- Worth noticing
- The field manual gives the geodesic equation and says the image uses no sphere mesh or ring texture.
Field notes
The field manual specifies an adaptive RK4 integration of null geodesics and gives the equation used for the Schwarzschild metric. Its listed control deck includes 21 parameters, 10 debug views, four camera presets, PNG capture, and a shareable state URL. The page describes GPU rendering, but the captured state reports a lost WebGL context and a WebGL 2 initialization failure.
