the gradient up from the center helps accentuate the subsurface stuff going on... it's just a crazy number of glass balls and a crazy number of bounces

melting point somewhat high, that's too bad - neat stuff though

you wouldn't happen to know anything about what the purple ceramic they used to use was, would you?

kinda neat, using cloudcompare to gather crystal point data + remove neighbors within some threshold, to condition data for representation by a collection of slightly-smaller-than-that spheres

arxiv.org/pdf/cond-mat... another interesting paper, tracing back some references - this one introduces something called the Hastings-Levitov Algorithm, which moves to the complex plane... there apparently was interest in this algorithm from scientists at ExxonMobil, too web.njit.edu/~kondic/caps...

interesting to reflect on 10^6 being a genuine supercomputer scale problem back then - the slowest GPU I have is capable of orders of magnitude more computation

stumbled onto prior art on oriented DLA - 30 year old paper by Benoit Mandelbrot - more stochastic than my approach, very interesting - too bad it is missing the figures

I am glad higher ed is remaining somewhat intact - I am hearing very, very concerning things from friends in early childhood education, reading really is out the window in a lot of cases

Every so often we get asked why don't we use our 64k tech to make a game, or give it to people to improve existing games, and it's very hard to explain that That's Not How It Works.

A screenshot from a Computer Graphics white paper dubbed "Pyramidal Parametrics" by Lance Williams, 1983. It looks at mipmaps as a concept. The screenshot here shows two dark images. It consists of black background with exploded cubes on top. On each side of the cube, imagery is mapped. One looks like an eye, the other like an overexposed coin, and the other one like 4 heads next to one another. It all has creepy colors and visuals. Under it reads "Figure 8-9" Sunstone by Ed Emshwiller, segment animated by Alvy Ray Smith
Pyramidal parametric texture mapping on polygons."

Reading old computer graphics white papers is super fun because every so often you come across the most liminal, weird looking images. Like this one from 1983.

Here is another fun example of what one could do with the symmetry operator.
On a related note... I do love my job! :)
