Hi,

Can anyone explain Arc-Length parameterization to me? Or possibly supply a shove in the right direction on finding a point on a curve using arc length parameterization? I am trying to have an object traverse a curve at constant speed.

Thanks much!

Dave Eberly has a good paper on the topic in the documentation section of his site, geometrictools.com. Don't have time to link to it at the moment, but it shouldn't be too hard to find.

The paper explains the concept behind arc-length reparameterization and (IIRC) provides some tips on implementation.
