This is a Kinetic Energy compound that lets you apply this type of energy to a lot of different attributes. It should be handy for more realistic vfx work.

With this compound you can influence the object's weightmap by its distance to another geometry (Polymesh or Nurbs). The compound calculates vertices and surfaces by their distance to the geometry in the ICE tree. Check out the controls for the radius and the falloff strength for individual settings.

Adds to a weight map from proximity to another geometry and fades this value over time. This version also adds values to an already existing weight map, connected to 'Original weight map'. For a longer period of time to accumulate, you need to increase 'time before fade' value.

Adds to a weight map based on proximity to geometry then fades it out over time. think wetness map. for this compound to work the object must have a weight map connected. Many thanks to Patrick Boucher, as there is no way I would have got this compound to work without his assistance.

This ICE compound allows for the rotation of a point about any arbitrary input position, which can act as a dynamic pivot.

Quick example of doing a planar projection using ICE - because you can.

This calculates mesh density in the object coordinate space. With the default settings, all edge lengths >1 produce a density value of 0; as the edge lengths get closer to 0, the density value will approach 1.

This is an ICE compound node that computes surface curvature for a polygon mesh. You get positive output values for convex (outward) curvature, negative ones for concave (inward) curvature. Includes an update by Harry Bardak, who exposed the mode parameter.

Part of »rray's Surface Property ICE nodes« . Measures surface tension. Tension can be used as source data for various rendering and deforming effects like blending of a wrinkle texture map or a squash-and-stretch effect (shown in example Tension-squash-and-stretch.scn).

Consists of two compounds: »tension from« computes and stores the average edge lengths of each point's connected edges. »tension to« computes the average edge lengths again (placed at a higher point in the stack, i.e. executed later) and compares them to the results stored earlier by »from«.

The difference is processed so it best represents the local surface tension at each point. Every deform in the stack between »from« and »to« gets registered by the »to« node and is output as the scalar tension value for the points. The UI has an fcurve that lets you further control the output of »tension to«. X is the computed tension (negative X is compression). Y is output. If you don't want tension values to go above 1 or below -1 use the default f curve which clips off tension values above and below these values.

For measuring only stretching, move the first key to (0,0) and leave the second at (1,1). For compression-only move the first key to (-1,1) and the second key to (0,0). For accessing tension values from the render tree, you'll have to go through a weight map (ICE attributes can't be accessed for polygon meshes currently). This is demonstrated in Tension-rendering.scn

Note: When rendering, tension values look much better (are smoothed) when the mesh is subdivided (+)

It is often useful to make sure your particles do not overlap. This simple compound will delete particles that overlap within a certain distance. It has a simple rule to decide which of the overlapping particles to keep. There's also a debug option to show you which particles it will remove.

This compound does the same thing as the Particle Cube but instead of using the XSI primitive it generates the points inside the compound. It is a good starting point for creating procedural layouts using groups of particles within a cloud. Particles created in the set have a GroupID so you can have multiple-sets per cloud.

This plug-in lets you remove the initial state set on particle simulations in ICE. It will add a menu item called »Reset Initial State« in the Simulation > ICE > Edit menu. It assumes you have used the set initial state command to create an initial state for your simulation.

This is a simple compound that returns the center of the bounding box of the current object (self).

Twists an object around an axis. You can either use a default twist axis (X, Y or Z) or use a manipulator such as a null to define it.

This is the exact same deformation as the built-in twist deformation found in XSI with all the advantages ICE has to offer: multi-threaded, open for modification, etc.

You can easily add this compound to a menu by using Add Operator to Menu found in the User Tools menu of the ICE Tree view. If called from a menu, you will be automatically prompted to pick a manipulator object (optional).

This compound emits new particles from any location on a surface or curve. Plug this compound's Emit output into the ICETree node. This compound should be plugged in to the first port of the ICETree node because you usually need to emit particles before any other node or compound can be evaluated.

Locations can be generated by the geometry query nodes. For example, by using a raycast node, you could cast a ray on a geometry and emit from that intersection point. You can also use this node to emit from every point of a geometry by connecting a Get Data node on the PointLocation attribute of the emitter (e.g. »Cube.PointLocation«) to the Emit Location port.

This compound lets you set the transparency of particles based on an FCurve and its age percentage. Handy for making particles fade in and out, among other things.

Takes a set of cubic bezier control points and evaluates a single point — or multiple, if fed an array into the »T« port. Can be used with the »Fit Cubic Bezier Curve« compound.

Takes an array attribute of Vector2/3/4 points and fits a cubic bezier curve onto them, resulting in another array of points that can be used with »Evaluate Cubic Bezier Curve«. Great for smoothing a set of points, like a spine or a tail.

Simple Compound that removes duplicates in an array. E.g.: 12,3,3,3,3,6,6,4 becomes 12,3,6,4 — It only eliminates uninterrupted sequences, i.e. in 13,4,7,4,2 the »4« will not be eliminated. For eliminating all dupes, see the Deduplicate compound. Works for any data type.

Usage example: Can be used in conjunction with Halfdan's Bezier tools in order to eliminate double or triple points that would break the computation otherwise.
