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

working on some UI preview for spectral distributions

setup with Wenzel Jakob's "Low-Dimensional..Spectral Upsampling" to go from xRite color checker sRGB constants to spectral reflectance... then convolving reflectance, emission spectra, and wavelength color to get an approximation of the color card under that illumination

fav recent science fact: did you know that water strongly absorbs almost all wavelengths of light, EXCEPT for a tiny window right around the visible spectrum? this (+ UV radiation causing damage to DNA) is probably why the visible spectrum is visible to us! 🧪

I made a spectrograph to see if I can test my #astrophotography filters. How good is it? Hint: there are probably tweaks I can do to make it better. Video out now. youtu.be/6EeD9ejpDzY

This reflective acrylic sheet shows how 1980s illustrators were able to trace real-life objects on the computer. Once it was aligned, it reflected whatever was in front of it over the monitor's display, allowing artists to trace it in a tool like MacPaint or MS Paint. Simple, low tech and effective.

it's interesting, some of the multiple-refraction interactions start looking like iridescence

volumetric shadow mapping from a single camera render. computing the volume shadows is O(log(voxelResolution.z)) complexity

Gaussian splats are quite the rage lately (for good reason). Yet the technique is actually quite old!
 35 years ago, Lee Westover created the worlds first splat with the “UNC Head” dataset. A high-res CT scan...much too detailed for computers at the time.

amazing how much a -1 can mess up your whole thing - refraction is now using the real geometry instead of some weird mirror world

some of the better renders I've done, I think

fixed up some color management issues and now getting much, much better results
