mypic = implicit_plot3d(x^2 + y^2 + z^2 == distance, (x, -10, 10), (y, -10, 10), (z, -10, 10), opacity = 0.5) + point3d(vector([0, 0, 0]), color = 'red', size = 10)
mypic.save('mypic.png', compress = false)
but the colors (in particular, the opacities) are washed out.
There is no problem right-clicking to save as png from the notebook, but I want to save a bunch of pngs.

I'd like to plot the solutions of the system
$$(X + Y )(X − Z^3)=0,$$
$$XY + Y^2=0.$$
in 3D, I mean, the set of points (X,Y,Z) in IR^3 that verify the system. I don't know how to do it. I was searching how to plot the intersection of both surfaces, but neither I could. ¿Could anyone tell me how to do it?
Thanks in advanceMinkowskiMon, 16 May 2016 18:03:59 +0200https://ask.sagemath.org/question/33418/
