Class Projection

Functions for projecting 3d points to 2d space.

Inheritance

System.Object

Projection

Namespace: UnityEngine.ProBuilder

Syntax

public static class Projection

Methods

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

Find a plane that best fits a set of 3d points.

Declaration

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

Parameters

Type	Name	Description
System.Collections.Generic.IList<Vector3>	points	The points to find a plane for. Order does not matter.
System.Collections.Generic.IList<System.Int32>	indexes	If provided, only the vertices referenced by the indexes array will be considered.

Returns

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

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

Project a collection of 3d positions to a 2d plane. The direction from which the vertices are projected is calculated using FindBestPlane(IList<Vector3>, IList<Int32>).

Declaration

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

Parameters

Type	Name	Description
System.Collections.Generic.IList<Vector3>	positions	A collection of positions to project based on a direction.
System.Collections.Generic.IList<System.Int32>	indexes

Returns

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

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

Project a collection of 3d positions to a 2d plane.

Declaration

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

Parameters

Type	Name	Description
System.Collections.Generic.IList<Vector3>	positions	A collection of positions to project based on a direction.
System.Collections.Generic.IList<System.Int32>	indexes	A collection of indices to project. The returned array will match the length of indices.
Vector3	direction	The direction from which vertex positions are projected into 2d space.

Returns

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