@Woven_Toyota | @NASAJPL | #threejs, graphics, open source, and a bunch of fun projects!
Tokyo, Japan
Joined April 2009
I've started a @Github Sponsors page to help support my open source contributions to three.js related projects like three-gpu-pathtracer, three-mesh-bvh, threejs-sandbox, and others! Sponsor here! https://t.co/om9ek9hNlZ

What are your favorite examples of documentation out there, especially for 3d libraries? What do they do well? I'm considering updating some of my project docs & am looking for inspiration. Even the little things make a difference. #threejs #webgl #javascript

Just implemented metric-aware Delaunay Triangulation on the sphere 🟣 Metric-aware => Every triangle respects the spherical metric, not the Euclidean one. Algorithm described below. #indiedev #gamedev #computergraphics #computationalgeometry #topology

I'm incredibly humbled to see three-mesh-bvh being used for physics in "Messenger"! What a phenomenal web experience ✨

Check out the view from up here! As the Curiosity rover continues to climb the flanks of Mt. Sharp, it has captured an extraordinarily clear panorama of Gale Crater's rim...and even the lands beyond. Details: https://t.co/Zv9gQzybLO

GPUs process thousands of pixels in parallel, but what happens when we write a single pixel to the framebuffer? How is it done? Watch a CPU paint each pixel in this amazing RISC-V visual simulator (load the bitmap example): https://t.co/sgv0sZQVva
Understanding GPU Architecture from Cornell https://t.co/54Lxi3Gw2I During a low-level discussion at a casual meetup, many folks were interested in understanding GPUs more closely. While CPUs optimize for complex control flow (see those big cores + caches), the GPUs maximize

After a year of scientific scrutiny, a rock sample collected by the Perseverance rover has been confirmed to contain a potential biosignature. The sample is the best candidate so far to provide evidence of ancient microbial life on Mars. https://t.co/0BAO1dhMG8

Been documenting my ass off all day, Doxygenating my fast-math library, SH4ZAM, targeting the Sega Dreamcast's SH4 CPU. My work on this project isn't as flashy as some of my other contributions or the things I've been involved with, but it has grown into what I believe will be
