Comment(by wcauchois):
Has anyone else noticed that some of the plots, when rendered using the
Jmol backend, look very bumpy? The Tachyon renderings of the same plots,
however, are fine. William thought the surface normals might be incorrect,
but actually, if you zoom in on the model, you can perceive jagged edges
in some cases. Is this a bug or a feature? Does anyone know what the
problem might be?
To see what I mean, try this code:
{{{
var('x,y,z')
P = implicit_plot3d((x^2 + y^2 - 1) * ( x^2 + z^2 - 1) - 1, (x, -3, 3),
(y, -3, 3), (z, -3, 3))
P.show(viewer='jmol')
# P.show(viewer='tachyon') # uncomment this
}}}
