Plotting functions with Jmol

The sinc function (a.k.a. “sombrero” [Mexican hat])

sinc(r) = sin(r) / r

Plot wire mesh using data points read from file, javascript and "draw" command:

Calculate & plot surface using javascript and "isosurface functionXY" command with resolution=:
or surface from disk (much faster)
Surface features (combine at will):

Show data points (they are small, you may need to zoom in)

Background color:

The Fourier integral kernel, exponentially damped

exp(-t) · exp(-2 π i k t)
= exp(-t) · [ cos(2 π k t) + i sin(2 π k t) ]

or

x = exp(-t) · sin(2 π k t)
y = exp(-t) · cos(2 π k t)
z = t

Plot line (with k=1) using data points read from file, javascript and "draw" command: Show data points
