Just trying out how to create a 'corkscrew' type spiral that does not decrease in size. I found a tut on creating spirals by Ewan Smith, but not sure how to adjust the expression- I have tried changing certain values, but being honest my maths is not up to it!
(Spiral shape -applied to light controlling particular emitter position)
//z=0 // no depth
z=time*time // with depth
You can make a corkscrew pretty quickly by parenting your light to a 3D null, offsetting the light from the null's center, then animating the null's rotation and position.
If you want the corkscrew to tighten, you can also animate the position or anchor of the light (which because of the parenting, will be relative to the null).
