The current version has been published as a book of about 350 pages by Cambridge University Press. By agreement with the Press, however, it will remain posted on this web site. Many improvements in the current version over previous ones are due to the (anonymous) referees of the Press, whom I wish to thank heartily. I also wish to thank Lauren Cowles, of the New York office of the Press, for much help with preparing the original version for publication. The paper edition appears also in Duotone red and black. For information on obtaining the paper edition, take a look at the Cambridge Press catalogue. https://www.math.ubc.ca/~cass/graphics/manual/jaeschke2018-11-01T08:59:35+01:00book geometry math postscript ps visualization <span itemprop="description">This manual has been available on this site since about 1996, with improvements taking place frequently.

(Gnuplot has no facilities for computing these values automatically.) The simplest way is to make a 2D histogram; the plot is divided in small 2D regions, and the z-values are proportional to the number of points inside these regions. The following Python script will make an histogram from a time series of two dihedral angles. http://pelican.rsvs.ulaval.ca/mediawiki/index.php/Making_density_maps_using_Gnuplotjaeschke2011-08-11T11:22:47+02:00density gnuplot histogram math plot programming <span itemprop="description">To make a density map from a 2D set of data, the first step is to compute values for the third dimension.

It's known as a 'fractal' - a type of shape that yields (sometimes elaborate) detail forever, no matter how far you 'zoom' into it (think of the trunk of a tree sprouting branches, which in turn split off into smaller branches, which themselves yield twigs etc.).
It's found by following a relatively simple math formula. But in the end, it's still only 2D and flat - there's no depth, shadows, perspective, or light sourcing. What we have featured in this article is a potential 3D version of the same fractal.http://www.skytopia.com/project/fractal/mandelbulb.htmljaeschke2009-11-17T09:01:02+01:003d fractal mandelbrot math todo <span itemprop="description">The original Mandelbrot is an amazing object that has captured the public's imagination for 30 years with its cascading patterns and hypnotically colourful detail.
