functionalize.functionalize_scene

functionalize.functionalize_scene(geometry)

Compile a geometry SDF tree to pure (sdf, material_fn) closures.

Returns a curried function::

scene_fn = functionalize_scene(geometry)
sdf, material_fn = scene_fn(free_params, fixed_params)
distance = sdf(point)
mat_dict = material_fn(point)

Both sdf and material_fn are pure JAX functions. This helper is for geometry and material evaluation; the forward image renderer deliberately has a separate, non-differentiable API.

The node counter matches extract_parameters exactly (same DFS order, same counter increments for every Fluent node), so path-keyed fixed params align correctly — including for a node reached twice, which is numbered twice there and built only once here.

Parameters

Name	Type	Description	Default
geometry		Root SDF node of the geometry tree.	required
