sheafrelgeom 0.1.0a1

Small reference-frame transformations for relative geometric measurements.

sheafrelgeom

sheafrelgeom provides a tiny typed core for measurements expressed relative to named reference frames. It deliberately handles translation only, keeping the semantics explicit while leaving rotations, projections, and units to specialized packages.

from sheafrelgeom import Frame, Point, reframe

world = Frame("world")
camera = Frame("camera", parent=world, origin=(2.0, 1.0))
pixel_origin = Point("camera", (0.0, 0.0))

assert reframe(pixel_origin, camera, world) == Point("world", (2.0, 1.0))

Frames form an acyclic parent chain. reframe resolves a point through that chain and returns it in any related target frame. The package has no runtime dependencies and supports coordinates of any matching dimension.
