struct t8_cmesh_mesh_deformation

Struct for mesh deformation.

Public Functions

inline t8_cmesh_mesh_deformation(t8_cmesh_t cmesh)

Constructor.

inline ~t8_cmesh_mesh_deformation()

Destructor.

std::unordered_map<t8_gloidx_t, t8_3D_vec> calculate_displacement_surface_vertices(const t8_cad_handle *cad)

Computes the displacements of the surface vertices.

Parameters:

cad – [in] A pointer to the CAD-based geometry object.

Returns:

Map from global vertex ID to 3D displacement vector

void apply_vertex_displacements(const std::unordered_map<t8_gloidx_t, t8_3D_vec> &displacements, std::shared_ptr<t8_cad_handle> cad)

Apply vertex displacements to a committed cmesh.

Iterates over the provided map of global vertex IDs to 3D displacement vectors, updating the coordinates in each tree where the vertex appears.

Parameters:

  • displacements – [in] Map from global vertex ID to 3D displacement vector [dx, dy, dz].

  • cad – [in] The shared pointer to the CAD geometry to update.
