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