Get Closest Filtered pointsAuthor: Paul Smith
Disclaimer: This is from the resourcedump thread on si-community.com so »some restrictions may apply« (but usually don't)

A compound that gets ONLY the closest points in the current pointcloud/geometry that have a »true« boolean. It's much much faster than rifling through arrays. Hopefully someone will find this useful. It works by temporarily moving the filtered points up and away on the Y axis, then the remaining points look in the area where the filtered ones got moved to. Then filtered ones are moved back to their original location. The temporary moving of them is nothing to be concerned about because you wont see it and it doesnt affect simulation.

local backup: Get closest filtered points.xsicompound

a little test on terraforming.

uses high quality viewport.

feel free to improve or create presets!

Looks good. Is the scene only for 2014, i see your signature?

yes

but i now included the shader and ice compound into the zip file. so you should be able to use it in older versions.

a small modification of the "Bezier Movement along Surfaces" compound. unfortunately i can't remember who was the author of this source...

anyway, you can now use the new compound to create strands by/through many surfaces.

spherize

Post by forton » 13 Nov 2013, 13:29

Deformer that takes a null or group of nulls and pushes the objects points outside the nulls, nulls can also be rotated and scaled, can be useful for "muscle type" deformation or correcting volumes in characters etc.

hello
i'm trying to get used to arrays. so after playing around a bit i got a "4 point 3d corner pin".

the downside is:
- only works for grids.
- you need to match the Resolution of the Grid and ICE compound manually. (is it really impossible to get or set the resolution from the geometry operator? i guess so...)

You can't just drag the green widget in to the ice tree? It works for me here, can get .subdivu and .subdivv data.

Thanks for sharing btw!

Edit: I'm using 2014sp2

that's great news!
i remember i did so too in the past. but i doesn't let me now... (SI2014 SP1)

good to know, thank you!


EDIT: "this.geom.subdivu"/"this.geom.subdivv" is the way to go with a get data!

shallow water simulation coupled with lagoa multiphysics

Post by gustavoeb » 21 Dec 2013, 03:20

For those in the need to simulate SIMPLE water interactions FAST this is a shallow (2d) water simulator coupled with Lagoa, so it does not look toooooo cheap. It cant do curls and rolling waves, but it will spit some Lagoa particles for your viewing pleasure :D
It served quite well on a little student short, so maybe it can help others. I would love to keep working in it but no time for it, so here it goes:


https://dl.dropboxusercontent.com/u/39280733/mFlow.scn

KEEP IN MIND:
1. Anything that says "Energy Conservation" is actually just a multiplier of some energy transport. So it is like other multipliers, but, if you go over 1 energy will increase instead of dissipate causing a chain reaction that can blow up the entire matrix. So use it carefully. Turn 2-way coupling off if you really need to cheat physics.
2. Use it as is, or hack it at will... I cant support it :p

PS:
There are other things that could be done to it. It could be made more physically correct. Motion transport could have more meaningful parameters like say, viscosity. Also maybe someone could implement a bottom attribute so we could calculate the actual volume and preserve it accordingly... one can dream :ymdaydream:

Thanks all for keeping it up!

>>>>>>> This is a patch for a factory file - use at your own risk!

This one allows custom ICE operators (those Peferences->Custom->ICEOperators) to be applied on each selected item instead of on just one selected item (default behavior)

2014SP1
C:\Program Files\Autodesk\Softimage 2014 SP1\Addons\ICEUserTools\Application\Plugins\ICEUserTools.vbs
(line 596)

Code: Select all

function OperatorClicked(in_ctxt)
	on error resume next
	oString = in_ctxt.source
	for each o in selection
		applyICEOp oString, o
	next
end function

sounds cool! thanks rray.

can you give an example of when or why to use those "ICEOperators" from preferences?

It's just a convenience feature. When you have an ICE tree that you want to apply to another object, just compound it up, register it by exporting, and enter the compound name in the preferences. You can just select an object, click the menu and the compound get applied to the object.

Otherwise you'd have to go through the whole create new ICE tree--->drag an drop node-->connect to execute port, deal.

This is all built in, what the patch does is just allow to apply the compound to several objects at once using the same menu.

aaand it took a while to find this thread. it was in plugins! anyway , always nice to resurect it again, here is a quick setup demo scene example of rigid body (vorlex) simulated with verlet for some ICE on ICE interplay.

from a request on the mailing list.
