Build Slice Planes

This compound works with Create Basic Shatter from Point Cloud. Apply Build Slice Planes on an empty point cloud and Create Basic Shatter from Point Cloud on an empty polygon mesh. For more information, see Simple Shattering in ICE.

This compound emits particles from a polygon mesh and then calculates the positions and normals of a pair of planes pointing in opposite directions midway between each pair of particles. These planes define the boundaries of Voronoi cells and can be used to shatter an instance of a polygon mesh.

Tasks: Topology/Shattering

Output Ports: Execute

Polymesh Name

Connect the name of a polygon mesh object to emit particles from

Particle Emitter Settings

Emit From Volume	Turn this of to emit from the polygon mesh's surface instead.
Nb of Chunks	The number of particles to emit.
Particle Size	The size of particles. This is primarily for display and debugging in the viewports, because you probably don't want to render them.
Particle Shape	The shape of the particles. Again, this is for display.
Seed	This number is used as the basis for the random generation of particles. If two different particle emitters use the same seed, you may get identical results in their emission. Change the seed value to get a different random generation of particles.

Filter

Reference

The reference of an attribute to filter particle emission if Emit From Volume is off.

You can use Boolean, integer or scalar values per point, polygon, or polynode. Integer and scalar values are clamped to a minimum of 0 and a maximum of 1. A value of 0 (or false for Boolean) means the corresponding triangle is discarded from the set of emission locations. Scalar values between 0 and 1 are used as weights: a triangle will emit N% of the locations that it would have emitted without filtering where N is equal to the weight of the triangle multiplied by 100.

Rate Control

How the rate is interpreted when a filter attribute is specified:

Exact Rate: the number of samples specified by the Rate value will be generated from the area where the filtering condition is satisfied.
Proportional to Filtered Area: the number of locations specified by Rate will be generated across the entire surface or on all points, and then culled by the filtering condition.

Plane Option

Inset Factor

Controls the distance between each pair of planes pointing in opposite directions midway between each pair of particles. This ensures that geometry is not superimposed when the planes are used to create chunks. Note that if you want to use Set Data from Chunk then you must use a non-zero value.

Planes Display

Displays values that can be useful when analyzing or debugging an effect. The Plane Index controls plane to display per particle to avoid visual clutter.
