2 ways to draw a spectra set with plot 3D

Reading the article "Fifty ways to draw a volcano using package plot3D",

I wanted to test it with spectra (in this case treated with SNV). The result looks nice, but I have to practice more with it.

It seems that there are nice applications to use these plots in Chemometrics for tutorials, so more ideas are coming how to use them.

persp3D(z = X2.val_snv, facets = FALSE, col = "darkblue")

> persp3D(z = X2.val_snv)
