    This shows the first step of the sparse virtual texturing algorithm applied to a globe with 256x128 image tiles organized into a quad-tree. The shader used to compute the required texture resolution across the globe runs in a webworker with OffscreenCanvas + WebGL. #threejs

    It's alive! My first custom-made circuit board, controlling one of the valves for our balcony-gardening project. Oh, and for obvious reasons it's going to be programmed in JS (low.js on an esp32) :)

    12M triangles – loading ~300MB of vertex-data into several three.js geometries. To improve performance, the attributes were basically memory-mapped from the fetch-API to the GPU (doesn't even stutter while loading). Raycasting is done using depth- and normal-maps.

    To draw paths on the rock surface and arrange text meshes in 3D, @usefulthink developed a browser-based tool that can stream and handle all the 37 million vertices of the scene. Here is a quick screen capture:

    Dear meetup/conference organizers, please do not use zoom exclusively. "The meeting requires registration to join and it is not supported to join from the browser." - I'm good, thanks.
