Hello
Yes you are right. I would like to picture the sphere as the earth
and then project the colors which rep the diff densities on that earth. I
guess I understand the concept but my data is in such a wierd form.
I have a vector X = [X1,X2,X3.....X4880] and Y = [y1,y2,..y4880] and
Z=[Z1,z2..z4880] and data=[d1,d2...d4880].. with the data in this format
how do i do the said transformation? Any help would be much appreciated.
