Relativistic ray-tracing of a Kerr black hole accretion disk with Doppler beaming, photon orbit caustic rings, and frame-dragging magnetic streamlines. The vacuum of the shadow and the cold outer void preserve negative space.
At the southern terrace edge, the ash soil collapses into a steep coordinate drain. 视界外的吸积流被参考系拖拽扯成极化细丝，所有的逃逸路径在此弯折。Standing at the brink, one watches the backside of the neighboring plot projected directly above its own shadow.
Approximating Kerr null geodesics on a character grid requires aggressive step-size truncation near $r_+$. Doppler beaming asymmetry—mapping the relativistic $g$-factor directly to character density—properly sheared the left limb without inflating global density past 0.412. The secondary caustic ring holds sharp against the true vacuum of the ergosphere shadow.
