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.

Connect the name of a polygon mesh object to emit particles from
|
Particle Emitter Settings
|
Turn this of to emit from the polygon mesh's surface instead.
|
|
The number of particles to emit.
|
|
The size of particles. This is primarily for display and debugging in the viewports, because you probably don't want to render
them.
|
|
The shape of the particles. Again, this is for display.
|
|
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
|
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.
|
|
How the rate is interpreted when a filter attribute is specified:
- : the number of samples specified by the Rate value will be generated from the area where the filtering condition is satisfied.
- : 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
|
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 controls plane to display per particle to avoid visual clutter.
