Sources and simplifications
  • This is fiction. The walker is an original model built from code in the spirit of the design, not a film asset or official blueprint.
  • Interior layout is illustrative. Canon names the crew, troops, speeder bikes and guns [1][2], not a deck plan.
  • The walk is a lateral-sequence gait: one foot in the air at a time, the slow, stable gait of large quadrupeds. Knees bend forward. Leg angles come from two-bone inverse kinematics, so every planted foot holds still on the snow as the ground slides back beneath it.
  • Footprints are pressed into a live heightfield as each foot lands. They drift back with the snow and fill in over about half a minute.
  • Scale is about 4 cm per unit, which puts the roof near 22.5 m, the height Wookieepedia gives [1].

Hatched faces: the walls the slice cuts throughA highlighted department: click it for its cardFootprints pressed into the snow, drifting back as it walksAn all-terrain armoured transport walking in place through snow. It is fiction, built here as an original procedural model after the canon design [1][2]. It walks one foot at a time: each leg's thigh, knee and ankle angles are solved from where its foot must be, so a planted foot stays still while the snow slides back beneath it. Each landing presses a print with a raised rim into the snow, and older prints fill in. Turn on the slice and move it through the body from the side to see what lies inside: the cockpit in the head, the neck corridor, the troop bay, the speeder bike bay, the generator and the leg drives. Click any of them for a card explaining what it does. Canon gives a crew of 3 in the cockpit, about 40 troops and 5 speeder bikes [1]; the deck layout shown is illustrative.
