constraints.solve.solve_constraints

constraints.solve.solve_constraints(sdf, *, tol=1e-06, max_steps=256)

Solve geometric constraints attached to a scene’s free parameters.

Extracts free parameters from the SDF tree, discovers all constraints registered on them, checks that the system is exactly constrained, then runs Levenberg-Marquardt (via optimistix) to find parameter values that satisfy all constraints.

Parameters

Name	Type	Description	Default
sdf	Fluent	The SDF tree whose free parameters should be solved.	required
tol	float	Convergence tolerance (used as both rtol and atol).	1e-06
max_steps	int	Maximum solver iterations.	256

Returns

Name	Type	Description
	dict[str, Any]	A free_params dict (same format as extract_parameters) with solved
	dict[str, Any]	parameter values — ready to pass to functionalize.

Raises

Name	Type	Description
	ValueError	If the scene is under- or over-constrained.
	RuntimeError	If the solver does not converge.

Example

solved_params = solve_constraints(scene)
sdf_fn = functionalize(scene)(solved_params, fixed_params)
