Ski anatomy in 3D

A full 3D skier driven by the same turn model as the rear, side and plan diagrams. X-ray shows the muscles and skeleton through the body; Skier shows the dressed skier. Drag the large view to orbit. The three small views stay locked to rear, side and above.

Top bar is the outside side, bottom bar the inside side. Hover a muscle here or on the skier to highlight it.

A simplified, illustrative model. The carved turn flexes to release and extends through the turn. The wedge turn holds a matching wedge on inside edges and steers mainly by turning the legs. Angles, loads and efforts follow the shape of real technique but are not measured data.
