Method
This node creates a breakable copy of a 3D object using Voronoi-based splitting process. The underlying 3D object may be connected from a 3D Object node via the Object Node input, or generated as a primitive using the Shape Type parameter. The splitting process iteratively cuts the mesh and then creates multiple pieces. The Num Cuts and Num Pieces parameters control the number and size of pieces created, where larger values will cause more and smaller pieces to be created. The pieces may be grouped together via cuts or points, using the Grouping Method parameter; grouping by points produces more regular shaped pieces, where grouping by cuts creates shards. The shattering is not volumetric; instead, the shape is shattered as thin polygons which are then thickened to make 3D shards using the Thickness parameter.
The shattered mesh remains a single object, but each generated piece is assigned a different bone, allowing the pieces to be animated using bone deformation. In order to animate the shattered pieces as particles a Particle Bone Deformer may be parented to the node. Other Defomer nodes may also be connected in order to deform the shattered mesh.
Materials may be connected via the Material and Cut Material inputs, allowing different materials to be used for the original polygons and the generated cut polygons.

Outputs
This node outputs the normal transformation and translation values, but it also outputs geometry which can be Deformed or used as a mesh source by other nodes.
