Hello,

I'd like to start a thread to document some different test projects and experiments I've been doing as I get deeper into Houdini.

I have a growing folder of gifs that I'm going to post here and hopefully continue to update as I get further along. Feel free to give any feedback or suggestions, I am open to the communities comments. Thanks!

One of the first things I did was inspired by some motion graphics type effects. I wanted to displace scattered objects based on their proximity to a single point in space. As that point moved around, it would create a moving displacement. I spent some time wrestling with the idea, and eventually dove headfirst into VEX to eventually get something to work. Here are a few of those iterations:





And this is my first rendered sequence. I wanted to take something I was working on all the way to a final presentation state, so as to become familiar with the A-Z process of completing something.



The next problem I wanted to solve was to have lines grow along a surface. This took a good deal more time to figure out in Vex, but there were some helpful videos out there that gave some useful hints.
lines on a surface [vimeo.com]
swirly trails [vimeo.com]

This went through many iterations of scrapping everything and starting over, but I eventually ended up with lines that grew over a surface in the direction of a target object.


And the great thing is, once you build a system it can be used on anything


The powerful lesson here was that there wasn't a tutorial describing how to do it step by step. But I feel like I learned more by struggling through and finding the answers for myself, rather spending time searching for the perfect tutorial.

The final result:


Then I found Entagma. I started their volume series, which is very in depth and professionally put together. I made these volume growth things based on their lessons:






I will try post more when I figure out what I want to make next. Thanks for reading!

Was able to build a simple grains cloth from scratch, without using the shelf buttons, and therefore feel like I understand it a bit better. Though I still feel a little confused as to how it works. I understand that you can feed it points with lines drawn between them to act as constraints, but how do the collisions work? Is there a way to visualize those? I tried adding in the sprite spheres manually, but couldn't get them to show. The hip file is attached for who ever feels like taking a look.

This is all rnd for a mini project I had in mind involving cloth. Hopefully more on that in the future!
