Syntax

public static class MeshValidation

Methods

ContainsDegenerateTriangles(ProBuilderMesh)

Returns whether any face on a mesh contains degenerate triangles.

Declaration

public static bool ContainsDegenerateTriangles(this ProBuilderMesh mesh)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The mesh to test for degenerate triangles.

Returns

Type	Description
bool	True if any face contains a degenerate triangle, false if no degenerate triangles are found.

See Also

RemoveDegenerateTriangles(ProBuilderMesh, List<int>)

ContainsDegenerateTriangles(ProBuilderMesh, IList<Face>)

Returns whether any of the specified faces contains degenerate triangles.

Declaration

public static bool ContainsDegenerateTriangles(this ProBuilderMesh mesh, IList<Face> faces)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The mesh to test for degenerate triangles.
IList<Face>	faces	The faces to test for degenerate triangles.

Returns

Type	Description
bool	True if any face contains a degenerate triangle, false if no degenerate triangles are found.

See Also

RemoveDegenerateTriangles(ProBuilderMesh, List<int>)

ContainsDegenerateTriangles(ProBuilderMesh, Face)

Returns whether the specified face contains degenerate triangles.

Declaration

public static bool ContainsDegenerateTriangles(this ProBuilderMesh mesh, Face face)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The mesh to test for degenerate triangles.
Face	face	The face to test for degenerate triangles.

Returns

Type	Description
bool	True if any triangle within the face contains a degenerate triangle, false if no degenerate triangles are found.

See Also

RemoveDegenerateTriangles(ProBuilderMesh, List<int>)

ContainsNonContiguousTriangles(ProBuilderMesh, Face)

Checks whether any triangles in a face are disconnected (non-contiguous).

Declaration

public static bool ContainsNonContiguousTriangles(this ProBuilderMesh mesh, Face face)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The mesh that owns the face to test.
Face	face	The face to test.

Returns

Type	Description
bool	True if the face contains split triangles; false if the face is contiguous.

EnsureFacesAreComposedOfContiguousTriangles(ProBuilderMesh, IEnumerable<Face>)

Ensures that each face in the specified set is composed of contiguous triangle sets. If a face contains any non-contiguous triangles, this method splits them into as many faces as necessary to ensure that each group of adjacent triangles compose a single face.

Declaration

public static List<Face> EnsureFacesAreComposedOfContiguousTriangles(this ProBuilderMesh mesh, IEnumerable<Face> faces)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The mesh that contains the faces to test.
IEnumerable<Face>	faces	The faces to test for non-contiguous triangles.

Returns

Type	Description
List<Face>	A list of any newly created faces as a result of splitting non-contiguous triangles. Returns an empty list if no faces required fixing.

RemoveDegenerateTriangles(ProBuilderMesh, List<int>)

Iterates through all faces in a mesh and removes any triangles with an area less than float.Epsilon, or with indices that point to the same vertex. This function also enforces the rule that a face must contain no coincident vertices.

Declaration

public static bool RemoveDegenerateTriangles(ProBuilderMesh mesh, List<int> removed = null)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The source mesh.
List<int>	removed	An optional list to be populated with the removed indices. If no degenerate triangles are found, this list contains no elements.

Returns

Type	Description
bool	True if degenerate triangles were found and removed; false if no degenerate triangles were found.

RemoveUnusedVertices(ProBuilderMesh, List<int>)

Removes vertices that no face references.

Declaration

public static bool RemoveUnusedVertices(ProBuilderMesh mesh, List<int> removed = null)

Parameters

Type	Name	Description
ProBuilderMesh	mesh	The source mesh.
List<int>	removed	An optional list to be populated with the removed indices. If no vertices are removed, this list contains no elements.

Returns

Type	Description
bool	A list of deleted vertex indices.
