b0 b1 b2 b3 b4 bn
Spline of polynomial-base b(1,2,3,4) generated by CURVE2 (degree 2), CURVE3 (degree 3) scripts
- corresponding to a standard knot vector
- Execution not automated.
- B(0,n) repeated knots (2 times) at start and end - see Parametric Curves.
pre defined steps=100, set steps=nn - in command line for an other resolution ...
spline plot density (step points with polyline)
slider a0 knot0...2, a1 knot+1 , a2 knot+2 , a3 knot+3 , a4 knotn+m-1...n+m+1
for degree 2, 3 - on/off []
Extend P with additional points/knots.
I don't think my js.code is very elegant or fast - i stay very close to the mathematical notation as i understand it to keep the code readable and I hope comprehensible.
apart from the knot vector length check red/green, no input checks are carried out.
