Motion on more complex curves?
Apr 7th, 2006, 8:03am  
Hey guys,

Im not really an expert in either programming or mathematics, but I have a problem Id like to chip away at. Essentially, I would like to be able to create custom curves (bezier perhaps?) and have ellipses follow these curves.

The example ive been looking at is from the learning section of the website: http://www.processing.org/learning/examples/movingoncurves.html

This is nice, but I what I really want to do is to draw my own curves and have objects follow them rather than having them follow the path of a simple sine curve.

Also, im curious what kind of stress this would put on the framerate. Ideally I want a lot of objects on the screen following the curves (in the area of 200+).

Anyways, my question is pretty broad ... but If someone could give me a few tips or point me in the right direction it would be appreciated,

Thanks

You might want to take a look at craig reynold's steering algo:

Also, in processing it is very easy to obtain x/y data from a curve, simply by using built-in functions such as bezierPoint or curvePoint.
