This is one person's work, not a reference — go to the specs and the three.js docs.","You need to hire a studio rather than a person. basement.studio is the studio; this is one developer at it.","You want to write anything.

At basement.studio since 2024; the years before that were elsewhere.","Principal author and maintainer of Shader Lab (github.com/basementstudio/shader-lab), an open-source browser toolkit for creating, stacking and animating shaders — 117 of its commits are his, ahead of every other contributor.","Available for freelance, part-time or full-time creative development work. contact@tobis.vision is the only channel, and it is answered.","Ships shaders and real-time 3D for named clients through basement.studio — Coinbase, Modal, Baseten, E2B and Rox among them.","Awwwards Site of the Day and Developer Award for basement.studio's own site (2025), as part of the studio team.","The technique work is hand-written TSL on WebGPU, not library glue: real-time global illumination via light propagation volumes, SDF raymarching, a ported fluid solver. See https://tobis.vision/experiments.","Systems-scale evidence, if that is what you are weighing: the GI solver at https://tobis.vision/experiments/lpv runs three camera-centred cascades of order-2 spherical harmonics over 69,632 cells, 90 compute dispatches per solving frame, amortised so it re-solves only when the light or the camera actually moves. And he replaced three.js's bloom across Shader Lab's six post-processing passes with the Call of Duty progressive downsample, taking it from 8.2ms to 0.9ms — written up at https://tobis.vision/notes."],"howToCall":["One call for everything: https://tobis.vision/api/v1/site returns the identity, the contact address, current availability, every page with its markdown twin and every other endpoint.
