varying size spherical (+hemispherical) elements

current perf on laptop GPU

when in denser materials (read: a soup of many overlapping shapes) you can see this a lot more... parallel sources split into coherent beams while diffused sources like those in the middle here seem to diffuse in a more natural looking way

bug with DDA traversal, rays that start outside the grid incorrectly take max distance... but it makes it look like there is a 3D component

@mmalex.bsky.social that cauchy distribution keeps giving, using it for adjusting initial ray directions in 2D PT

spectral pathtracing on a nest of short line segments, mixed mirror and glass materials

implemented a grid-based acceleration structure for the spectral pathtracer (to replace SDF scene intersection), which allows for huge explicit primitive counts, runtime interactive user edits, and runs >10x faster

Happy, new month? I guess...? ANYWAYS!!!!!! We're beyond excited to announce that we're shifting our timeline forward 20 years! This means all the cars will now be from the late 90s and early 2000s!! This is 100% real news!!! You can check the "new" fleet we've prepared below!!

Hi #portfolioday ! I'm Megan Llewellyn and I'm a freelance medical illustrator available for new work! I specialize in highly detailed surgical scenes, and I have a lot of experience in drawing pathology, anomalous anatomy, and novel procedures. ✉️ [email protected] 🫀 meganllewellyn.com

the 2nd part of my dithering visual article is finally out! 🔗 visualrambling.space/dithering-pa... this one mainly explores the threshold map and how it generates those unique visual patterns hope you enjoy this as much as I enjoyed making it! made with #threejs & #animejs

And one of my very first works in the PSX low-poly style. As for me, this is the simplest direction of 3D model design, but also the most interesting) skfb.ly/oT6Wp

Assuming uniform weights and frequencies, and random colors and anisotropy directions, this is what an example gaboronoi diagram would look like.

vkCmdBlitImage2 is an extremely cool feature - if there is not a 1:1 pixel correspondence between src and dst, it actually uses the texture hardware to do a copy. Really interesting mix of high and low level feature, would typically have to write a little shader to do this.

An interactive digital magazine in 320x200 pixels. Never published - but this was a proposed design for a Commodore 64 magazine. #ux #digital #design #8bit

Ever seen one of these, and wondered *why* they work? 🧵 This is a so-called Bitonic sorting network, and the illustrations show the two common ways to implement them. From an implementation point of view the two methods are effectively the same, so which one you pick just comes down to preference.

converted 3D physarum from DDA traversal to delta tracking and seeing a roughly 2x speedup in the worst case when there is a lot of scattering

this is something I came across in the xRite literature. The qualitative saturation difference actually corresponds to the emission between the two illuminants - xenon has more wideband activity, and so it is "less saturated".

Time for more Menu Cube posting 😌

With my rtgi i am also doing something, that i believe, is a novel technique that i have not seen done before. While probes are often used in rtgi for indirect diffuse on hit shading, i use them to replace all rtgi hit shading. On each hit i project the closest probes radiance into the hits.

An analog calculation: All the code, all the mistakes, all the debugging, all the documentation ... all on a single sheet of paper! :) Physics of the gyroscope again: this time Poinsot's ellipsoid rolling but not slipping in the plane defined by angular momentum. #MathArt #SciArt

picked up a swatchbook of filters corresponding to the gel data I found. cool to see the correspondence... saturation differences, I think here is because of the CRI of the LED relative to the xenon curve I have
