Accessing the values within a formula for the Formula Deformer


Hi all,

There are a few old (and a few very old) threads around this topic but most of them seem incomplete and have missing links/downloads.

I’m looking for way to access (and animate) the wave length and wave speed written in the default formula in a Formula Deformer, which are expressed as ‘u’ and ‘t’ respectively.

There are some python scripts and talk of user data floating around the web but none of it seems complete, does anyone know of a good learning resource for this? I need to be able to properly art-direct some sine-wave ripples in a surface.

Many thanks in advance for any help offered!
