Syntax

public static class ARPlaneMeshGenerators

Remarks

These static class provides ways to generate different parts of plane geometry, such as vertices, indices, normals and UVs. You can use these functions to build an ARPlane Mesh object.

Methods

GenerateIndices(List<Int32>, List<Vector3>, Single)

Declaration

public static bool GenerateIndices(List<int> indices, List<Vector3> convexPolygon, float areaTolerance = 1E-06F)

Parameters

Type	Name	Description
List<System.Int32>	indices
List<Vector3>	convexPolygon
System.Single	areaTolerance

Returns

Type	Description
System.Boolean

GenerateMesh(Mesh, Pose, Vector3, Vector3, List<Vector3>, Single)

Generates a Mesh from the given parameters. The convexPolygon is assumed to be convex.

Declaration

public static bool GenerateMesh(Mesh mesh, Pose pose, Vector3 center, Vector3 normal, List<Vector3> convexPolygon, float areaTolerance = 1E-06F)

Parameters

Type	Name	Description
Mesh	mesh	The Mesh to write results to.
Pose	pose	The Pose of the plane, in session space.
Vector3	center	The plane's center, in plane-space.
Vector3	normal	The plane's normal, in plane-space.
List<Vector3>	convexPolygon	The vertices of the plane's boundary, in plane-space.
System.Single	areaTolerance	If any triangle in the generated mesh is less than this, then the entire mesh is ignored. This handles an edge case which prevents degenerate or very small triangles. Units are meters-squared.

Returns

Type	Description
System.Boolean	True if the mesh was generated, False otherwise. The mesh may fail to generate if it is not a valid polygon (too few vertices) or if it contains degenerate triangles (area smaller than areaTolerance).

Remarks

convexPolygon is not checked for its convexness. Concave polygons will produce incorrect results.

GenerateUvs(List<Vector2>, Pose, Vector3, List<Vector3>)

Declaration

public static void GenerateUvs(List<Vector2> Uvs, Pose pose, Vector3 normal, List<Vector3> vertices)

Parameters

Type	Name	Description
List<Vector2>	Uvs
Pose	pose
Vector3	normal
List<Vector3>	vertices
