turbo_moc.geometry.spline_tool module

turbo_moc.geometry.spline_tool – B-spline fitting/evaluation used by turbo_moc.geometry.blade to reduce a dense blade-profile polyline to a small set of control points (for CAD/optimization use) and reconstruct a smooth curve from them.

Originally ported from opt_framework/test_2/01_geometry_parametrization/utils/ spline_gen.py (BSplineTool). Basis assembly/evaluation use SciPy’s compiled routines; parameterization, normal-equation fitting, and endpoint conventions are retained.

Methods

backward(data_points, num_cp)	Generates control points from data points using Least Squares.
backward_fixed(data_points, num_cp)
forward(control_points, knots[, num_points])	Generates the curve from control points (Forward Method).
reparameterize_equidistant(data_points[, ...])	Re-samples data points so they are physically equidistant along the arc length.

backward(data_points, num_cp)

Generates control points from data points using Least Squares. Uses a Uniform Knot Sequence for equispaced control variables.

backward_fixed(data_points, num_cp)

forward(control_points, knots, num_points=500)

Generates the curve from control points (Forward Method).

reparameterize_equidistant(data_points, num_points=500)

Re-samples data points so they are physically equidistant along the arc length. Prevents clustered data from distorting CP distribution.
