@Pontebata ¿No se basa en incinerar la muestra, acelerar los iones y doblar su camino con un campo magnético? No veo por qué no se puede miniaturizar :-)

@yombo Hostia yo creo que por el propio funcionamiento de un masas es imposible adaptarlo a algo que quepa en el bolsillo 😅

@Pontebata Hola, ¿Tienes espectrómetro de masas? ¿Existen USB de ellos? ¿Podrías recomendarme alguna marca o tienda para uso amateur? Aunque consideraría precio alto ya que tengo especial ilusión por tener uno desde hace tiempo.

@Pontebata Te juro que en el laboratorio de un hospital vi uno que hacía 20x15x5cm. Ponía spectometer, lo vi a 1 m de distancia durante unos segundos. Pero el tamaño no importa xD Sino el precio.

Han publicado los chicos de @BlenderStudio_ el nuevo corto: "Charge". Renderizado en Eevee y usando características recién lanzadas en Blender, es de los mejores trabajos del estudio. youtube.com/watch?v=UXqq0Z…

Absolutely insane new ZX Spectrum demo: youtube.com/watch?v=eEOv-O… (also @iquilezles check out 2:00 - cheeky buggers!)

More ragdoll physics tests with bullet.js. Characters now smoothly change direction by setting gravity.x/z of their arms. 🙂 #bulletjs #threejs #javascript

@mrdoob I call it the tendency to "simplify interfaces". I see it everywhere.

Yep

@mrdoob I use Tweetdeck (multiple columns), but the polls don't work now in Tweetdeck, it redirects me to the main site.

What timeline mode do you use?

@armbian RPi4b runs fine...

@garrettkjohnson (Only math classes, not WebGL code)

@garrettkjohnson That's why I made a minimalistic C++ OpenGL/OpenCL engine last year just to make a voxel editor suite. It is not published (just for personal use) I took #threejs code borrowed.

v0.5.18 of three-mesh-bvh has been released! It includes a GPU closestPointToPoint function which can be used to generate SDFs & more! The attached image shows layers of a 3d volume texture with signed distances to a mesh. github.com/gkjohnson/thre… #threejs #webgl #raymarching

@garrettkjohnson Certainly I could use 1 bit per voxel so, you're right, it fits. (My 3060 has 12 GB)

@garrettkjohnson 🤔 at 1 byte/voxel it would be 13 GB. Where do you get the 5 GB from?

@garrettkjohnson (My printer would have 13 billion voxels at most)

@yombo You could try but I would generate a 3d texture and then ray march that, I think. That will be faster than generating the slices on the CPU like you were doing previously, too

@garrettkjohnson But the slices could be generated in GPU indeed.

@garrettkjohnson The voxels of the resin print are tiny (50 microns) so the texture won't fit in VRAM.
