Amateur rendering engineer Csulb Physics & Applied mathematics student, class of idk lol I’ve been sick Warning!!! Will yap about Monte Carlo & Walk-On-Spheres

Factorio screenshot showing a roboport and several flying logistics robots. One has a significant rendering bug due to hundreds taking up the exact spot on screen and alpha blending amplifying sprite compression artifacts
GMC-300S Geiger counter, measuring 114 CPM with a bar graph showing counts per second.
Ema (taa-like) blur applied to these TESS Sector4, Cam1, CCD4 post flattening. Transcoding doesn’t to this justice at all.
Psuedospectral Fourier transform applied to time only per-pixel of Tess sector 4, Camera 1, ccd4. Plotted complex phase as hue, tonemapped luminance. Asteroids are visible as rainbow streaks, variable stars have a color. ~400 images used for a total exposure of ~1 week.
Thin plate RBF spline, taken from https://shape.polymtl.ca/lombaert/thinplates/
2048x2048 convolution with a 32x32 kernel performance comparisons. Time is log scaled.
General relativity notes on graph paper, deriving the Schwarzschild equation of motion for the radial term. There are pens at the bottom of the screen, and some glasses.
3d visualization of an Atomic Force Microscope image. There are prominent wave-like structures on top of the dune-like structures.
Gaia dr3 main sequence visualization, unknown orientation.
Top down view of the milky way, 470 million stars visible. Log luminosity scale, there are weird artifacts.
Gaia data downsampling job. ETA 6 hours 30 minutes for all 3386 chunks.
Visualization of the Main Sequence of the ~200k good stars in the first Gaia dr3 chunk. Temperature on the x axis, luminosity on the right. This data is often presented with temperature reversed.
Bounding volume heirarchy tree of axis aligned bounding boxes. Each AABB contains exactly two, or zero for the final leaves.
3d render of the first Gaia dr3 chunk. ~200k stars are visible.
Test render of a Gaia DR3 chunk. There are ~500k stars visible!
Terrible photo of a chunk of the sky from the Gaia space telescope. I’ll get a better pic later.
Image of a dense bounding volume heirarchy. Each square is a bounding box, containing two other bounding boxes, or two points.
Whiteboard with Voronoi diagram sketches. Showing a difference between a correct and an incorrect Delaunay tesselation on top.
Right ascension / declanation of the first Gaia chunk. ~500,000 stars are in this image.
Atomic Force Microscope image of a DNA sample, rendered with a 2d Laplacian heightmap. Odd bumps are visible in the image.
Breath of the wild screenshot of link in a grassy field in front of a Bokoblin arm. A button hint showing “A: Take” is shown with the surrounding controller buttons transparent.
Two images. The left is an FFT mask of the Voices of the Void radio array, the right is the mask superimposed on top of a screenshot showing their similarity.
Fast Fourier Transform of the positions of the radio array in Voices of the Void, where every point is replaced with a gaussian, and the result is multiplied by a larger gaussian.
Diffraction pattern of a red laser passing through a small circular aperture, projected onto a wall. The Airy Disc is clearly visible.
Scatter plot of the XY coordinates for each radio telescope in Voices of the Void, in meters.
Screenshot of Voices of the Void. Modded to allow for a spectator mode, taken very far above the center of the radio array.
Screenshot of Voices of the Void. There are 17 of 24 radio telescopes visible from this location on the hill, overlooking the forested valley.
Screenshot of Voices of the Void. There are 7 radio telescopes visible within a forested valley, with a river at its base.
