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

- 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.

- 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".

- 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 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.

This is true and I was the only one on set excited about it (and playing the song on my phone to blank stares) - Reposted by jb[Not loaded yet]

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