jumpsplat120′s amazing letsplay of my upcoming 4D puzzler, Tetraspace. He does a good job at trying to explain the mechanic behind exploring the four-dimensional world.

From Tetraspace, a four-dimensional game.

Experiments in Processing: hyperbolic flower

Growing a hyperbolic plane. Don’t overwater.

Experiments in processing: Dark side of the Moon

A physically accurate homage to Pink Floyd. It’s 2d spectral raytracing with Fresnell/Snell diffraction; the raytracing runs in Processing itself. Many random samples are taken per frame and additively blended.

Wavelength -> RGB approximation uses the algorithm in http://stackoverflow.com/a/22681410

(while the baseline index of refraction in the simulation is typical for glass, dispersion is unusually high for aesthetic purposes)

Experiments in Processing: eight-figure through a cube.

This is the famous eight-figure orbit in the three-body problem as described in http://emis.matem.unam.mx/journals/Annals/152_3/chencine.pdf.

This orbit, though unlikely, is astonishingly stable.

A heavy render for an upcoming Hacker Monthly article.

Experiments in Processing: curious eels in hyperbolic sea.

I love hyperbolic geometry, heptagons, and Escher.

The eels move on the sides of a triheptagonal tiling of the hyperbolic plane in the Poincaré disk model. You better appreciate this because getting the coordinates is a real pain in the *** (done with a python script, <a href=“https://github.com/rantonels/poincare“>source</a>).
