Strand Collision Framework
updated for Softimage 2015. This set of ICE nodes simulates inter-strand collisions as well as strand self-collisions.
Fwiw the author declares it to be in a »useable enough« state —
see the demonstration video to get an impression of its speed and stability.
[..] Usage should be largely self-explanatory, with the zip containing a number of example scenes. The length correction factor before collision takes place corresponds to the bidirectional length correction in the original strand dynamics framework. Think of it was a wobbliness factor. A lot of the compounds have a Range input. These compounds are driven by various values, usually the collision force. We divide the input by the range value and clamp it between 0 and 1, so a range of 10 and an input value of 1 would give you 0.1, or a 10% effect. The lower the range the stronger the effect, with 0 disabling it completely.

Re: Strand Collision Framework
I remember seeing some tests for this stuff on Vimeo years ago. It's fantastic that you finished it and even more fantastic you are sharing it. People like you are helping to keep the golden age of ICE going. Thankyou.
Re: Strand Collision Framework
Another glaring issue... No Linux compile? It's too bad as I'd love to use it in production at work (in Softimage in Linux.)
Do you have plans of releasing the source?

Re: Strand Collision Framework
I am planning a complete rebuild to go along with a set of more advanced hair modeling tools I am working on, as such I would rather this monstrosity not spread any further
Alas, it is going to take me a while to get to it, as the modeling toolset takes precedence.
I am afraid you are going to have to wait

Re: Strand Collision Framework
This looks very promising. Thanks a lot for sharing.
Cheers!

Re: Strand Collision Framework
This is great and it seems to work perfectly for hair once the emitter is set to segments instead of capsules.
Is there a way to taper the ends?

Hey Roughy,
your strand collision framework is really amazing!
is there a way to enable selfcollision and collsion with other objets at the same time?
cheers

Re: Strand Collision Framework
You can just add a second Collide Strands compound directly beneath it, and use that to collide with any other strand geometry: http://i.imgur.com/1S97000.pngCYTE wrote:Hey Roughy,

At least it seems to work. It's been a long time since I've touched this plugin, and I have no recollection of trying this.
Pardon the belated reply; I don't visit these parts very often anymore.

Hey Roughy,
thanks alot!
