Public Functions Documentation

function AffineBodySphericalJoint

uipc::constitution::AffineBodySphericalJoint::AffineBodySphericalJoint (
    const Json & config=default_config()
) 

---

function apply_to [1/2]

Bind affine body instances to existing spherical joint geometry (single-instance mode).

void uipc::constitution::AffineBodySphericalJoint::apply_to (
    geometry::SimplicialComplex & sc,
    span< S< geometry::SimplicialComplexSlot > > l_geo_slots,
    span< S< geometry::SimplicialComplexSlot > > r_geo_slots,
    Float strength_ratio=Float{100}
) 

Pure binding: writes constitution UID, geometry IDs, instance IDs, and strength ratios on vertices. Does NOT build geometry.

---

function apply_to [2/2]

Bind affine body instances to existing spherical joint geometry (multi-instance mode).

void uipc::constitution::AffineBodySphericalJoint::apply_to (
    geometry::SimplicialComplex & sc,
    span< S< geometry::SimplicialComplexSlot > > l_geo_slots,
    span< IndexT > l_instance_ids,
    span< S< geometry::SimplicialComplexSlot > > r_geo_slots,
    span< IndexT > r_instance_ids,
    span< Float > strength_ratios
) 

Pure binding: writes constitution UID, geometry IDs, instance IDs, and strength ratios on vertices. Does NOT build geometry.

---

function create_geometry [1/2]

Create spherical joint geometry with world-space anchor positions.

geometry::SimplicialComplex uipc::constitution::AffineBodySphericalJoint::create_geometry (
    span< const Vector3 > positions,
    span< S< geometry::SimplicialComplexSlot > > l_geo_slots,
    span< IndexT > l_instance_ids,
    span< S< geometry::SimplicialComplexSlot > > r_geo_slots,
    span< IndexT > r_instance_ids,
    span< Float > strength_ratios
) 

Builds a vertex-based SimplicialComplex (1 vertex per joint). Writes vertices.position from positions. Does not write local position attributes.

---

function create_geometry [2/2]

Create spherical joint geometry with local-space anchor positions.

geometry::SimplicialComplex uipc::constitution::AffineBodySphericalJoint::create_geometry (
    span< const Vector3 > l_positions,
    span< const Vector3 > r_positions,
    span< S< geometry::SimplicialComplexSlot > > l_geo_slots,
    span< IndexT > l_instance_ids,
    span< S< geometry::SimplicialComplexSlot > > r_geo_slots,
    span< IndexT > r_instance_ids,
    span< Float > strength_ratios
) 

Builds a vertex-based SimplicialComplex (1 vertex per joint). Writes local position attributes (l_position, r_position) on vertices.
