Constructor & Destructor Documentation

LevelSetFracture ( InterruptType *  interrupter = nullptr )

explicit

Default constructor.

Parameters

interrupter

optional interrupter object

Member Function Documentation

void clear ( )

inline

Remove all elements from the fragment list.

void fracture	(	GridPtrList &	grids,
		const GridType &	cutter,
		bool	segment = false,
		const Vec3sList *	points = nullptr,
		const QuatsList *	rotations = nullptr,
		bool	cutterOverlap = true
	)

Divide volumes represented by level set grids into multiple, disjoint pieces by intersecting them with one or more "cutter" volumes, also represented by level sets.

If desired, the process can be applied iteratively, so that fragments created with one cutter are subdivided by other cutters.

Note

The incoming grids and the cutter are required to have matching transforms and narrow band widths!

Parameters

grids	list of grids to fracture. The residuals of the fractured grids will remain in this list
cutter	a level set grid to use as the cutter object
segment	toggle to split disjoint fragments into their own grids
points	optional list of world space points at which to instance the cutter object (if null, use the cutter's current position only)
rotations	optional list of custom rotations for each cutter instance
cutterOverlap	toggle to allow consecutive cutter instances to fracture previously generated fragments

GridPtrList& fragments ( )

inline

Return a list of new fragments, not including the residuals from the input grids.
