In combination with the node above, you can also use the Voronoi Fracture Points SOP to generate points for it to use. You can create these points with scatter SOPS, or points from volume SOPS. The first is for the mesh you would like to fracture, and the second input is for the points it needs to fracture the mesh. As well as your RBD simulation as a whole. There are also other tools that go along with the Voronoi fracture SOP to improve its use. The node is also on it’s 2.0 version(As of 2021) so there have been several improvements to it. As well as generating fractures in concrete. The Voronoi Fracture SOP is great for small scale RBD sims. It is an ideal node when working with multiple constraints, glues, and meshes. The RBD Material Fracture SOP allows for you to create wood, concrete and glass fractures. These fracturing methods can be found in the RBD Material Fracture SOP, and in the Voronoi Fracture SOP. This allows you to generate accurate fractures for different types of objects. RBD also has several different material fracturing options. While passive objects can collide with active objects, they don’t move. Active objects can interact with collisions and forces. It handles objects as if they were hard objects, such as buildings, bricks, or other structures. This system allows for the motion, fracturing, and collision of objects to be handled within solvers. RBD, more commonly known as Rigid Body Dynamics, is a system inside Houdini.
