Syntax

class FQueueRemesher : public FRemesher

Remarks

Extension to Remesher that is smarter about which edges/vertices to touch:

A buffer tracks edges that were affected on last pass, and hence might need to be updated
FastSplitIteration() just does splits, to reach target edge length as quickly as possible
RemeshIteration() applies remesh pass for modified edges
TrackedFullSmoothPass_Buffer() smooths all vertices but only adds to queue if edge changes enough
TrackedFullProjectionPass() projects all vertices but only adds to queue if edge changes enough

Variables

	Name	Description
TSet< int >	EdgeBuffer	Persistent buffer of edges to be processed. This buffer is filled then iterated over.
TArray< bool >	EdgeShouldBeQueuedBuffer	Whether an edge should be added to ModifiedEdges (used in async tasks)
int	MaxFastSplitIterations	Max number of passes just doing edge splits.
int	MaxRemeshIterations	Max number of passes doing full remeshing operations.
TOptional< TSet...	ModifiedEdges	Set of edges that have been modified during a given iteration.
TFunction< void...	PostEdgeSplitFunction	The function called after an edge split occurs. This function will enqueue edges in ModifiedEdges.
SettingState	SavedState

Constructors

	Name	Description
	FQueueRemesher ( FDynamicMesh3* MeshIn )

Functions

	Name	Description
void	FastestRemesh()	Converge on remeshed result as quickly as possible.
int	FastSplitIteration()	This pass only does edge splits and enqueues modified vertex neighborhoods.
void	PopState()
void	PushState()
void	QueueEdge ( int eid )
void	QueueOneRing ( int vid )
void	RemeshIteration()	This pass does all edge operations plug smoothing and reprojection.
void	ResetQueue()
void	TrackedFullProjectionPass ( bool bParallel )
void	TrackedFullSmoothPass_Buffer ( bool bParallel )
void	TrackedMoveVerticesParallel ( TFunction< FVector3d&)> ... )	Move all vertices in parallel.

Overridden from FRemesher

	Name	Description
void	BasicRemeshPass()	"Outer loop" for all remeshing operations
void	InitializeVertexBufferForPass()
void	OnEdgeSplit ( int EdgeID, int VertexA, int VertexB, const FDynamicMesh3::FEdgeSplitInfo... )	Call the function above to enqueue edges in the ModifiedEdges set.

Classes

	Name	Description
	SettingState	We occasionally want to override the user-specified choices of edge operations to achieve some sub-step of a full remesh algorithm.
