Methods

FindBestPlane(IList<Vector3>, IList<Int32>)

Finds the plane that best fits the specified set of 3D points.

Declaration

public static Plane FindBestPlane(IList<Vector3> points, IList<int> indexes = null)

Parameters

Type	Name	Description
IList<Vector3>	points	The points to find a plane for. Order does not matter.
IList<Int32>	indexes	If provided, this method considers only the vertices referenced by this array.

Returns

Type	Description
Plane	The plane that best matches the layout of the points array.

PlanarProject(IList<Vector3>, IList<Int32>)

Projects a collection of 3D positions to a 2D plane. This method uses FindBestPlane(IList<Vector3>, IList<Int32>) to calculate the direction from which the vertices are projected.

Declaration

public static Vector2[] PlanarProject(IList<Vector3> positions, IList<int> indexes = null)

Parameters

Type	Name	Description
IList<Vector3>	positions	A collection of positions to project based on a direction.
IList<Int32>	indexes	A collection of indices to project. The returned array matches the length of this collection.

Returns

Type	Description
Vector2[]	The positions array projected into 2D coordinates.

PlanarProject(IList<Vector3>, IList<Int32>, Vector3)

Projects a collection of 3D positions to a 2D plane in the specified direction.

Declaration

public static Vector2[] PlanarProject(IList<Vector3> positions, IList<int> indexes, Vector3 direction)

Parameters

Type	Name	Description
IList<Vector3>	positions	A collection of positions to project based on a direction.
IList<Int32>	indexes	A collection of indices to project. The returned array matches the length of this collection.
Vector3	direction	The direction from which vertex positions are projected into 2D space.

Returns

Type	Description
Vector2[]	The positions array projected into 2D coordinates.
