Learning DOPS, motors, constraints etc

These are brilliant Rich. Every damn one.

I was experimenting with ways to add the spring asset I made post sim. It was a little tricky to extract the spring constraints and replace them, but I cracked it eventually. I also did a very un-houdini-like test where I just copied the spring asset a bunch of times and attached it to an old bit of geo I had lying around.

Sorry about the colors on this one. I don't really give it much thought before I hit the render button and go to bed.

I posted the hips here. As always, most have ROPs that will need to be re-rendered to see anything. I also locked the geo into the scenes, so they are heavier than usual.

I don't know if this is useful to anyone else, but I often find that I need some simple shapes to run experiments on, but I never bother to apply consistent uv's. So I started a hip file which has some common shapes in it already uv'd.

They all retain a uv size where 1m equals 0-1 in uv space. You can easily then scale the uvs after if you want a different rez. 

There's also one in there that just takes a faceted model and splats consistent uvs on each facet.

Theres loads more I want to add, but I thought I'd just make a handful and see how useful I found them.

Heres where you can get the hip - http://richardlord.tumblr.com/post/172592883216/shape-library-i-needed-a-bunch-of-shapes-that-were

I springs I really like

I found this lying around on my hard drive and wanted to throw it up so it didn't get lost. Its a simple effect with VDBs cutting away a surface, then using those cut points to render concentric circles at render time. I've seen this effect before. This is my attempt at it. Hips can be got over here. Don't forget to re-render the ROPs that generate the point data for mantra. Otherwise you'll get a black surface at render time.

Also, here's a silly rolling system - http://richardlord.tumblr.com/post/174710941301/rolling-system-silly

Heres the latest rbd experiment I did. It's some motors being driven by a sine wave at the same pace as a piece of music. The music and images line up pretty nice I think. I was surprised!

Rich, just to let you know Tumblr puts a massive data sharing wall in your website and I would dare to suggest you move your stuff somewhere else. Many of us won't be signing to Tumblr due to the privacy concerns and massive data gathering for user profiling they do.

Anyway, just though you may want to know.

Cheers

[rich_lord 243]

Ok thanks @jordibares. Wasn't a lot of thought given to where to put these when I started. Now I use it more, I should probably move to somewhere else. Any suggestions? 

[jordibares 97]

Hi Rich... maybe Medium? Weebly? Patreon? maybe even Blogger?

[rich_lord 243]

This is not really on topic given the other stuff on this thread, but I made some growth awhile back, and finally got around to animating it.

Another version of the same system.

Here's a music video I made using a bunch of the techniques from this thread.

I also moved all the tumblr example files I've been sharing onto my new website that you can find here. https://www.richlord.com/tools

This serie is brillant ! The music video is a really nice application of it for production, love it. And it's an invaluable learning ressource to be able to dive in all these hip files, thanks a lot for sharing. Looking forward to see more explorations !

[jordibares 97]

Richard, fantastic to see all those tools in production in such a cool way.. :-)

I've done some more tests with motors. This time trying to create a bunch of them procedurally at once. Getting all the name attributes to line up was a little tricky on some of them, but I understand all this so much better after doing this.

 

Getting the axis of the motors to do what I want was also a bit tricky, but I've mostly cracked it now.

 

I've put all 5 hips that make up this video on my tumblr here - http://richardlord.tumblr.com/post/139634705771/hipfile-hipfile-hipfile-hipfile-hipfile. The sims will need to be re-rendered into the ROPs for you to see anything.

 

Thanks! Hope you enjoy!

is any one having these hip files? looks like all links were broken, please share if some one have these, Thanks in advance
