Syntax

public static class MeshUtility

Methods

GenerateConvexMesh(Mesh)

Creates a convex hull from the input mesh. Useful for partially hollow meshes or open hulls.

Declaration

public static Mesh GenerateConvexMesh(Mesh mesh)

Parameters

Type	Name	Description
Mesh	mesh	Mesh to convexify.

Returns

Type	Description
Mesh	Convex mesh wrapping the input mesh.

GenerateMesh(Vector3[], int[])

Generate mesh from vertices and triangles.

Declaration

public static Mesh GenerateMesh(Vector3[] vertices, int[] triangles)

Parameters

Type	Name	Description
Vector3[]	vertices	Array of vertices.
int[]	triangles	Array of triangles (indices).

Returns

Type	Description
Mesh

GenerateSimMesh(ref Mesh, ref Mesh, bool, bool, bool, float)

Generates a simulation mesh from the original mesh with optional processing steps. Processes the mesh according to the specified flags and simplification ratio.

Declaration

public static void GenerateSimMesh(ref Mesh originalMesh, ref Mesh simMesh, bool simplifyMesh = false, bool convexifyMesh = false, bool weldColocatedVertices = true, float simplificationRatio = 1)

Parameters

Type	Name	Description
Mesh	originalMesh	Source mesh to process.
Mesh	simMesh	Output simulation mesh.
bool	simplifyMesh	Should the mesh be simplified to reduce triangle count.
bool	convexifyMesh	Should the mesh be made convex.
bool	weldColocatedVertices	Should vertices at the same position be merged.
float	simplificationRatio	Target triangle count as ratio of original (0-1).

SignedVolumeOfTriangle(Vector3, Vector3, Vector3)

Calculates the signed volume of a triangle with respect to the origin. Used for mesh volume calculations.

Declaration

public static float SignedVolumeOfTriangle(Vector3 p1, Vector3 p2, Vector3 p3)

Parameters

Type	Name	Description
Vector3	p1	First vertex.
Vector3	p2	Second vertex.
Vector3	p3	Third vertex.

Returns

Type	Description
float	Signed volume of the triangle.

VolumeOfMesh(Mesh, Transform)

Calculates the volume of a mesh in world space. Takes into account the transform's scale, position and rotation.

Declaration

public static float VolumeOfMesh(Mesh mesh, Transform transform)

Parameters

Type	Name	Description
Mesh	mesh	Mesh to calculate volume for.
Transform	transform	Transform containing scale information.

Returns

Type	Description
float	Volume of the mesh in cubic meters.

WeldVertices(ref Mesh, float)

Merges vertices that are closer than the specified distance threshold. Improves performance by reducing vertex count and removing duplicates.

Declaration

public static void WeldVertices(ref Mesh aMesh, float aMaxDelta = 0.001)

Parameters

Type	Name	Description
Mesh	aMesh	Mesh to process.
float	aMaxDelta	Maximum distance between vertices to be considered duplicates.
