Formula for describing the flight path of a basket ball

Hi,

I would like to animate the movement of an image so it will follow a trajectory similar to a basket ball.

I need to translate the flight path into x/y co-ordinates using Javascript.

A symmetrical arc would be pretty easy to describe. But I want a path which is closer to a lob, like that of a basketball from the free throw point.

Could someone please point me to a formula or algorithm I could use for this ?

Regards,

Hello howtogetitright,

Have a look to the spline curve : http://local.wasp.uwa.edu.au/~pbourke/geometry/spline/index2.html

You can set three points (or more) and design a smooth curve passing on the three points.

Regards.
