Pulldownit for Maya > Shatter It!, Voronoi-based pre-cutting

Shatter It is a pre-cutting tool, it is able to generate jaggy fragments, much more realistic than classic polygonal fragments. it is Voronoi-based because this scheme has showed to be the best mathematical pattern for brittle fracture. Its technology allows to pre-cut a 3D model in hundred of shards in seconds, in addition the fragments generated plug easily in the Pulldownit solver to perform simulation in a fast and stable way..


The current pre-cutting tools in most 3D platform consist basically in clipping planes and fill holes modifiers; this could be enough for modelling purposes, but definitively quite poor for dynamics where you would like to pre-fracture an object in hundreds of shards to obtain believable results when simulating. Shatter It!, the new pre-cutting tool by Thinkinetic, is designed thinking in dynamics needs; it is Voronoi-based because this scheme has showed to be the best mathematical pattern for brittle fracture, its workflow is surprisingly easy, just select a polygonal object from the viewport, input the desired number of fragments and hit Shatter It! button, concavity or holes are not an issue anymore; Its technology is able to pre-fracture a high resolution model with fine detail in seconds. In addition, UV mapping is also supported. Shatter It! introduces different cutting styles, Uniform, Local, Path based, Radial and Wood Splinters. Radial style generates a perfect pattern for breaking-glass-like effects, Path-based style allows for the creation of long dynamics cracks and Local style for creating localized damage on corners and surfaces, besides you can combine all of them at your pleasure by continue cutting the generated shards until achieving the desired look. New Jagginess deformer allows to modify the surface of the fragments, converting flat geometry into rough faces and twisted edges, getting a high-realistic look for stucco, stone or concrete materials. Although Shatter It! tool can be used independently of the rest of the plug-in, Its mayor advantages comes when simulating the prefractured object with the Pulldownit solver; the shards created plug easily in dynamics, also knowing Voronoi scheme generates mostly convex shards, Pdi takes advantage of this fact to speed up the computation of fracture.
