Detailed Description

template<size_t N>
class rw::geometry::ConvexHullND< N >

interface for convexhull calculators on 3d point sets

Member Function Documentation

getAvgDistInside()

virtual double getAvgDistInside ( const rw::math::VectorND< N > &  vertex )

pure virtual

Calculate average distance from point inside the convex hull to its walls.

Each distance is weighted according to the wall's volume.'

Implemented in QHullND< N >.

getCentroid()

virtual rw::math::VectorND<N> getCentroid ( )

pure virtual

Return centroid of the convex hull.

Centroid is calculated as an average of face centroids weighted by face area.

Implemented in QHullND< N >.

getClosestPoint()

virtual rw::math::VectorND<N> getClosestPoint ( const rw::math::VectorND< N > &  vertex )

pure virtual

Returns the point on the convex hull closest to the vertex .

Parameters

vertex

[in] the vertex.

Returns

the closest point.

Implemented in QHullND< N >.

getMinDistInside()

virtual double getMinDistInside ( const rw::math::VectorND< N > &  vertex )

pure virtual

If the vertex is inside the convex hull the minimum distance to any of the half-spaces of the hull is returned. If its not inside 0 is returned.

Parameters

vertex

Returns

minimum distance to vertex

Implemented in QHullND< N >.

getMinDistOutside()

virtual double getMinDistOutside ( const rw::math::VectorND< N > &  vertex )

pure virtual

If the vertex is outside the convex hull the minimum distance to the convex hull is returned. If its not outside 0 is returned.

Parameters

vertex

Returns

minimum distance to vertex

Implemented in QHullND< N >.

rebuild()

virtual void rebuild ( const std::vector< rw::math::VectorND< N >> &  vertices )

pure virtual

rebuilts the hull

Parameters

vertices

Implemented in QHullND< N >.
