Adaptive interpolatory curve subdivision with learned per-edge insertion angles, evaluated across the Euclidean plane, the two-sphere, and the Poincaré disk. The classical fixed-tension parameter is replaced by a learned local-angle predictor, while interpolation is preserved as a structural property of the operator.
