MegaPOV has a patch for mechanical simulations, in case this
is of interest to you.

Getting the light intensity at a point would not seem the
best choice for that even if possible. At least I don't think
heliotropic plants look for bright surfaces, they probably
target the light sources directly and you know where
those are in the scene anyway.
Actually I think the term heliotropic is reservered for plants
which actually turn towards the light actively, as opposed
to just growing towards the light.
