Member Function Documentation

addStart()

void MR::SurfaceDistanceBuilder::addStart

(

const MeshTriPoint &

start

)

initiates distance construction from triangle vertices surrounding given start point (they all will be returned by growOne)

addStartRegion()

void MR::SurfaceDistanceBuilder::addStartRegion	(	const VertBitSet &	region,
		float	startDistance )

initiates distance construction from given vertices with known start distance in all of them (region vertices will NOT be returned by growOne)

addStartVertices()

void MR::SurfaceDistanceBuilder::addStartVertices

(

const HashMap< VertId, float > &

startVertices

)

initiates distance construction from given start vertices with values in them (these vertices will NOT be returned by growOne if values in them are not decreased)

done()

bool MR::SurfaceDistanceBuilder::done ( ) const

inline

returns true if further growth is impossible

doneDistance()

float MR::SurfaceDistanceBuilder::doneDistance ( ) const

inline

returns path length till the next candidate vertex or maximum float value if all vertices have been reached

growOne()

VertId MR::SurfaceDistanceBuilder::growOne

(

)

processes one more candidate vertex, which is returned

setMaxVertUpdates()

void MR::SurfaceDistanceBuilder::setMaxVertUpdates

(

int

v

)

the maximum amount of times vertex distance can be updated in [1,255], 3 by default; the more the better obtuse triangles are handled

takeDistanceMap()

VertScalars MR::SurfaceDistanceBuilder::takeDistanceMap ( )

inline

takes ownership over constructed distance map
