Struct TriMeshView 

pub struct TriMeshView<'a> {
    pub raw: &'a TriMesh,
}

Read-only access to the properties of a triangle mesh.

Fields

raw: &'a TriMesh

The raw shape from Rapier.

Implementations

impl<'a> TriMeshView<'a>

pub fn num_triangles(&self) -> usize

The number of triangles forming this mesh.

pub fn triangles( &self, ) -> impl ExactSizeIterator<Item = (Vect, Vect, Vect)> + '_

An iterator through all the triangles of this mesh.

pub fn triangle(&self, i: u32) -> (Vect, Vect, Vect)

Get the i-th triangle of this mesh.

pub fn vertices(&self) -> impl ExactSizeIterator<Item = Vect> + '_

The vertex buffer of this mesh.

pub fn indices(&self) -> &[[u32; 3]]

The index buffer of this mesh.

pub fn flat_indices(&self) -> &[u32]

A flat view of the index buffer of this mesh.

pub fn flags(&self) -> TriMeshFlags

The flags controlling the optional data associated to this mesh.

pub fn triangle_normal(&self, i: u32) -> Option<Vect>

The outward normal of the i-th triangle, or None if it is degenerate.

pub fn is_backface(&self, feature: FeatureId) -> bool

Does the given feature (as returned by a ray-cast or point projection on one of the triangles) identify the back face of that triangle?

pub fn topology(&self) -> Option<&TriMeshTopology>

The half-edge topology of this mesh, if it was computed.

This requires the TriMeshFlags::HALF_EDGE_TOPOLOGY flag.

pub fn connected_components(&self) -> Option<&TriMeshConnectedComponents>

The connected components of this mesh, if they were computed.

This requires the TriMeshFlags::CONNECTED_COMPONENTS flag.

pub fn num_connected_components(&self) -> Option<usize>

The number of connected components of this mesh, if they were computed.

pub fn connected_component_colliders( &self, flags: TriMeshFlags, ) -> Option<Vec<Result<Collider, TriMeshBuilderError>>>

Builds one triangle mesh collider per connected component of this mesh, each built with the given flags.

Returns None if the connected components were not computed.

pub fn pseudo_normals(&self) -> Option<&TriMeshPseudoNormals>

The vertex and edge pseudo-normals of this mesh, if they were computed.

They are computed with the TriMeshFlags::ORIENTED or TriMeshFlags::FIX_INTERNAL_EDGES flags.
