How do you construct a hemisphere (like a half of a ball) in the 3D mode? A simple answer would be for the best but I'm open to any ideas.
Hi, you can use the command : surface. An example :
Surface(cos(a) cos(b), sin(a) cos(b), sin(b), a,0,2 pi, b,0,pi/2)
A free point
f: Line(A, A + (1, 0))
c = Curve(A + (3; θ), θ, 0, π)
a = Surface(c, 180°, f)
so can you move A (Try also A=(1,1,1) y vector (1,0,0) for f )
Hi! Problem solved, both of the first answers worked, so I didn't have to try the third one. Thank you so much!
