Fracturing/DMM?

[rohtie]

Hi, I study informatics at the university of Oslo.

I was wondering if newton features fracturing or Digital Molecular Matter, or is going to do so in the future?

core 300 do in fact has voronoi fracturing

Very nice!
Can this be done to local parts of a mesh?
For example a wall, where only one area breaks.

[Julio Jerez]

It could but I have not implement that featore yet.

In fact is ie quiet simple, basically the wold hae to be populeate by interior points,
then a control volumen is specified adorn the wall,
then teh vodoein patition is created,
the for each comve part, we clip teh voroni conve again the wall bounary,
the result is teh demotion decomposition of the wall,
the entire mode is saved with a graph data struture that keeps track of the adjacengy.

If you look at the videos, I made an complete destrutible level but at the time I did not have the cunvex hull in four dimension rotine to create a nice solid convex decompositions.
instead I used plane clipping, but the prosses is the same using convexes.

Voronoi clipping produces a very nice decomposition beacause the debrie mesh has the property that on the surface
each convex solid can be detached from the data struture by translating it alone a plane inscident to a himesphere plane of the solid.
this lead to very nide demolition with zero clipping,

here is an older implementation of the plane clipping method

Your sample there looks very good!
So if I use voronoi-fracturing instead of plane clipping,
it will look even better?

Anyway I really look forward to use newton dynamics,
thanks for the help

So as far as I understood on these video samples voronoi-fracturing was used?
