Expand description

A triangle (surface) mesh in 3D

Fields§

§vertices: Vec<Vector3<R>>

Coordinates of all vertices of the mesh

§triangles: Vec<[usize; 3]>

The triangles of the mesh identified by their vertex indices

Implementations§

source §

impl<R: Real> TriMesh3d<R>

source

pub fn triangle_cells(&self) -> &[TriangleCell]

Returns a slice of all triangles of the mesh as TriangleCells

source

pub fn clear(&mut self)

Clears the vertex and triangle storage, preserves allocated memory

source

pub fn append(&mut self, other: &mut TriMesh3d<R>)

Appends the other mesh to this mesh

This operation appends the content of the other mesh’s vertex and triangle storage tho this mesh. The vertex indices of the appended triangles are adjusted accordingly. The other mesh will be empty after this operation.

source

pub fn vertex_normal_directions_inplace( &self, normal_directions: &mut [Vector3<R>] )

Computes the mesh’s vertex normal directions inplace using an area weighted average of the adjacent triangle faces

Note that this function only computes the normal directions, these vectors are not normalized! See Self::vertex_normals_inplace if actual normal vectors are needed.

The method will panic if the length of the output slice is different from the number of vertices of the mesh.

The method does not make any assumptions about the values in the output slice.

source

pub fn vertex_normal_directions(&self) -> Vec<Vector3<R>>

Computes the mesh’s vertex normal directions using an area weighted average of the adjacent triangle faces

Note that this function only computes the normal directions, these vectors are not normalized! See Self::vertex_normals if actual normal vectors are needed.

source

pub fn vertex_normals_inplace(&self, normals: &mut [Unit<Vector3<R>>])

Computes the mesh’s vertex normals inplace using an area weighted average of the adjacent triangle faces

The method will panic if the length of the output slice is different from the number of vertices of the mesh.

The method does not make any assumptions about the values in the output slice.

source

pub fn vertex_normals(&self) -> Vec<Unit<Vector3<R>>>

Computes the mesh’s vertex normals using an area weighted average of the adjacent triangle faces

source

pub fn par_vertex_normals_inplace(&self, normals: &mut [Unit<Vector3<R>>])

Computes the mesh’s vertex normals inplace using an area weighted average of the adjacent triangle faces (parallelized version)

The method will panic if the length of the output slice is different from the number of vertices of the mesh.

The method does not make any assumptions about the values in the output slice.

source

pub fn par_vertex_normals(&self) -> Vec<Unit<Vector3<R>>>

Computes the mesh’s vertex normals using an area weighted average of the adjacent triangle faces (parallelized version)

source

pub fn compute_edge_information(&self) -> MeshEdgeInformation

Computes a helper struct with information about all edges in the mesh (i.e. number of incident triangles etc.)

source

pub fn find_non_manifold_vertices(&self) -> Vec<usize>

Returns all non-manifold vertices of this mesh

A non-manifold vertex is generated by pinching two surface sheets together at that vertex such that the vertex is incident to more than one fan of triangles.

Note: This function assumes that all edges in the mesh are manifold edges! If there are non- manifold edges, it is possible to connect two triangle fans using a third fan which is not detected by this function.
