Detailed Description

Chain operator that applies Tendency field deformation to the vertex data of individual MeshNetwork slots.

Holds one FieldOperator per bound slot, keyed by slot index. bind() creates or replaces the per-slot FieldOperator and initialises it from the slot's current MeshVertex array so the reference frame is always the geometry as it existed at bind time.

process_slot() runs the slot's FieldOperator::process(dt) then writes the resulting MeshVertex array back via slot.node->set_mesh_vertices(). That call sets m_vertex_data_dirty on the MeshWriterNode, which any_slot_dirty() in MeshNetworkProcessor already checks.

Slots without a bound FieldOperator are skipped entirely.

This operator belongs in the OperatorChain, not as the primary operator. MeshTransformOperator runs first (as primary) to propagate world transforms; MeshFieldOperator runs after to deform vertex positions in local space.

Usage:

auto field_op = std::make_shared<MeshFieldOperator>();
net->get_operator_chain()->emplace<MeshFieldOperator>();
 
// Retrieve the typed pointer from the chain or hold it before emplacing.
field_op->bind(torso_idx, FieldTarget::POSITION,
    Kinesis::make_radial_pull(glm::vec3(0), 4.0F));
