java - Drawing a curved shape that bends along a curved trajectory -

so, wish able draw, example, raindrop in slow-motion falls top of screen. it's trajectory changes straight down , instead follows quadratic curve towards left. tricky bit raindrop's shape bends in direction follow curve. image below demonstrates intended effect want achieve programmatically.

if want specific coordinates, let's path begins @ 0,0 travels 0,50, curves -15,100 control point @ 0,70. typical raindrop shape can achieved through 2 mirrored bezier curves demonstrated in image below.

i know there's way derive points along curve, means can derive start , end points of raindrop along it's curved path, don't know control points. if derive angle of end-point's trajectory, might find answer rotating control points relative that; i'm not sure enough. next step in problem happens when raindrop passes through several small curves in trajectory. can't summarised single bezier curve per side can they? (not java kind @ least, unless i'm missing allow 2 control points). can work out given enough time, use coming theoretical/algorithmic solution this.

is there out there tackles this?
