🎗 PSA Kinetics Doubling Time — 3D

A genuine 3D companion to the PSA Kinetics Doubling Time Monitoring Simulator: the same exponential growth model, PSA = PSA₀ · e^kt, and the same log-linear regression for doubling-time and risk, replayed live as a real 3D bar-chart timeline and a growing tumor-cell colony you can orbit freely in WebGL.

⚙ Under the hood

This is the same clinical kinetics model as the 2D PSA monitor: serial PSA draws every 3 months are generated from PSA(t) = PSA₀·e^kt with realistic ±9% assay noise, then fit with a log-linear regression of ln(PSA) against time to recover the doubling time PSADT = ln(2)/slope — exactly the calculation used in real biochemical-recurrence monitoring. In 3D, each serial draw becomes a real extruded box on a log-height timeline (not a flat plotted point), a translucent red plane marks the 0.2 ng/mL recurrence threshold, the regression fit is a lit 3D tube, and a separate instanced sphere colony grows and shrinks in true spherical 3D space in proportion to the live modeled PSA value — all inspectable from any angle via free camera orbit.
