Orbital Solver

The OrbitalSolver namespace (GS_Core::Math) provides a stateless, deterministic, pure position / pose blend primitive. Given two positions (or transforms) and a pivot point, it blends them by a fraction t along an arc that preserves the geometric relationship to the pivot — rather than the straight-line lerp that cuts through the pivot when the start and end sit on opposite sides.

The primitive originated as a fix for PhantomCam cross-cam blends (two orbit cams at ~180° around a shared target produced visible “cuts through the target” mid-blend). It has since been reframed as the standard movement primitive for any motion naturally arranged around a pivot — orbit cams, leading-follow band response, post-config stage transitions. Linear lerp becomes the special case used only when no meaningful pivot exists.
