`x`	Object of type `soo_function` to plot.
`lower`	Lower bounds of x1 and x2.
`upper`	Upper bounds of x1 and x2.
`n`	Number of locations at which to sample the function.
`main`	Main title of plot.
`xlab`	Label of x (x1) axes.
`ylab`	Label of y (x2) axes.
`log`	If `TRUE`, the z axes is plotted on log scale.
`rank`	If `TRUE`, instead of the y values, their ranks are drawn.
`...`	Passed to `persp3d.default`. par(mfrow=c(1, 3)) fn <- generate_sphere_function(2) plot3d(fn) plot3d(fn, log=TRUE) plot3d(fn, rank=TRUE)
