Syntax

[Obsolete("ARPlaneMeshGenerators has been deprecated in AR Foundation version 6.0. Use ARPlaneMeshGenerator instead.", false)]
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 methods to build an ARPlane Mesh object.

Methods

GenerateIndices(List<int>, List<Vector3>, float)

Generates a List of indices from the given parameters, forming a triangle fan. The convexPolygon is assumed to be convex.

Declaration

[Obsolete("GenerateIndices has been deprecated in AR Foundation version 6.0.", false)]
public static bool GenerateIndices(List<int> indices, List<Vector3> convexPolygon, float areaTolerance = 1E-06)

Parameters

Type	Name	Description
List<int>	indices	The List to write results to.
List<Vector3>	convexPolygon	The vertices of the plane's boundary, in plane-space.
float	areaTolerance	If any triangle in the generated mesh is less than this, then the entire mesh is ignored.

Returns

Type	Description
bool	True if the indices were generated, False if a triangle whose area is less than areaTolerance is found.

Remarks

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

GenerateMesh(Mesh, Pose, NativeArray<Vector2>, float)

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

Declaration

[Obsolete("GenerateMesh has been deprecated in AR Foundation version 6.0. Use ARPlaneMeshGenerator.TryGenerateMesh instead.", false)]
public static bool GenerateMesh(Mesh mesh, Pose pose, NativeArray<Vector2> convexPolygon, float areaTolerance = 1E-06)

Parameters

Type	Name	Description
Mesh	mesh	The Mesh to write results to.
Pose	pose	The session-space pose of the mesh.
NativeArray<Vector2>	convexPolygon	The vertices of the plane's boundary, in plane-space.
float	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
bool	True if the mesh was generated, False otherwise. The mesh might 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, List<Vector3>)

Generates a List of UVs from the given parameters.

Declaration

[Obsolete("GenerateUvs has been deprecated in AR Foundation version 6.0.", false)]
public static void GenerateUvs(List<Vector2> Uvs, Pose pose, List<Vector3> vertices)

Parameters

Type	Name	Description
List<Vector2>	Uvs	The List to write results to.
Pose	pose	The session-space pose of the mesh.
List<Vector3>	vertices	The vertices of the plane's boundary, in plane-space.
