Robert Kelly's sop-solver-tool

Hey Peeps!

I am releasing my sop-solver-tool, making the sop solver easier than the for each sop!

http://www.sidefx.com/exchange/info.php?fileid=695&versionid=695

No help no example files but it could be a while till I get around to those so i thought i should let the world have it sooner rather than later.

The basic work flow is like this...

In sops you have the geometry that is the first frame state, plug this into the first input. next press the button "Make New Sop Solver Feedback" this purple colored node will be the top of the feedback loop providing the geometry from the previous frame. the sops that you place between the feedback node and the second input are applied each frame. going back to frame one after changing the feedback loop will make the cached geometry recook again. Careful not to select or otherwise make the feedback sops display when you are trying to simulate the sop-solver-tool otherwise it will not feedback the geometry until you return to the first frame and only display the sop-solver-tool or any node after it.

Any changes you make to the geometry in the feedback loop should be small because this will happen each frame and large movements will rapidly send your geometry far.

A simple example is to get a poly sphere with a frequency of 9 and then pipe it into the first input of the sop-solver-tool. Next press the button "Make New Sop Solver Feedback" this purple colored node will be the top of the feedback loop providing the geometry from the previous frame. then after the feedback sop add a mountain sop with a very subtle height amount, followed by a smooth with 1 iteration. select and display the sop solver and hit play. it should bulge out over time. This is a simple task that doesn't do much more than what could be done with regular sops but i will leave that for you to discover, until I get around to making example files.

I actually created a node pretty much exactly like this about 2 years ago. Basically the same however it was to play around with editable nodes inside an asset. Instead of piping the network to run into an input I just had a geometry subnetwork inside the asset that the SOP Solver pointed to. It worked pretty well. I completely forgot about it and don't think I've actually used it since then. The Feedback SOP which is available through the Proto Install also does the same thing.

I would say my tool is more of an interface fix of the sop solver so it's quick and easy to use at a whim, Rather than the status quo of having to go in 3 levels to edit the sops. when the sop solver is used inside sops it makes sense but when you only want the feedback feature it is an interruption in the workflow.

I installed the feedback sop and it works but it's a bit raw and could use a few more settings to control it.
