eek 5 was spent doing destruction effects. I tried to import the models I made at Maya into Houdini for the special effects. Each session was an opportunity to get new content, which really made it challenging and fulfilling for me. Rigid body breaks are a very powerful feature of Houdini. In fact, most of the core work is done in SOP, such as the breaking of different materials, constraint generation control, attribute control and wrapping object transformations, including adding detail and material rendering in post.
Voronoi is a subdivision of the space plane, characterised by any position in a polygon being closest to the example point of the polygon (e.g. a residential area) and away from the example point of an adjacent polygon. Each polygon contains and only contains one example point. Due to Voronoi’s equal division, it can be used to solve nearest points, smallest closed circles and many other spatial analysis problems such as adjacency, proximity and accessibility.

This node allows you to generate three types of fragmented concrete, glass and wood.
It has four input ports: Geometry, Constrained Geometry, Proxy Geometry and optional inputs that can be connected to additional points to control the shape of the fragments. You can directly select the three damage presets for the material type. If a constraint geometry is connected, it automatically generates constraints between fragments.
Use different display modes: The Guide Geometry option controls different display modes. The fracture geometry is the mode of all three presets. As the name implies, it shows the broken shape.


[Bullet Solver]. The Bullet Solvent DOP sets up objects to use the Bullet Dynamic Solver. This solver can use a simplified representation of the object, such as a box or sphere, or a compound of these simple shapes to compose more complex shapes. The solver can use any convex shape depending on the geometric point of the object, or it can collide objects with the emotional body of a cloth, solid or wired object.We only need to use [bullet solver].

Next, we need to use “limits”. Make a model that only breaks and touches the ground when it falls.

This is then applied to the house and the final result is the destruction of the house.
