How to solve a #pentomino in 20 seconds.

Okay not really, I knew what the solution was, just animating it with a little recreational #javascript using #threejs 3D rendering, It's also using my garbage homemade NES dither shader to mimic the limited color palette.

Video is potato quality, but it's actually pretty nice on my screen when it's sharp and crisp.

I can feed any solution to it from https://isomerdesign.com/Pentomino/6x10/solutions.txt and it'll just animate it. Can you see why this is my favorite solution?

Some performance improvements incoming - focusing on a smooth multi-body space engine has been my focus as I took a few days to just clean up code, APIs and - happily running at 120fps (at 96x speed - where the n-body physics is still relatively stable) - the main bottleneck is now in the WebGL rendering itself!

Now when you load our solar system in #teskooano it calculates the actual position based on the epoch (like J2000 or later), TLE telemetry lines for earth-centric satellites, or Legrange points like L2 for JWST to create a live #ephemeris

New Github PR to #ThreeJS that adds much improved #MaterialX support.

New nodes & properties supported: thin film, sheen, transmission, rotate, determine, inverse, floor, reflect, refract, opacity, specular, anisotropy, etc...

Updated my older room builder code to use a modern #threejs version. Using placeholder assets from @kenney . At some point the plan was to automatically convert floorplan drawings to 3d scenes. But the client I was doing this for pulled out. Never finished. But over the years I've been using it as a playground and toy box a bit

New #satellites in #Teskooano - now with correct models like the #iss and #jwst with correct lighting model - now live on https://teskooano.space

Something for the next release of #teskooano I'm cooking up - man-made celestials!

Here is the ISS close to Earth, and a Geostationary satellite - using a single model for it for now, but hopefully will be able to add a more detailed one soon (especially for the ISS)
