Hi, is there a way to show an overview of the nodes with errors in a subnet without trawling through it?
Houdini Indie and Apprentice » (Solved) How to surfsect odd geometry?

Hi, thanks. I think I'm going about this the opposite way to most people - learning Houdini before I learn to model, so I was curious about how you actually close geometry like that. I'm wondering if there's an easier way than just selecting the points, putting them into groups and adding extra polygons from them. Loft, stitch, patch, join, skin, cap, fuse… none of them seemed to help much.
Do you know of a way to renumber points?
For my work, it's best if I can get only one shape at a time, so the cookie isn't the best thing for me to use. Instead, I use a ray SOP to project radially from a point. I've attached another file.
This also has the advantages of a) working on most geom types, including metaballs, and b) you can just alter the number of divisions in the Circle SOP to reduce or increase the detail of your xsection.

Hi,
I've been doing something similar, and it's turned out to be more complicated than it should be. One thing to try:
Start by making sure the input is a closed, polygonal surface (Convert SOP).
Next, put down a Cookie SOP, with the geom wired into the 1st input, and a large grid into the 2nd input.
Switch the mode from Boolean to Crease, and you should end up with an intersecting surface.

Hi,
Is there a way to force a MIDI out CHOP to cook when it isn't being observed in motion view?

I had to do something similar to #1 recently, and have attached a file with one way to do it. There might be a simpler way.
Can't help you much with #2 but I think the foreach SOP could be very helpful there too.
#3 - The hou.lvar(“…”) function gives you local variable values, e.g. lvar(“PT”) and lvar(“PR”). (You don't need the “hou.” prefix in parameter expressions

Hi, I'm running v10.0.734, and would like to know if v11 (which doesn't run on my system) shares the following behaviour:
I'm using the ray SOP to transfer attributes from points on a surface, using the ‘Import attributes from hits’ option. The problem is that string attributes are not transferred. Please could you check the attached Houdini file in H11, and let me know if the texturemap attribute on the Ray SOP is blank for all points?

Hi,
Is it possible to use a COP's output instead of an image file for texturing objects?

Hi, I've recently spent some time trying to do this, and would also recommend trying out TouchDesigner (http://derivative.ca/) [derivative.ca] first instead.
MIDI out from Houdini (at least in Windows) seems pretty buggy, and there's no OSC output.

WhoDjiniThat's great, cheers!dinkleberry
I'd like to get my hands on some medical volumes,
Have a look at The visible Human project [nlm.nih.gov], you could probably find what you are looking for…
They possibly have raw data available.
….
Had some time for a clkoser look…
Here [nlm.nih.gov] are their terms and conditions. They seem to have also raw data from their GE MRi & CT scanners.
Hope that's usefull for you !

I'd be interested to find out how you get on. I'd like to get my hands on some medical volumes, but don't know if there's any freely available (online or otherwise) for a non-medical research project. Where's your data coming from?

I've finally got Chip Collier's OSC CHOP Node (http://sourceforge.net/projects/houdini-osc/) [sourceforge.net] to build and work on my system, Houdini 10.0.734 on Vista. Unfortunately, I was after an output CHOP, not an input CHOP as this is, so I won't be doing any more work on it. I'm uploading a built DSO, my modified source files (I just changed two lines), along with a couple of libs used to build, and a dll needed to run (which I put in c:\houdini\bin). See OscPack - http://www.audiomulch.com/~rossb/code/oscpack/ [audiomulch.com]
and Pthreads-Win32 - http://sourceware.org/pthreads-win32/ [sourceware.org]
There are a couple of things that I noticed:
- Port is hardcoded to 7000, so don't bother changing that parm.
- The node cooks whenever the frame counter increments (I think it would be nice to cook every time a relevant OSC message is received)
I'll do my best to answer any questions about it, but I'm not the author.
