Member Function Documentation

void enableDithering ( bool  on = true )

inline

ValueAccessor getAccessor ( )

inline

GridHandle< BufferT > getHandle	(	double	voxelSize = 1.0,
		const Vec3d &	gridOrigin = Vec3d(0),
		const std::string &	name = "",
		const OracleT &	oracle = OracleT(),
		const BufferT &	buffer = BufferT()
	)

Return an instance of a GridHandle (invoking move semantics)

GridHandle< BufferT > getHandle	(	const Map &	map,
		const std::string &	name = "",
		const OracleT &	oracle = OracleT(),
		const BufferT &	buffer = BufferT()
	)

Return an instance of a GridHandle (invoking move semantics)

void operator()	(	const Func &	func,
		const CoordBBox &	bbox,
		ValueT	delta = ValueT(0)
	)

Sets grids values in domain of the bbox to those returned by the specified func with the expected signature [](const Coord&)->ValueT.

Note

If func returns a value equal to the brackground value (specified in the constructor) at a specific voxel coordinate, then the active state of that coordinate is left off! Else the value value is set and the active state is on. This is done to allow for sparse grids to be generated.

Parameters

func	Functor used to evaluate the grid values in the bbox
bbox	Coordinate bounding-box over which the grid values will be set.
delta	Specifies a lower threshold value for rendering (optional). Typically equals the voxel size for level sets and otherwise it's zero.

void sdfToFog ( )

inline

Performs multi-threaded bottum-up signed-distance flood-filling followed by level-set -> FOG volume conversion. It also changes the GridClass to FogVolume.

Warning

Only call this method once this GridBuilder contains a valid signed distance field

void sdfToLevelSet

(

)

Performs multi-threaded bottum-up signed-distance flood-filling and changes GridClass to LevelSet.

Warning

Only call this method once this GridBuilder contains a valid signed distance field

inline
