InsertAndRetriangulateContext Class

Context for repeated insertion of new points in a graph.

  • Initial graph should have clean outer boundary. (e.g. as typically marked with HalfEdgeMask.EXTERIOR)
  • After each insertion, the current "position" within the graph is remembered so that each subsequent insertion can reuse that position as start for walking to the new point.

Methods

Name Description
insertAndRetriangulate(xyz: Point3d, newZWins: boolean): boolean    
moveToPoint(movingPosition: HalfEdgePositionDetail, xyz: Point3d, announcer?: (position: HalfEdgePositionDetail) => boolean): boolean    
reset(): void Reset the "current" position to unknown state.  
resetSearch(xyz: Point3d, maxDim: number): void    
searchForNearestEdgeOrVertex(xyz: Point3d): HalfEdgePositionDetail Linear search through the graph  
searchForNearestVertex(xyz: Point3d): HalfEdgePositionDetail    
create(graph: ): InsertAndRetriangulateContext Static Create a new context referencing the graph.  

Properties

Name Type Description
currentPosition Accessor ReadOnly HalfEdgePositionDetail Return a (reference to!) the current position in the graph  
graph Accessor ReadOnly Query the (pointer to) the graph in the context.
