ICE Kine - Drive From Particles

http://vimeo.com/19362874

Near the end, Eric shows how to set the initial position to the original while being driven by particles.


If you would consider merging them which may be a bit easier,

Motion Tools

http://vimeo.com/44039628

Main focus in this build was to implement a way of controling polygons and polygon islands with points in a point cloud. Therefore enabling users to use regular ICE nodes and Motion Tools compounds to procedurally animate such elements.


emTools
http://www.mootzoid.com/learning/emTools/documentation

Vertex Islands

Initialize Island Data
Initializes the vertex island data.

Create Particles from Island Centers
Creates one particle for each island center.

Transform Islands
Transforms the vertex islands.

Getters
A bunch of compounds to get diverse island related data.
The compounds are self-explanatory.



Also to foreafter deal with islands,

There is a polygon Island selection filter that you can put on a button (while also setting as a raycast selection mode) ,

And/or as a button, you can put a proportional move preset with a 99999999 range with consider neighborhood ON so you can freely move islands around using "M".

And/or for clusters, another button to set selection mode to polygon, also raycast, with the "cluster" toggle on
(to visually select them without having to go through the explorer)
you can also toggle visibility "Unselected Clusters" (on selected objects) if some islands are clusters and others not.


To essentially treat islands or clusters as objects.
(also useful for whenever wanting to optimally deal with thousands of "objects")

Cheers,

Not sure that's true.. I tested it out on just a few random objects and they were all seperate

Oh thats handy...I didn't know about that

Hi Adrian,

 

If I read correctly...

 

Do you need to use the 
 ICE-> Kinematics->Effects->transform objects by particles,

step?

 

Once I've used Momentum's ICE controls, I then just animate the Pointcloud itself without any other steps.

hey guys, long shot but here goes

 

we have a railway track made of 'magnetic sticks and balls toy' pieces, the pieces are instanced standins (rendered in arnold, but this is not relevant)

 

we have to have the pieces fly off (in a controlled/directed manner) in a progressive way

 

i had thought to use ICE to create a particle per object, then control the pieces with these particles, so i can trigger and animate them procedurally

 

so i de-instanced the original parts, merged them, and used momentum to apply deform body, and create ICE controls (which i then freeze, i only need momentum as an easy way to create the point per object)

 

unfortunately, when i try and use ICE-> Kinematics->Effects->transform objects by particles, it takes an arbitrary object per particle, ignoring the nearest (which is what i need) thus borking the layout of the track

 

i guess what im saying in a long winded way is i'm stuck!

 

i want to have the original objects stay where they are until triggered by some ICE stuff (test inside volume then turbulize velocity/angle etc)

 

anyone have any nifty solutions to this, i 'could' just key the pos/rot of the objects, move and rotate them and offset the animation

 

but we all know what clients are like, they will want to change stuff, and this old school method will take ages to tweak

 

thanks
