About & licences

Parallax is a projection-geometry teaching lab using simplified models. Not for clinical use. The models are not anatomically validated and the lessons have not been tested with learners.

Images use idealised attenuation without scatter, soft tissue, spectrum, blur or detector noise. Pixel edges can shimmer. The rig does not model machine travel or collisions. One view, or a pair that looks reassuring, is not a general test of containment.

Original work

Code, documentation and model assets use the MIT licence.

Three.js

The 3D scenes use Three.js 0.186.0: MIT licence · version record.

Estate theme & fonts

The shared Sangeev.me theme is @sangeev/estate-ui 2.0.0-alpha.7, under its MIT licence. Literata and Atkinson Hyperlegible Next are bundled under their SIL Open Font Licences. All runtime assets are served locally; no font service or CDN is used.

Models

The cylinder and wire are mathematical shapes. The femur, ftv-proximal-femur-left-v001, was generated from sphere/capsule fields using marching tetrahedra, not scans or downloaded anatomy. Its original triangles and artificial distal cap are unchanged.

The source package reproduces projections from these exports. It includes model hashes and instructions, but not the Windows/Blender authoring workspace.

The femur renderer passed the recorded numerical checks but missed the 256² / 250 ms interaction target: a PARTIAL result. It remains an experiment.
