ICE compound that outputs a boolean attribute for each edge that lies on a polygon mesh boundary. Fabricio's page features an illustrated making-of and embedded videos for this addon.

Note this is deprecated for SI 2012 and up because these versions have factory attributes for boundary components.

The compound internally builds a camera frustum and translates fxtree tracking data to 3d data. Two things you should know before using: be sure to align camera and interest Y position before applying the compound. (that's because frustum rotation is not being calculated yet) change the image resolution inside the compound to fit your dimensions. (didn't find a way of retrieving image resolution right inside the ice tree)

...Being using this one a lot in shots involving simple 2d tracking (no rotation, or hand keyed rotations) for object replacements, prop attachments, etc..

Compound will be stored under Tools > Tracking. Also have a look at the introduction vimeo video.

(Quoting from Guillaume Laforge's blog)Before Christmas, I was speaking around a coffee with Marc-André Belzile (Mr Softimage SDK and many more) about a little viewer to see our ICE particles simulation without opening Softimage and then he created this nice open source project ! - A Python viewer to scrub your icecache, Nice :)

Generates a point for each segment of each strand. WARNING It can generate a lot of points if you've got large point count and/or large strand segments count.

Deletes particles which fall below a specified ground surface. Surface can be curved etc. Useful for culling particles and rigid body instances which escape collisions and are no longer visible.

Use in an unsimulated ICE tree to create a series of instances which match their instance masters precisely. Very powerful! Use to create shattering or exploding effects, RBD simulations like a classic »car through brick wall« and so on. Usage: Pre-fragment a model, place the fragments into a group as instance masters, and supply the group to this compound.... then you can animate in a simulated ICE tree.

V1.1 - Can be used for a variety of neat effects, including the world's least efficient toon shading... Filters an emission to only emit particles which are perpendicular to a supplied 3d vector, if this 3d vector is the camera's global position, then the particles appear to be emitted only at the silhouette of the emitter geometry. Because it's an emission filter, large emission rates are often needed. Usage: plug into »execute on emit« port of emitter, supply an input vector (usually a camera position or a null position).

V1.1 - Clamps velocities which exceed a user threshold. Highly recommended, a frequent-use compound. Handy for keeping particle simulations from getting overly energetic. Usage: Apply just prior to simulation node, set threshold.

local backup: limit_velocity.1.1.xsicompoundp

V1.1 - Similar to »surface force« except particle mass is taken into account. Use to create orbiting effects or to act as gravity in certain situations where gravity vectors are not of constant direction (meteor shards and debris hitting a planet surface, escher-esque fantasy environments etc.)

ooShrinkWrap is an ICE compound that recreates part of the functionality of the built-in ShrinkWrap operator. As an added feature, it has a shaping fcurve that allows additional tuning of the resulting deformation.

ooRelax is an ICE compound that relaxes a mesh. Mesh relaxing means averaging (smoothing) its points and reprojecting the result on the original unsmoothed polygons.

Requires ooSimpleSmooth to be installed.

ooSimpleSmooth is an ICE compound that smooths a mesh. Mesh smoothing means moving each point towards the average location of its neighbors.

SlipstreamVX introduces a new method of simulating fluids to the VFX artist community. Rather than employing a voxel simulation method that uniformly divides up space whether or not anything interesting is happening, the patent pending SlipstreamVX focuses on the interesting aspects of the fluid, the turbulence, wherever it is and it represents in explicitly.

This innovative approach to fluid simulation gives SlipstreamVX two unique and powerful benefits: First, SlipstreamVX does not limit its fluid simulations to any type of bounding box. Fluid simulations are free to go where they want. You can have detail where you want it [..]

An ICE compound that simulates the pin art effect.

Sliding Skin is a set of ICE compounds that enables sliding the one mesh along surface of another, underlying mesh. Here I've used it for skin sliding, but it can be used anywhere where you need the sliding effect. Instead of well known approaches, such as shrink wrapping or constraining envelope's deformers to NURBS surface, it using UVs of underlying mesh. Transformation offset between nulls is sampled to UVs, then it's projected back to point positions. Which means, that just one pair of controllers can slide the mesh along whole surface of underlying mesh, without stretching. Also, there is no need for enveloping, so you can use it together with Softimage's envelope or any other deformation operator. Whole setup is connected to mesh only by applying the ICE tree. Performance rely on mesh resolution, cutoff distances, viewport display
