Truly! This looks pretty neat too - though i wonder how @vrkomarov.bsky.social is avoiding denoising on the volume

Finally, I came around at implementing DOF and wiring it to the camera manipulator system. Click and drag to samples the scene to estimate the focus distance, while scroll to modulate the aperture.

Hey All, I made a header only C++ library (MIT) where line of code inits, then you can start writing to pixels on the screen.

I call it thirteen.h, inspired by the simplicity of the 13h days.

Examples include a mandelbrot viewer and a playable mine sweeper game.

I think about this a lot

It’s sad to see you leaving here. Your work has been incredibly inspiring and good to learn from

are you stepping away from social media?

black and white illustration part of a series on pancreas preserving duodenectomy. the gallbladder, part of the liver, part of the stomach, gastric artery, pancreas, and duodenum are visible. the duodenum wall is cut away to show precancerous growth in the lumen and the ampulla of Vater

black and white illustration showing the surgical scene for a nephrectomy and thrombectomy to treat renal cell carcinoma. the chest and abdomen have a long incision to expose the heart down to the right kidney with the liver and other organs retracted. the kidney is enlarged and the inferior vena cava is enlarged and cut open to show a large thrombus that extends superiorly into the right atrium, which is also cut open to visualize the clot.

black and white surgical series of an aortic arch aneurysm repair. the main illustration is of the surgical scene with a clam shell thoracotomy to expose the heart, lung, and aortic arch. the bottom left inset shows the aortic arch having been excised and a graft in process of being sutured in place and the bottom right inset shows the final graft repair.

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.

Seattle people - want to get a nice hand made bowl and help feed people in need?

Doesn’t look like I can start DM with you, send a message and I should be able to reply

Any chance you’re still searching for new work opportunities?

-- JOB SEARCH POST/RT APPRECIATED --
Hello everyone!

I am available for work (full time position/internship) anywhere in the world with priority going to the EU, starting June 2026. 🧵

Nice! Is the division a result of reflecting the ray about some mirror planes, like Noah was thinking?

BIG FIGHT AT POLAND’S WROCLAW ZOO!!!

May 2026 be better, safer, and fairer. May all that was good in 2025 be better in 2026. May all that was bad in 2025 be things we put our efforts towards improving.

Blink Twice may be a good watch in that case

Another algorithm tutorial with great visuals - just in time for holiday break!

interesting - this spectral renderer is a hop, skip, and a jump from simulated crystallography (someone I know recently did some work related to simulated crystal growth jbaker.graphics/writings/cry...) - this is a physical, real process used to identify crystals via their diffraction patterns

I spend 1.5 years doing this. Full rewrite last summer and another partial rewrite last month. As Hemingway said: "First draft of everything is always shit".

Someone on twitter writes: "You could move to Aplington, Iowa and get a job at the post office making $25 an hour to start, meet a nice girl at the First Reformed Church and take her on a date to Stinky's Bar and Grill, and get married and raise up seven children in this house but you will not do it." There's a screenshot of a Zillow listing showing a rundown 8 bedroom, 1 bathroom home for $95,000.

If you want to do something like this, why not buy a $150k home in a small town in Italy, France, Spain, or Mexico, instead of having nine people share one bathroom after they eat at a restaurant called "Stinky's?"

Spatial warps remap the positions used to sample an object’s distance field – effectively bending the space around the object.
This illustration shows that process in action using a twist operation.

Decided to go back to making Shadertoy fluid sims for for a bit.
This time I improved my particle clustering cellular automaton SPH fluid sim to support multiple species particle merging and splitting. Also some fine tuning of the physics.

seems like in this situation the post is a flat out lie

In the richest city in the richest country on the planet, the thing we can’t afford is to forget those who are left hungry.

First test with ReSTIR, just for direct lighting for now. Figuring out the weights was a bit finicky, ngl. This scene is a bit too easy since all light sources are in the same spot, gonna try placing a bunch of light sources tomorrow.
