Gnuplot_ellipsoid.svg (45 kB, định dạng MIME: image/svg+xml)


An ellipsoid drawn with gnuplot. This picture has been done with the direct output of the SVG driver. Note that some of the elliptical cross-sections are bumpy; this indicates that they are spline curves that only approximate ellipses.

To reproduce, use the commands:

set parametric
splot cos(u)*cos(v),2*sin(u)*cos(v),3*sin(v)
set contour base
set grid xtics ytics ztics
unset key
set term svg
set output "Gnuplot_ellipsoid.svg"
replot
