Detailed Description

template<class TSurface>
class Felt::Polys< TSurface >

Polygonisation for a spatially partitioned level set surface.

Holds child Poly::Single objects that are dynamically created, updated and destroyed as the surface changes.

Call notify each time the surface is updated to keep track of spatial partitions that need (re)polygonising.

Alternatively call invalidate to mark the whole isogrid for (re)polygonisation.

Call march to go through tracked changes, updating the polygonisation of flagged spatial partitions.

After each march, call changes to get the position indices of partitions that were updated.

Member Typedef Documentation

Child

template<class TSurface >

using Felt::Polys< TSurface >::Child = typename Traits::Child

Child grid type.

Constructor & Destructor Documentation

Polys()

template<class TSurface >

Felt::Polys< TSurface >::Polys ( const TSurface &  surface_ )

inline

Member Function Documentation

changes()

template<class TSurface >

const PosIdxList& Felt::Polys< TSurface >::changes ( ) const

inline

Get list of partitions that were updated.

Returns

list of position indices of partitions that were repolygonised in the last march.

invalidate()

template<class TSurface >

void Felt::Polys< TSurface >::invalidate ( )

inline

Add all active poly childs and isogrid childs to change tracking for (re)polygonisation.

march()

template<class TSurface >

void Felt::Polys< TSurface >::march ( )

inline

Repolygonise partitions marked as changed since last polygonisation.

notify()

template<class TSurface >

void Felt::Polys< TSurface >::notify ( )

inline

Notify of an update to the surface in order to track changes.

This should be called whenever the surface is updated to ensure that eventual re-polygonisation only needs to update those spatial partitions that have actually changed.
