What This Shows / What It Does Not Show

What This Page Establishes (Evidence Level: Capability inventory (no empirical validation))

• Which tools and programs are listed here, and the capability state (Available, Experimental, or Planned) of each.

What This Page Does Not Establish

• A guarantee of Rotation Representation Converter behavior for undeclared conventions or arbitrary invalid inputs; availability is not such a guarantee.
• That the Wrist Universal Joint Model is an identified anatomical wrist, a tissue-load estimate, or a clinical tool; it is a mechanical teaching model.

What the labels mean. AVAILABLE means the linked item exists and you can inspect it. EXPERIMENTAL means we are still checking how it behaves. We may also still be checking what the model covers or where it runs. Neither label means a result about the body has been validated in people. Read more in How to Read This Site: Publication States. Canonical desktop and web tools are published by the Tools repository (pinned commit f0112a4b); see the Tools Repository Catalog. What the UpstreamDrift software can do is documented separately on the Overview page.

Mathematics & Kinematics Tools

Rotation Representation Converter Available

A browser calculator for five ways to describe a rotation: rotation matrix SO(3), unit quaternion, ZYX Euler angles, axis-angle, and exponential coordinates. The linked page states its conventions and where it breaks down (its singularities); maintains verified golden-vector parity with the canonical Tools rotation_converter suite.

Golf Biomechanics Tools

Wrist Universal Joint Model Experimental

An interactive, simplified joint model. Use it to see how grip and wrist angle change the torque that the model passes along.

Wrist Universal Joint Model (PyQt6) Experimental

Daydreams & Doodles Experimental

Exploratory models and demos in biomechanics, fluid dynamics, and passive dynamics. This work sits outside the core AffineDrift research track.

Dead Fish Swimming Upstream Planned

An experimental reading note. It looks at how a swirling wake can push a body along passively. Its comparison with mechanical drift is an editorial analogy. It is not a result showing a shared mechanism. Expected: 2026-Q4.
