I have a periodic rough 2D surface in an array V(x,y) which I want to map into a 3D rough surface around a cylinder radius R. (Like pictured)
My coordinate transforms are rusty and I cant work out how to do this mapping. Does somebody know how to acheive this for my generic non-analytic surface?
If possible please avoid solutions using Matlab's "cylinder" function, as I want to port this to another language.
Thanks in advance :)
