Flatten(List<IParametricCurve2d>)

Declaration

public static List<IParametricCurve2d> Flatten(List<IParametricCurve2d> curves)

Parameters

Type	Name	Description
List<IParametricCurve2d>	curves

LaplacianSmooth(IList<Vector2d>, Double, Int32, Boolean, Boolean)

Declaration

public static void LaplacianSmooth(IList<Vector2d> vertices, double alpha, int iterations, bool is_loop, bool in_place = false)

Parameters

Type	Name	Description
IList<Vector2d>	vertices
Double	alpha
Int32	iterations
Boolean	is_loop
Boolean	in_place

LaplacianSmoothConstrained(GeneralPolygon2d, Double, Int32, Double, Boolean, Boolean)

Declaration

public static void LaplacianSmoothConstrained(GeneralPolygon2d solid, double alpha, int iterations, double max_dist, bool bAllowShrink, bool bAllowGrow)

Parameters

Type	Name	Description
GeneralPolygon2d	solid
Double	alpha
Int32	iterations
Double	max_dist
Boolean	bAllowShrink
Boolean	bAllowGrow

LaplacianSmoothConstrained(Polygon2d, Double, Int32, Double, Boolean, Boolean, Boolean)

Constrained laplacian smoothing of input polygon, alpha X iterations. vertices are only allowed to move at most max_dist from constraint if bAllowShrink == false, vertices are kept outside input polygon if bAllowGrow == false, vertices are kept inside input polygon

max_dist is measured from vertex[i] to original_vertex[i], unless you set bPerVertexDistances = false, then distance to original polygon is used (which is much more expensive)

[TODO] this is pretty hacky...could be better in lots of ways...

Declaration

public static void LaplacianSmoothConstrained(Polygon2d poly, double alpha, int iterations, double max_dist, bool bAllowShrink, bool bAllowGrow, bool bPerVertexDistances = true)

Parameters

Type	Name	Description
Polygon2d	poly
Double	alpha
Int32	iterations
Double	max_dist
Boolean	bAllowShrink
Boolean	bAllowGrow
Boolean	bPerVertexDistances
