About Singularity Torus

Singularity Torus renders a luminous torus (donut shape) orbiting a gravitational singularity, with light bending and distorting around the central point in response to your music. The torus itself is an audio-reactive energy field: its major and minor radii pulse with bass energy, its surface emits light patterns driven by frequency data, and particle streams spiral off it following curved spacetime trajectories. The gravitational lensing effect around the singularity is the visual centerpiece. Background elements (starfields, nebulae) are distorted through the warped space, creating the characteristic Einstein ring and photon sphere effects seen in scientific visualizations of black holes. Audio energy controls the singularity's apparent mass, which modulates the severity of the lensing -- loud passages create extreme distortion while quiet moments allow the background to appear nearly normal. Singularity Torus merges astrophysics with audio art. The interplay between the glowing torus and the light-eating singularity creates a visual tension -- creation and destruction, light and darkness -- that mirrors the dynamic tension in music between energy and silence, tension and release.

How it works

The torus is a parametric mesh with per-vertex displacement driven by frequency band energies. Surface emission uses a procedural pattern shader with audio-reactive parameters. The gravitational lensing is implemented as a screen-space post-processing effect: a ray-bending shader computes the deflection of each pixel's view ray around a point mass using the Schwarzschild metric approximation. The deflection magnitude is modulated by bass energy (controlling apparent mass). Particle streams use GPU-computed trajectories that follow geodesics in the warped space. The accretion disk is rendered as a flat ring of particles with Doppler-shifted colors.

Frequently Asked Questions

Is the gravitational lensing realistic?+
The lensing uses a simplified Schwarzschild metric approximation that captures the key visual features (Einstein ring, photon sphere, light bending) without full general relativistic ray tracing. It is visually accurate enough to be educational.
Can I adjust the black hole mass?+
The base mass (and therefore base lensing strength) is configurable. Audio energy modulates around this base value, so you control the overall intensity of the gravitational distortion.
What happens at peak audio energy?+
At maximum energy, the singularity distortion becomes extreme, bending the torus light into dramatic arcs and creating intense gravitational lensing of the background. The effect is visually spectacular without being disorienting.
