dsh-blackhole Read this in: English · 简体中文 · 繁體中文 · 日本語 A geodesic-traced Schwarzschild black hole floating inside DeepSeek Harness (DSH) — a persistent client plugin for the DSH web surface, ported from s0xDk/ghostty-blackhole (Ghostty custom shader, MIT). The black hole lives on a click-through WebGL2 overlay above the page: every near-field pixel integrates its own null geodesic through the Schwarzschild metric (Binet form a = -(3/2) h² x / r⁵ ), so the shadow, the accretion disk, the photon ring, and the gravitational lensing are all emergent from the ray tracing — nothing is painted on. What it renders - The shadow — rays under b crit = (3√3/2) r s spiral in and come back black. - Accretion disk — thin Keplerian disk with a Shakura–Sunyaev temperature profile, relativistic Doppler shift and beaming ( g = √(1 − 1.5 r s/r)/(1 − β·k̂) ); the far side arcs over and under the shadow (the Interstellar look). - Photon ring — rays winding near the 1.5 r s photon sphere. - Gravitational lensing — with the optional Sky background on, escaped rays project onto a procedural starfield "sky" plane (browsers cannot sample page pixels into WebGL); the far field uses the analytic weak-field de…
