Member Function Documentation

isAbortCalculation()

virtual bool CDT::ICallbackHandler::isAbortCalculation ( ) const

inlinevirtual

Tells whether the user wants to abort the triangulation at the earliest opportunity.

Definition at line 381 of file Triangulation.h.

onAddEdgeStart()

virtual void CDT::ICallbackHandler::onAddEdgeStart ( const Edge & edge )

inlinevirtual

Called at the start of adding a constraint edge to the triangulation.

Parameters

edge	constraint that is added/enforced

Definition at line 365 of file Triangulation.h.

onAddSuperTriangle()

virtual void CDT::ICallbackHandler::onAddSuperTriangle ( )

inlinevirtual

Called when super-triangle is added.

1.Added three new vertices with indices 0, 1, 2

1. Added one a new triangle with an index 0

Definition at line 308 of file Triangulation.h.

onAddVertexStart()

virtual void CDT::ICallbackHandler::onAddVertexStart ( const VertInd iV, const AddVertexType::Enum vertexType )

inlinevirtual

Called at the start of adding new vertex to the triangulation.

Parameters

iV	index of the vertex
vertexType	what type of vertex is being added

Definition at line 358 of file Triangulation.h.

onFlipEdge()

virtual void CDT::ICallbackHandler::onFlipEdge ( const TriInd iT, const TriInd iTopo )

inlinevirtual

Called just before an edge between tro triangles is flipped.

Parameters

iT	index of the first triangle sharing an edge
iTopo	index of the second triangle sharing an edge

Definition at line 349 of file Triangulation.h.

onInsertVertexInsideTriangle()

virtual void CDT::ICallbackHandler::onInsertVertexInsideTriangle ( const TriInd iRepurposedTri, const TriInd iNewTri1, const TriInd iNewTri2 )

inlinevirtual

Called when inserted vertex is inside a triangle.

The triangle is split in three: original trianlge is re-purposed and two new triangles are added

Parameters

iRepurposedTri	index of original triangle containing the point that will be modified (re-purposed)
iNewTri1	index of first added new triangle
iNewTri2	index of second added new triangle

Definition at line 320 of file Triangulation.h.

onInsertVertexOnEdge()

virtual void CDT::ICallbackHandler::onInsertVertexOnEdge ( const TriInd iRepurposedTri1, const TriInd iRepurposedTri2, const TriInd iNewTri1, const TriInd iNewTri2 )

inlinevirtual

Called when inserted vertex is on an edge.

Two triangles sharing an edge are split in four:original triangles are re-purposed and two new triangles are added.

Parameters

iRepurposedTri1	index of first original triangle sharing an edge that will be modified (re-purposed)
iRepurposedTri2	index of second original triangle sharing an edge that will be modified (re-purposed)
iNewTri1	index of first added new triangle
iNewTri2	index of second added new triangle

Definition at line 337 of file Triangulation.h.

onReTriangulatePolygon()

virtual void CDT::ICallbackHandler::onReTriangulatePolygon ( const std::vector< TriInd > & tris )

inlinevirtual

Called when inserting a constraint edge causes polygon containing triangles to be re-triangulated @tris triangles in the polygon that will be re-triangulated and triangles re-purposed.
