Hello, i need make a parabolic mirror surface but i don’t know how. I make a flat mirrors with go.Surface and work fine, but for curved surface maybe not work fine (?).

The mirror have axis rotation, therefore i use a parametric equation:

phi=0*np.pi/180

##phi=0 → parable open to right

##phi=90 → parable open to up

malla=[ ]

perfil=[ ]

V=[0,0]

foco=4

dt=0.001

t=np.arange(-(p[1]/4) , (p[1]/4)+dt , dt)

##p[1]=0.5 in this case

y=(V[0] + (foco/2)*np.cos(phi)*t**2 + foco*np.sin(phi)*t)

z=(V[1] + (foco/2)*np.sin(phi)*t**2 - foco*np.cos(phi)*t)

x=np.arange(0,4,dt)

xx , yy = np.meshgrid( x , y )

malla.append([xx,yy])

perfil.append(z)

surf=go.Surface(x=malla[0][0][0],

y=malla[0][1],

z=perfil[0])

fig=go.Figure(data)

po.plot(fig)

I hope you can help me, **any idea or solution is welcome**!!
