Struct PlaneBoundary

Container for the boundary of a detected planar surface. This is specific to Magic Leap because the polygon describing the boundary may be concave, and may contain holes.

Syntax

public struct PlaneBoundary : IEquatable<PlaneBoundary>

Properties

holeCount

The number of holes in this boundary.

Declaration

public int holeCount { get; }

Property Value

Type	Description
int

polygonVertexCount

The number of vertices in this boundary's polygon.

Declaration

public readonly int polygonVertexCount { get; }

Property Value

Type	Description
int

valid

Whether this PlaneBoundary is valid. You should check for validity before invoking GetPolygon(Allocator, ref NativeArray<Vector2>), GetPolygon(Allocator), GetHole(int, Allocator), or GetHole(int, Allocator, ref NativeArray<Vector2>).

Declaration

public bool valid { get; }

Property Value

Type	Description
bool

Methods

Equals(object)

IEquatable interface. Compares for equality.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
object	obj	The object to compare for equality.

Returns

Type	Description
bool	true if obj is of type PlaneBoundary and compares equal with Equals(PlaneBoundary).

Overrides

ValueType.Equals(object)

Equals(PlaneBoundary)

IEquatable interface. Compares for equality.

Declaration

public bool Equals(PlaneBoundary other)

Parameters

Type	Name	Description
PlaneBoundary	other	The PlaneBoundary to compare against.

Returns

Type	Description
bool	true if all fields of this PlaneBoundary compare equal to other.

GetHashCode()

Computes a hash code suitable for use in a Dictionary or HashSet.

Declaration

public override int GetHashCode()

Returns

Type	Description
int	A hash code suitable for use in a Dictionary or HashSet.

Overrides

ValueType.GetHashCode()

GetHole(int, Allocator)

Get the polygon representing a hole in this boundary. The 2D vertices are in plane-space.

Declaration

public NativeArray<Vector2> GetHole(int index, Allocator allocator)

Parameters

Type	Name	Description
int	index	The index of the hole. Must be less than holeCount.
Allocator	allocator	The allocator to use for the returned NativeArray. Must be Allocator.TempJob or Allocator.Persistent.

Returns

Type	Description
NativeArray<Vector2>	A new NativeArray allocated with allocator containing a set of 2D vertices in plane-space describing the hole at index.

Exceptions

Type	Condition
InvalidOperationException	Thrown if valid is false.
InvalidOperationException	Thrown if allocator is Allocator.Temp or Allocator.None.
ArgumentOutOfRangeException	Thrown if index is less than 0 or greater than or equal to holeCount.

GetHole(int, Allocator, ref NativeArray<Vector2>)

Get the polygon representing a hole in this boundary. The 2D vertices are in plane-space.

Declaration

public void GetHole(int index, Allocator allocator, ref NativeArray<Vector2> polygonOut)

Parameters

Type	Name	Description
int	index	The index of the hole. Must be less than holeCount.
Allocator	allocator	The allocator to use if polygonOut must be resized. Must be Allocator.TempJob or Allocator.Persistent.
NativeArray<Vector2>	polygonOut	The resulting polygon describing the hole at index.

Exceptions

Type	Condition
InvalidOperationException	Thrown if valid is false.
InvalidOperationException	Thrown if allocator is Allocator.Temp or Allocator.None.
ArgumentOutOfRangeException	Thrown if index is less than 0 or greater than or equal to holeCount.

GetPolygon(Allocator)

Gets the polygon representing this boundary. The 2D vertices are in plane-space.

Declaration

public NativeArray<Vector2> GetPolygon(Allocator allocator)

Parameters

Type	Name	Description
Allocator	allocator	The allocator to use for the returned NativeArray. Must be Allocator.TempJob or Allocator.Persistent.

Returns

Type	Description
NativeArray<Vector2>	A new NativeArray containing a set of 2D points in plane-space representing a boundary for a plane. The caller is responsible for disposing the NativeArray.

Exceptions

Type	Condition
InvalidOperationException	Thrown if valid is false.
InvalidOperationException	Thrown if allocator is Allocator.Temp or Allocator.None.

GetPolygon(Allocator, ref NativeArray<Vector2>)

Gets the polygon representing a plane's boundary, and, if successful, copies it to polygonOut. polygonOut is resized or created using allocator if necessary. The 2D vertices are in plane-space.

Declaration

public void GetPolygon(Allocator allocator, ref NativeArray<Vector2> polygonOut)

Parameters

Type	Name	Description
Allocator	allocator	The Allocator to use if polygonOut must be recreated. Must be Allocator.TempJob or Allocator.Persistent.
NativeArray<Vector2>	polygonOut	A NativeArray to fill with boundary points. If the array is not the correct size, it is disposed and recreated.

Exceptions

Type	Condition
InvalidOperationException	Thrown if valid is false.
InvalidOperationException	Thrown if allocator is Allocator.Temp or Allocator.None.

Operators

operator ==(PlaneBoundary, PlaneBoundary)

Compares for equality. Same as Equals(PlaneBoundary).

Declaration

public static bool operator ==(PlaneBoundary lhs, PlaneBoundary rhs)

Parameters

Type	Name	Description
PlaneBoundary	lhs	The left-hand side of the comparison.
PlaneBoundary	rhs	The right-hand side of the comparison.

Returns

Type	Description
bool	true if all fields of this PlaneBoundary compare equal to the fields of the other PlaneBoundary.

operator !=(PlaneBoundary, PlaneBoundary)

Compares for inequality. Same as !Equals(PlaneBoundary).

Declaration

public static bool operator !=(PlaneBoundary lhs, PlaneBoundary rhs)

Parameters

Type	Name	Description
PlaneBoundary	lhs	The left-hand side of the comparison.
PlaneBoundary	rhs	The right-hand side of the comparison.

Returns

Type	Description
bool	true if any field of this PlaneBoundary is not equal to the same field on the other PlaneBoundary.
