releso.spline.NURBSDefinition

class releso.spline.NURBSDefinition(*, save_location: Path, logger_name: str | None = None, control_points: List[List[VariableLocation]] | None = None, space_dimensions: List[SplineSpaceDimension], weights: List[float | VariableLocation])

Bases: SplineDefinition

Definition of a NURBS spline.

Definition of the NURBS implementation of the ReLeSO Toolbox, in comparison to the B-Spline implementation only an additional weights vector is added.

__init__(**data: Any) → None

Constructor for the ReLeSO basemodel object.

get_logger()	Gets the currently defined environment logger.
get_number_of_points()	Returns the number of points in the Spline.
get_parameter_values()	Returns the current positions of all control points with weights as well.
get_shape()	Creates a NURBSSpline from the definition given by the json file.

classmethod convert_weights_into_variable_location(v: float | VariableLocation, values: Dict[str, Any]) → VariableLocation

Validator for variable weights.

Convert all float values in the weight vector into VariableLocations. So that these can also be used as actions.

Parameters:

• v (List[Union[float, VariableLocation]]) – Value to validate

• values (Dict[str, Any]) – Previously validated variables

Returns:

Filled weight vector.

Return type:

List[VariableLocation]

get_actions() → List[VariableLocation]

Extends the control point actions with the weight actions.

Returns:

List of possible actions for this NURBS spline.

Return type:

List[VariableLocation]

get_parameter_values() → List[List[float]]

Returns the current positions of all control points with weights as well.

Returns:

Positions of all control points.

Return type:

List[List[float]]

get_shape() → splinepy.NURBS

Creates a NURBSSpline from the definition given by the json file.

Returns:

NURBSSpline

Return type:

NURBS

get_weights() → List[float]

Returns the weights of the NURBS spline.

Returns:

List of weights.

Return type:

List[float]

reset() → None

Resets the spline to the original shape.

weights: List[float | VariableLocation]

weights for the NURBS Spline definition. Other parameters are part of the spline definition class. Can be fixed or changeable
