lucidshape曲线定义Note the curve's sharp turn at (x,y)=(1,0.5) which is enabled by a double knot multiplicity at t=3 (while the curve is smooth at the rest of the knots). To achieve another sharp turn at (x,y)=(1,-0.5), we would have to increase the multiplicity of knot t=2 by one (and thus reduce the smoothness constraints).
