Hi,
I'd like to use SUMA to create a visualization of vectors in a 3-D space. I'd like to visualize the projection of the vectors onto their intersection with the unit sphere. So I'd need a simple spherical surface of radius 1 to start with. Then I'd take my vectors and convert each to unit length (divide by its norm), and these would give me the coordinates on the surface of the unit sphere. I can deal with all the numbers in MatLab, but how to get it into SUMA for fancy visualization is where I'm lost. If anyone can sketch out a list of steps to get me from A to B, I'd be much obliged.

Thanks!
Aaron
