Thanks for posting what you had to do and persevering! I had only used OSX where things just automatically worked without any additional steps, so I didn't know the issues, evidently. By the way, try this: sage: from sage.plot.plot3d.shapes import * sage: from sage.plot.plot3d.plot3d import plot3d sage: S = Sphere(.5, color='yellow') sage: S += Cone(.5, .5, color='red').translate(0,0,.3) sage: S += Sphere(.1, color='white').translate(.45,-.1,.15) + Sphere(.05, color='black').translate(.51,-.1,.17) sage: S += Sphere(.1, color='white').translate(.45, .1,.15) + Sphere(.05, color='black').translate(.51, .1,.17) sage: S += Sphere(.1, color='yellow').translate(.5, 0, -.2) sage: def f(x,y): return math.exp(x/5)*math.cos(y) sage: P = plot3d(f,(-5,5),(-5,5), ['red','yellow'], max_depth=10) sage: cape_man = P.scale(.2)+S.translate(1,0,0) sage: foo = Sphere(.5, color='yellow') sage: for i in range(10): foo += cape_man.translate(randint(0,5),randint(0,5),randint(0,5)) sage: foo.show() You'll get a whole fleet of caped men. At least on my machine once they appear maximize the window -- then rotate around -- it feels very snappy. Here is a nice test of rotating lots of spheres all at once: sage: from sage.plot.plot3d.shapes import * sage: from sage.plot.plot3d.plot3d import plot3d sage: S = Sphere(.5, color='yellow') sage: for i in range(200): S += Sphere(.45, color='red').translate(randint(-5,5),randint(-5,5),randint(-5,5)) sage: S.show() Again, on my machine at least it feels very fast. It's this sort of robustness and speed even for complicated scenes that I think is critical to success.
