Physics and particles

Turning objects into particles so far only works on full objects. A shattered object can be disintergrated as well but complications arise when the object is put in the physics engine.

Object to Dust

Going off what Doug suggested I started looking at particles to create a more procedural deconstruction of the object. Disintegration of the object didn't take too long to create and managed to get simple objects breaking into dust reasonably quickly. I may not have a full object with disintegration ready for the progress report document but with this I can show where Iam heading towards.

Shattered obect with Particle

Here I was able to able to apply particles to objects when shattered to mimic dust.

Controlled Model Shatter

I finished my silo model and tried to create a controlled shatter effect. Still somewhat in the testing phase the edges are not as refined as I'd like. To get to this level of control and detail took some time seperating objects and re-fractructing. Getting it perfect will take some time but is very possible.

The image shows the selected breaks ones falling to the ground. I havent added the other parts of the model to the solver but that should be easy.

Breaking Problem Solved

I had a problem with the breaking of objects with the voronoi shatter where the pieces would shatter correctly but the origanal object remained. Trouble shooting the problem was difficult due to the lack of relvent froums and resources.

I managed to work out that the copies were extra groups made with the shatter sop. Houdini wouldn't allow me break the groups without deleting the object so I spent some time trying to work around it. I couldn't change the group but i was able to add a group mask to filter the groups in the physics solver and remove the copy. With this I can complete the model and be in control in the breaking of the object.

Adding Rigid Bodies to shatter

Managed to add the other objects into the rbd solver so the shattering object can break off other ones.

Asset Shatter

This is the shatter effect extending onto the beginning of one of my detailed assets.

Voronoi Shatter

Here is a working shatter on an object in houdini. Somehow there is a duplicate object which becomes visable after the break. I am working on a seperate file for the detailed mesh which will have a detailed break. This file will be used for working out the way I can break the object and how they can be connected with other objects.
