Syntax

struct FVertexConstraint

Remarks

FVertexConstraint is a constraint on a triangle mesh vertex

Variables

		Name	Description
	bool	bCanMove	Can this vertex be moved
	bool	bCannotDelete	Is this vertex permanent (i.e. cannot be removed by topology-change operations).
	int	FixedSetID	Vertices marked as "CannotDelete" but sharing the same FixedSetID can optionally be collapsed together (ie in Remesher)
	IProjectionTarg...	Target	Vertex is associated with this ProjectionTarget, and should be projected onto it (ie in Remesher)

Constructors

	Name	Description
	FVertexConstraint()
	FVertexConstraint ( IProjectionTarget* Target )
	FVertexConstraint ( bool bCannotDelete, bool bCanMove, int FixedSetID )

Functions

		Name	Description
	void	CombineConstraint ( const FVertexConstraint& OtherCons... )	Combine the incoming constraint with this constraint.
	FVertexConst...	FullyConstrained()
	bool	IsUnconstrained()
	FVertexConst...	PermanentMovable()
	FVertexConst...	Unconstrained()

Constants

Name	Description
InvalidSetID	Value for FixedSetID that is treated as not-a-fixed-set-ID by various functions (ie don't use this value yourself)
