Projectors

Canonical projectors

GnomonicProjector and CubemapProjector are immutable reusable objects from panorai.geometry. They retain only their spec, interpolation mode, and fill value; all computation delegates to the canonical functional engine.

Use GnomonicProjector for a rectilinear tangent view. Use CubemapProjector for the fixed face order front, right, back, left, up, down. Functional and object-oriented calls have the same coordinate contract.

Legacy registry

The name gnomonic remains available through the 3.0 compatibility registry. It does not define new canonical geometry. Prefer panorai.geometry.GnomonicSpec in new code.
