This week we will try to make a destructive effect, and I will use the wooden house model I made in the first week for destructive testing.
First, we need to understand Voronoi.
Voronoi is the closest thing we have found to make some natural or destructive shapes. The way it works is basically that we spread a lot of points, and then draw a line between every two points, and this line stops where there is another line between the other points. This effect is exactly what we want to achieve in the 3D crushing process. Broken irregularities will give the effect a more realistic texture.
The first way
Voronoifracture + Explodeview node
When you uncheck Distance VDB in vdbfrompolygons, and then select Fog VDB, the state of the model will change.
Create an isooffset node. Connect the isooffset node directly to the sphere node. At this point, you can observe the change in the shape of the object.
The second way
Add scatter/grid/copy to points and attrirandomize
Modify the scale of the transformation and the uniform scale of the exploded view.
The third way
Add rdbmaterialfracture
Adjusting the value of Scatter Points in rbdmaterialfracture will increase the number of fragments.
