Space Anomaly Field: Gravitational Lensing & Ray Deflection (2D)

Point-mass space anomalies bend a field of light rays through real Newtonian inverse-square gravity — tune anomaly count, mass intensity, ray density and a detection threshold, then watch rays curve and get flagged as their deflection angle grows.

The 3D original is a decorative slider dashboard — its "anomaly", "intensity" and "frequency" controls only randomize opacity and scale on a scatter of meshes, with no formula connecting them. This 2D companion keeps the same anomaly-field theme but drives it with real physics: each anomaly is a point mass, each light ray is a free-falling test particle integrated step by step under Newtonian inverse-square gravity from every anomaly in the field, and the on-screen deflection angle is the ray's actual accumulated turn away from its initial straight path rather than a random number.

Why does a ray sometimes loop back instead of just bending slightly?

If a ray passes close enough to a high-mass anomaly, the inverse-square pull grows fast enough (softened near-singularity aside) that its velocity vector rotates by a large angle in a short distance — the same qualitative behavior as a close gravitational flyby.

What does the detection threshold actually measure?

It's a cutoff, in degrees, on the ray's accumulated deflection angle (the angle between its current velocity and its original horizontal heading). Rays that cross it are flagged and counted in the "Detected" readout.
