I specialize in highly detailed surgical scenes, and I have a lot of experience in drawing pathology, anomalous anatomy, and novel procedures. ✉️ m.rose.llewellyn@gmail.com 🫀 meganllewellyn.com
- Reposted by jbthe 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
- Reposted by jbAnd 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
- Reposted by jbAssuming 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.

- Reposted by jbEver 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

- Reposted by jbWith 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.

- really digging this for a light config UI
- fun to just play around and look at how the different distributions effect the color card

- 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".
- Reposted by jbAn 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
- 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
- Reposted by jbfav 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! 🧪
- working on some UI preview for spectral distributions
- what's cool is that with the use of gel filter data, I can actually quickly see the normalized filtered spectrum of the given distribution... this can be used to generate the iCDF to importance sample this particular light's spectral power distribution. there can be more than one filter in the stack

- Reposted by jbI 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

- Reposted by jbThis 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.
