Cluster to WeightmapAuthor: Felix Geremus
As the name implies it converts clusters to weightmaps. Whats nice though is that it accepts all types of clusters (point,polygon,edge) and adds the ability to grow and/or smooth the resulting weightmap. Remember that you have to create the weightmap before you create the Icetree to make this work.

Create Copies along CurveAuthor: Felix Geremus
I don't think there is an easy way to do this with the build-in topology compounds plus it has some other nice features:

supports both open and closed curves nice controls to interactively position, scale and rotate your copies on the curve copies will be evenly spaced along the curve the copies nicely align to the curve, you shouldn't run into any problems with flipping normals on s-shaped curves. transfers UV's

Neural NetAuthor: Felix Geremus
Another take on motiongraphic's currently most popular effect: emits particles and connects them with strands. This one is

pretty fast works both in a simulated and non-simulated environment two modes of stand creation: closest points & random turbulize and grow the strands

Emit from PolygonsAuthor: Felix Geremus
This compound is thought to be used in a non-simulated environment and the emitter mesh should ideally consist of quads only. The idea behind this compound was to quickly create coral like structures by emitting instances from polygon centers and scaling them according to the polygon they've been emited from. This helps to prevent instances from penetrating each other, and also results in a more natural, organic look [..]

Quantize ValuesAuthor: Felix Geremus
This one is a bit techy, but proved useful to me. It takes a set or array of scalar values and spits out quantized values based on a quantization step. An image (hopefully) explains more than thousand words :)

Thanks Felix,

particularly loving Neural!
I'm trying it and I've a question: I want to turbulize the particles and animate the grow parameter at the same time.
It works, but the growing acts weird. The grow works only when the turbulize is near to zero, like from 0.016 to 0 and at that point there's no much time to see the grow transition.
I'm connecting a Turbulize Mesh to Execute on Emission, I guess I'm trying to turbulize the particles in the wrong way.

Your're right, I've updated the download link with a new version which should work better.
Don't know what kind of effect you wan't to achieve, but remember that if you turbulize the particles "on emission", your only modifying their initial position, so they won't move or anything like that. If you want to turbulize the particles movement, you have to plug the turbulize into a normal execution port. In this special case though it's recommendet to modify the pointpositions before the emission, otherwise you will end up with something like this:

In this case you modify the point positions after the strands have already been drawn, thus you get these strange connections to the location where the point used to be. Modifying the point positions before the strands are drawn works fine:

Mossman,

thanks a lot for the update. From your screen grab I see you're using a simulated Ice tree whereas I'm using a non-simulated one.
Anyhow, I've started from scratch using the latest update you posted and everything it's working fine now. I'm also adding some Mootzoid EmTools compounds and some other Scatter Tools compounds, glad to see that everything works fine together.

Seems this post and is long since forgotten...hopefully someone comes back to life ;)

Any chance this would work if I pulled in another point cloud to drive Neural net? Like another particle Sim? And if so how would one go about that? As the emitter is looking for a geo as a souce?
