I might be missing the obvious here. Still, I understand an affine transformation is a transformation that preserves collinearity and ratio of lengths, and I'm struggling to understand what it means for B-Splines to be affine invariant though. I know that when an affine transformation is applied to a B-Spline, we only need to apply the transformation to the control points to find the new curve. Is this all there is to say?
Thank you for any help
