[Gate-users] Projection

[Barbara Genocchi]

Dear all,


does anyone knows why even if I move the source the projection (whichever direction XY, YZ, XZ) is always a white dot in the middle of the picture? You can find attached the two images and following you can see my code.


I hope someone of you could help me!


Regard,

Barbara
