A three-dimensional (3D) display system may include a peg array of multiple pegs. Each peg may be individually addressable and designed to move along one or more axes. The 3D display system may also include an induction array having multiple electromagnetic coils to generate electromagnetic fields. The electromagnetic fields may induce magnetic forces upon at least one peg to cause the peg to move along an axis into an actuated position. The 3D display may also include a display screen to be distended into a 3D topography via contact with at least one peg in the actuated position.
