[scilab-Users] Plot3d1 with spheres in diffrent colors, how?

[Constellation Athome]

Hi Calixte,

thank you for the code snippet. It works well, but may I ask another
question?
I want to "turn" the plot with alpha and theta angle. I want to do that to
take screencapters from each position for an animation.  but when I do that
with a simple for and try to plot them, the colors are not there or every
sphere has the same color.
could you please tell me how to achieve that?

best regards,

Andreas
