.
Robert
PS - the reason it is so cheap is because we want to support students and artists working on personal projects and because you can't use it for commercial purposes…

They aren't really fused together in Houdini. One way to separate them is to display the vertex grips (from display bar) and then you can more easily grab only one vertex when several are overlapping.
Another way I do this is to toggle my selection type. I select a bunch of faces then convert the selection type to vertices - now because the faces only use some of the vertices I am now focused on ONLY those vertices associated with the selected faces. I can now move these around and they will separate from overlapping vertices.
Sometimes I will select faces the convert to vertices then using the Ctrl key remove the vertices that I don't want from the faces then I can move the remaining vertices to separate them.

Houdini Indie and Apprentice » Geometries won't MOVE, they just won't budge!

The one's that won't move all have something in common. They are extracted objects. I had a car geometry that was only a few object nodes. I selected each piece of the car, and extracted it to a new object node. now when i try to parent those extracted car parts to something, they don't move. even if i don't parent them, they still don't want to move. but the original node that the parts were extracted from is fine, it moves around.
The extract tool works by grabbing the geometry with a object merge node. Now the object merge node is by default designed to lock down the transform of that shape and therefore ignore any transforms applied at the object level. There are two options -
First you can dive down the the geometry level and on the object merge node set transform to None - this will object merge the geometry but ignore transformations from the original object and will allow you to position the extracted object and it will update. The problem is that if your original object had been transformed then the extracted object will appear offset.
The second option is to go down to the geometry level and click on the lock flag on the object merge node. This will let you move the extract object at the object level but you will lose your connection to the original geometry - therefore if the original model is reshaped then that will not be picked up by the new one.
Houdini Lounge » New HDK Documentation

As many of you know, the Houdini Developer’s Kit is a comprehensive set of C++ libraries which give studios and third party developers access to Houdini's API. Instead of being limited to a subset of the API like most SDKs, the HDK provides virtually the same level of access available to Side Effects developers.
With the HDK, you can create plug-ins to customize virtually all aspects of Houdini. Some examples include:
- add custom expression functions
- add custom commands to hscript or hython
- add custom operators (SOPs, DOPs, POPs, etc)
- add output to 3rd party renderer, geometry or games engine
- add custom lighting or atmospheric effects
The new HDK docs were written with a practical philosophy in mind. First they identify the main task a programmer would encounter when customizing Houdini using C++, eg: data I/O, creating new operators, extending the UI, rendering. Next, each process is explained in-depth and well-documented sample code is provided to illustrate the application of key concepts. Node organization in Houdini is then discussed along with how to work with nodes and their parameters, and how to create new nodes in each of Houdini's operator contexts. The new docs also cover the main HDK classes such as OP_Network and SOP_Node, as well as, important utility classes such as Houdini’s very efficient Matrix classes, Multithreading classes and Vector Math (VM) classes.
Our developers have been working hard to make this material available and will continue to add to and enhance this material over time. With so many studios looking for ways to incorporate Houdini into their pipeline, these new HDK docs will play a key role in that process.
To access the new docs, visit http://www.sidefx.com/docs [sidefx.com]

Houdini Lounge » Question about unlimited render nodes
- rmagee
- 1182 posts

When you purchase either Houdini Master or Houdini Escape we generally give about 5 tokens by default. If you want more then you simply request it from your sales manager and we give you as many as you need.
The Mantra tokens render ifd files which can be created by your Master/Escape license. If you don't want to tie up your interactive license for this task then you may want to consider one or more Houdini Batch licenses to generate ifds for you. The Batch licenses can also do other things like run simulations and run scripts which makes it worth having it around.

how about using a .ai file? You just need to make sure that compression is turned off and you don't output a PDF and you should be able to get your geometry into Houdini. I usually use Illustrator CS3 format.
If this doesn't work then post your .ai file here and we will test it out.
Robert
PS - remember that the geometry comes in really big into Houdini. Press “spacebar - a” to show zoom out and see the geometry.

“HQueue is initially being released for LINUX users as a free public beta. The planned release of HQueue is July 2009, when it will also be available for Mac OS X and Windows systems. HQueue will be made available as a free add-on to commercial licenses of Houdini Master and Houdini Escape. ”
This is from the press release here:
http://www.sidefx.com/index.php?option=com_content&task=view&id=1478&Itemid=55 [sidefx.com]
HQueue will therefore not be available for Apprentice or Apprentice HD customers.
