Here I fill the space below the function z = x^2+y^2 to get a solid object. I did it by: Plotting the curves at the…

Here you can sdee Tufte style axes in 3D. The axis affect is achieved by shifting axes, ticks and labels. The command \pgfplotspointouternormalvectorofticklabelaxis{x} is a…

For drawing a spiral cone, we need to find an appropriate parametrization. This code was written by Gonzalo Medina on TeX.SE. \documentclass[border=5pt]{standalone} \usepackage{pgfplots} \pgfplotsset{width=7cm,compat=1.8} \usetikzlibrary{decorations.markings}…

We would like to make an image to illustrate the construction of a spiral capacitor. These are made of spiral coiled films. Itâ€™s like a…
