Using dophassubdata To Change Colors Dynamically
Jun 24th
It’s a fairly straight forward but I thought it needed to be put in video form. Dynamics and expressions in Houdini go hand in hand and this is an example of that. You can find the video tutorial on how to do this here and the result below:

Emitting Particles Using A Bounding Object And Its Normals
Jun 8th
There was a discussion on the Houdini forums that I took part in that I thought was worth not just one video tutorial but a three part series. I think it’s a really simple task but shows oh so much and is easily applicable to more complex work. What it covers is taking an object that will emit particles and dictating what points on the emitter send out particles and in what direction using a bounding object and one of the bounding object’s normals. You can find the videos and completed .hipnc file here.
Here is what the final result looks like (note that I changed the resulting file a bit to get a good flipbook result):

Animation Doodles
May 20th
I was reading Animation Mentor’s Tips and Tricks (done by Shawn Kelly in the monthly newsletter) and I’ve found it fascinating to see into the mind of an actual animator. I’ve actually never focused much on the art of animation, being interested primarily in the technical aspects of it, so these tips and tricks are interesting because it shows the amount of work that goes into actually doing character animation. After reading certain tips I thought I would do some rough thumbnails of an animation which lead to some general doodling (the results of which I’ve posted below). I’m not finished with all of Shawn’s tips but they certainly spark my interest in trying my hand at character animation. Luckily, Houdini has a toon character asset that is rigged quite nicely, so I might mess with that for starters.
Constraining Cloth Addendum
May 19th
I was so caught up with showing how you can get your grouped points output to a group node I didn’t show the easier way to stitch cloth with the stitch constraint (and an issue that may arise). So instead of calling do-overs and doing the whole video again just to add that, I’ll just do a 2 minute supplement to the video which you can find here.
Constraining Cloth
May 12th
After seeing the videos that Sidefx puts out (1, 2), I am obviously left with the thought that I’m no where close to the level of “real” Houdini users. But I still trudge along learning what I can when I can, and sharing it here with everyone. Behold then my super beginner video on constraining cloth to a bar… using two different methods!
Here’s an example of the second method using the flipbook:
