I need a (simplest) function that interpolates values in range from predefined point $A$ to $B$ with rules:
- it must be smooth curve
- direction near $B$ must be the same as predefined $D$ vector
I have a variant to build circle arc but is too complex. Maybe some sort of splines, but I don't know how to represent it with my $A$, $B$ points and $D$ vector.
