Excellent work. Thanks a lot.

I am getting the below error while trying to run your _demo program

??? Error using ==> polarplot3d at 153
Error parsing varargin list
??? Error using ==> lower
Cell elements must be character arrays.

Can you let me know what needs to be fixed to sucessfully run the program?

Hey, I had some problems plotting earth in 3D. The interpolation does not interpolate between 0 and 2pi. Therefore I get always a stripe at the 0 degree meridean. can some one fix that problem ?

Really great! Your job makes life easier.
while Line 317, 318 should be like this

step = (c-1)/(r-1); %1:r change to 1:c
[X1,Y1] = meshgrid(1:c,1:step:c); %start from 1 not 0

to get correct interpolation result of more angle columns.

Otherwise I get asymmetrical interpolation on both sides of 0/360.

Phenomenal Program. You guys absolutly rock.
@Teemu Teekkari
you can use polar3d to output the x,y,z values. THen use surf to make the plot. In suck you can turn off the grid lines. I think that should do what your trying to do.
