Comment (by kcrisman):
Okay, jmol does indeed 'work' (though without the colormap) in command
line and notebook, though the Tachyon pic is the static piece in the
notebook, I think.
{{{
sage: from sage.plot.plot3d.parametric_surface import ParametricSurface
sage: cm = colormaps.autumn
sage: def c(x,y): return sin(x*y)**2
sage: def g(x,y): return x, y, x**2 + y**2
sage: P1 = ParametricSurface(g, (srange(-10,10,0.1),
srange(-5,5.0,0.1)),color=(c,cm))
sage: P1.show()
}}}
However,
{{{
sage: sage: var('x,y,z')
(x, y, z)
sage: t = (sin(2*y+3*z)**2).function(x,y,z)
sage: cm = colormaps.gist_rainbow
sage: sage: implicit_plot3d(x^2+y^2+z^2==4, (x, -3, 3), (y, -3,3), (z,
-3,3), color=(t,cm))
}}}
doesn't. Given that this is supposed to work with Tachyon, it should
presumably at least fail gracefully for Jmol. Is this maybe a difference
between parametric and implicit plotting?
