Comment (by chapoton):
The `'canvas3d'` viewer (using `json` output with colors defined here and
a patched `sagenb`) results look good, but there seems to be a little
problem in the notebook. Here is one example
{{{
from sage.plot.plot3d.parametric_surface import ParametricSurface
cm = colormaps.autumn
def c(x,y): return sin(x*y)**2
def g(x,y): return x, y, x**2 + y**2
P1 = ParametricSurface(g, (srange(-10,10,0.1), srange(-5,5.0,0.1)),(c,cm))
}}}
When one defines several parametric surfaces, say P1 and P2. Try
P1.show(viewer='canvas3d') inside one cell. Then change '''this cell''' to
P2.show(viewer='canvas3d'). It will still show P1 and will never change,
whatever you do to P1. No such problem inside a new cell. Seems to be some
caching problem.
