Public Functions Documentation

function AffineBodyConstitution

uipc::constitution::AffineBodyConstitution::AffineBodyConstitution (
    const Json & config=default_config()
) noexcept

---

function apply_to [1/2]

void uipc::constitution::AffineBodyConstitution::apply_to (
    geometry::SimplicialComplex & sc,
    Float kappa,
    Float mass_density=1e3
) const

---

function apply_to [2/2]

Apply ABD constitution with explicit mass matrix and volume override.

void uipc::constitution::AffineBodyConstitution::apply_to (
    geometry::SimplicialComplex & sc,
    Float kappa,
    const Matrix12x12 & mass,
    Float volume
) const

The 12x12 mass matrix is decomposed into (m, m_x_bar, m_x_bar_x_bar) and stored as meta attributes so the backend uses them directly instead of computing from mesh geometry.

function create_material

AffineBodyMaterial uipc::constitution::AffineBodyConstitution::create_material (
    Float kappa
) noexcept const

---

Public Static Functions Documentation

function default_config

static Json uipc::constitution::AffineBodyConstitution::default_config () noexcept

Protected Functions Documentation

function get_uid

virtual U64 uipc::constitution::AffineBodyConstitution::get_uid () noexcept override const

Implements uipc::constitution::IConstitution::get_uid

---

function setup_abd_attributes

Common ABD attribute setup without volume computation.

void uipc::constitution::AffineBodyConstitution::setup_abd_attributes (
    geometry::SimplicialComplex & sc,
    Float kappa,
    Float mass_density,
    Float volume
) const

Sets constitution_uid, transforms, dof_offset, dof_count, is_fixed, is_dynamic, external_kinetic, velocity, self_collision, kappa, volume, and mass_density attributes.

Subclasses (AffineBodyShell, AffineBodyRod) call this with their own pre-computed volume instead of compute_mesh_volume().
