Post search, I have not been able to find a solution to my project. Several posts were tangential to my problem.
The goal: Create a logarithmic spiral along a truncated cone surface (identical points = matching UV).
The reason: Need a stair with a steady gradient (rise/tread) along a truncated cone
What I do not want (but have): A spiral around a truncated cone. Each revolution has the same increase in height (Z) but different lengths (see screenshot). I want the opposite; a steady increase in height resulting in varying heights for each revolution due to the longer spiral curve.
The ideal solution would allow control over riser and tread but I think I can work that out once the spiral is figured out.
I look forward to learning from you. Thanks for reading this far.
