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.
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."

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

more working on generated villages. some of these rules are really close to consistently generating sets of linked rooms and walled gardens..

Writing code on a bumpy train and tried stabilizing the display image to my head -- it does (surprisingly) make things a bit easier to read but overall feels too weird to actually use.

The post on using spatial hashing with raytraced ambient occlusion attracted quite a bit of interest so I expanded it into a blog post to discuss how it works behind the scenes to both reduce the noise and its cost. interplayoflight.wordpress.com/2025/11/23/s...

My third and final blog post on spectral rendering is out. This one compares results of RGB and spectral rendering under different illuminants and draws conclusions.

So it is possible to do 60fps 3d on the sega megadrive by using a very exotic indexing method to simulate 2 colors + alternating lines + fast DMA. Totally interlaced my brain 🙃
