Shared twin
THUMS AM95 surface · provisional retarget · forearms and lower body are display priors.
Skin & garment motion
Face arrows show observed image motion minus fitted rigid-head motion. Mesh vertices without local texture support are inferred. These layers are separate from the anatomical body.
The optional facial skin candidate uses a local THUMS surface and weak frontal landmarks. It does not move the inferred skull or estimate tissue mechanics.
Precise source review
Choose a landmark, then click its location in the large source image. Review edits are kept separately from the frozen fitting benchmark.

Body image predictions
The table summarizes the first body campaign; the plot uses the body Fit selector. Separate head-only comparisons are reported below. Native pixels use the same eligible references within each experiment. Historical annotations are not independent 3D truth.
Camera sample timing
Each tick is an encoded source frame mapped onto the selected fit’s shared clock. Shaded bars show how long the viewer holds a frame; they are not camera exposures. Exposure duration and rolling-shutter readout remain unknown.
These trajectories use provisional length units. Angular motion is evaluated from 3D rotations. Numerical bandwidth and camera omission produce different accelerations; this is sensitivity, not a confidence interval.
The export pairs one shared trajectory with its fitted wrists, exact surface transforms and camera projection matrices. Physical scale and mechanical properties remain unset.
Physical scale remains provisional. This viewer shows a kinematic reconstruction and a retargeted anatomical exterior. It is not a validated finite-element simulation, a measurement of tissue strain, or an identified impact force.
