I remember having spotted a link to a huge page with different equations to non linear interpolation curves, for example if you want to stop a car smoothly, etc.

Those can sometime be useful to emulate some real-world acceleration/velocity behaviors without the help of a physics engine, which can really simplify the code.

Any idea where this page is ? I can't manage to give google the right keywords...

EDIT: I just searched on my previous laptop bookmarks, and I found it: http://sol.gfxile.net/interpolation/

  • \$\begingroup\$ and sorry if the question gets closed, but I'll put the link in the wiki, that's like the #1 thing I think is important to progammers when thinking about maths. \$\endgroup\$ – jokoon Apr 18 '11 at 15:53

If you had searched for "easing formulas" it would've been the first result.

  • \$\begingroup\$ While this is useful, I think jokoon was looking for a specific page, and I do not think that this is the page he was looking for. \$\endgroup\$ – AttackingHobo Apr 19 '11 at 0:07
  • \$\begingroup\$ It's not that one but it has the equations, so that's good :) \$\endgroup\$ – jokoon Apr 19 '11 at 6:21

There is a realtime WYSIWYG interpolation editor: http://inloop.github.io/interpolator/
