comment Shaded 3D ellipsoid with pgfplot
To the best of my knowledge, PGFplots does not do "realistic" (light-based) shading. Have you considered Asymptote?

comment what is the best way to export 3D plots in Latex
It looks like the surfaces in the tikz plot are being drawn in the wrong order--starting with the surfaces closest to the viewpoint, so that the farther surfaces are drawn on top of them.

comment Fill a region between two coplanar paths in asymptote
An alternative is to use the surface(path[]) routine, which will construct the surface in the xy-plane; then, use transformations to put the surface in the desired position.

comment asymptote multiple graphics in single file
Please clarify what is meant by an "indexed set of figures". Are these files with names like foo-1.eps, foo-2.eps, etc.?

comment Asymptote: How can I mix two colours
interp(RoyalBlue, white, 0.75), where interp stands for "interpolate", will give you 75% of the way from RoyalBlue to white.

comment Asymptote: Arrow3 only has 3D arrow head
@MrZ: You can't directly apply a material to a path3. To specify a full-blown material (as opposed to just a color and lighting), you need to get the actual surface (the arrowhead and the tube). I recommend you try to find a satisfactory color/lighting combination before resorting to this.

comment Transparent background in Asymptote animation
Your experience seems to be mistaken: 3d outputs always have opaque background in any file format unless settings.render = 0;.

comment Change font in Asymptote
If you are putting this as a line in the asy file, I think the line you want is usepackage("mathpazo");. The line texpreamble("\usepackage{mathpazo}"); will also work.

comment Wrong subpath with end intersection points
The problem is the way subpath works: if you place the greater time first, then it implicitly reverses the order (although it also switches the path orientation). In your case, you can make it do the right thing by changing the last line to sp = sp^^subpath(abc,arr[5][0], length(abc) + arr[0][0]);.

comment Compute and draw a convex hull
Plotting the original points and the convex hull in one line was suggested only because it's the sort of thing that happens in TikZ syntax; it's not a requirement for a good answer.
