- bspleval(x, knots, coeffs, order, periodic=False)#
Evaluate a B-spline at a set of points. The designability can be kept when coeffs contains Dv.
- Parameters:
x (list or ndarray) – The set of points at which to evaluate the spline. Can be given by scipy.
knots (list or ndarray) – The set of knots used to define the spline. Can be given by scipy.
coeffs (list of ndarray) – The set of spline coefficients. Can be given by scipy.
order (int) – The order of the spline.
- Returns:
- y (ndarray)
The value of the spline at each point in x.
More details here.
- createBspline(xCoords, yCoords, zCoords, nknots, axis='xyz', periodic=False)#
Return the knots, coef and order of x/y/z spline. Compute the deviation from the sampling points and return it as well. Return None if a specific direction is not designable.
- curveReadyForDesignable(curve)#
Check if the given Curve is ready to be made designable.
This is a method of the
Curve
class.
- dcurveReadyForDesignable(dcurve, rm=None)#
Check if the given DeformableCurve is ready to be made Designable.
This is a method of the
DeformableCurve
class.
- makeCurveDesignable(curve, nknots=0, axis='xyz', xbound=None, ybound=None, zbound=None, tol=0.001, periodic=False)#
Make the 3D Curve Designable. The number of Dvs is n*knots, where n is the number of designable axes. If curve.matrix is already designable, then a warning is raised.
This is a method of the
Curve
class.
- makeDeformableCurveDesignable(dcurve, nknots=0, axis='xyz', rm=None, xbound=None, ybound=None, zbound=None, tol=0.001, periodic=False)#
Make the DeformableCurve Designable. The number of Dvs is n*knots, where n is the number of designable axes. If dcurve.markers are already designable, then a warning is raised.
This is a method of the
DeformableCurve
class.
