Plotting Interlocking Tori with Gnuplot

#1

Below is an example of how to generate 3D graphs with Gnuplot.

And the following is the code that implements the plot.

Code: [Select all] [Expand/Collapse]

gnuplot> set terminal png truecolor nocrop enhanced size 450,320 font "arial,8" 
Terminal type set to 'pngcairo'
Options are ' background "#ffffff" enhanced font "arial,8" fontscale 1.0 size 450, 320 '
gnuplot> set output 'hidden2.2.png'
gnuplot> unset border
gnuplot> set dummy u, v
gnuplot> set format cb "%.1f"
gnuplot> unset key
gnuplot> set parametric
 
    dummy variable is t for curves, u/v for surfaces
gnuplot> set view 60, 30, 1.5, 0.9
gnuplot> set isosamples 50, 20
gnuplot> set size ratio 0 0.55,0.9
gnuplot> set origin 0.4,0
gnuplot> unset xtics
gnuplot> unset ytics
gnuplot> unset ztics
gnuplot> set title "3D surface sorting posted at http://forums.tssfl.com" 
gnuplot> set urange [ -3.14159 : 3.14159 ] noreverse nowriteback
gnuplot> set vrange [ -3.14159 : 3.14159 ] noreverse nowriteback
gnuplot> set pm3d depthorder
gnuplot> set colorbox user
gnuplot> set colorbox vertical origin screen 0.9, 0.15, 0 size screen 0.02, 0.5, 0 front bdefault
gnuplot> g(x,y) = sin(-sqrt((x+5)**2+(y-7)**2)*0.5)
