pub fn cap_intersection_area(

Expand description

Solid angle of the intersection of two spherical caps.

Given two caps (center_a, α_a) and (center_b, α_b), computes the solid angle of their overlap region on S².

Uses the analytic formula for two-cap intersection via the lens integral. Returns 0.0 if the caps don’t overlap.
