Struct gut::mesh::uniform_poly_mesh::QuadMeshExt

pub struct QuadMeshExt<T: Real> {
    pub base_mesh: QuadMesh<T>,
    pub face_indices: Vec<usize>,
    pub face_offsets: Vec<usize>,
}

Fields

base_mesh: QuadMesh<T>

Vertex positions.

face_indices: Vec<usize>

Lists of face indices for each vertex. Since each vertex can have a variable number of face neighbours, the face_offsets field keeps track of where each subarray of indices begins.

face_offsets: Vec<usize>

Offsets into the face_indices array, one for each vertex. The last offset is always equal to the size of face_indices for convenience.
