Hi,
I'm working on Matlab R2008a (without toolbox…)
i'd like to know how to change the color of points located at the surface of a sphere given that they are on the frontside or the backside of this sphere.
Usually, i've got several points which cover all the surface of the sphere. With "facealpha" i can see the points located on the backside of the sphere, but with the same color. So the distinction of points is difficult.
The better for me should be to have the "front" points in red and the "backside" points in bleu, and this for any arbitrary initial orientation of the sphere
Is that possible ? Thanks for your attention
