Okay Im starting this thread to get peoples reactions, comments and tips on using SOuP's solver node and how to get the best out of it.

Unfortunately the example scenes do not work 100% on OSX which has been an ongoing issue with Maya I believe and not SOuP itself so we just have to live with that for now.
But, one can still view the node editor which is kind of helpful in that you can see how the scenes are built but limited because any changes are not updated in the view.

So moving forward, for me the solver is pretty hard to control and get nice animated effects from. My only success story is being able to reproduce the ice crystals examples by accident which is basically a 2D effect with post face extrusion after the Solve.outGeometry - looks really cool!

My attempts on the more 3D stuff end up looking like a mess really quickly with tonnes of interpenetration and nothing looking as good as Peters examples. Ive tried using range in the group node to reduce the numbers of components in an edge extrusion for example and then use the resolvePointCollisions to try and push points away from each other but I still cant prevent interpenetrations.

I tried using the resolveSelfIntersections inside the solve loop (and tried after the Solve.outGeometry as well) but get a software crash everytime.

So what are your experiences good and bad, have you found any successful workarounds, any tips you can share so we can take this node to the limits?
Look forward to your comments.


My success story (pretty easy really)

I am working on a new version and part of the effort will be to take a look at what is going on with the solver node on OSX.
Will report shortly.

The setup of the nodal networks that behave properly over multiple iterations can be challenging. Couldn't think of how this can be improved really. Any suggestions will come in handy.

Hi guys,

Jeremy, I think it would be very useful for those of us who are learning without much time, to show another screenshot with the connections, mode "2".

Thank you!

Just an update. The scenes archive now contain the the original solve scenes which play nicely with OSX. Thanks for looking at those Peter and updating. I still turn off the Multisampling anit-aliasing toogle for Viewport 2 to speed up viewport actions for reference.

Managed to come up with some half decent results.

Just wondering if you can somehow animate components from the group node, for example I am using the range option but instead of ALL the components animating at once, Id like the component selection to grow over time. I have a feeling Ive done this before or it can be done but Im not getting it right now.

Looking pretty.

Wonder if you can use bounding objects in "point cloud" mode and use geometry created from the previous step.
Or use weight map + arrayDataContainer that goes into the group node in "weight map" mode.

Yeah though about arrayDataContainer node, thanks Ill try that.

Having loads of fun with the solver node now!

Ha, that's cool. I didn't think about it before.

When you are done with your fun activities, can you please send me the files, so we include them in the example scenes archive ?

sure, just sent you some mail. I have a couple of other ideas evolving from this like collisions so will see how that turns out, so far the solver makes a pretty cool city scape as well! Will update today.
