Here's a question about changing the viewpoint in a 3d plot: ----- Forwarded message from "Gagnon, Jacob A" ----- > Thanks. The server is up now. I have quick question about plot3d.

The relevant code is:
@interact
def _(mux=slider(-2,2,0.5,default=0,label='mux'),muy=slider(-2,2,
0.5,default=0, label='muy'),rho=slider(-0.75,.75, 0.25,default=0,
label='rho'),sx=slider(0.1,2, 0.1,default=1,
label='sx'),sy=slider(0.1,2, 0.1,default=1, label='sy')):
f(x,y) =
1/(2*pi*sx*sy*sqrt(1-rho^2))*exp(-1/(2*(1-rho^2))*((x-mux)^2/sx^2+(y-muy)^2/sy^2-2*rho*(x-mux)*(y-muy)/sx/sy))
g(x)=f(y=0)
h(y)=f(x=0)
p1=contour_plot(f(x,y),(x,-5,5),(y,-5,5),cmap='hsv')
p2=plot3d(f(x,y),(x,-5,5),(y,-5,5))
p3=plot(g(x),(x,-5,5))
p4=plot(h(y),(y,-5,5))
show(p1,figsize=3)
show(p2,figsize=3)
Do we have a way of specifying a viewpoint when doing a 3d plot?
