Apollonian Gasket

Choose depth 0–10 with the slider. Each level fills all remaining gaps with tangent circles. The fixed seed and Descartes reflection are deterministic. Depth 10 contains 118,100 circles.

Ctrl/Meta + wheel zooms about the view center. Drag with the mouse to pan. Reset fits the whole packing. PNG exports the current view. Only the chosen depth is kept in this browser; results and the view are not saved.

The calculation retains every circle at the chosen depth. Drawing is batched so large packings remain responsive; circles outside the view do not need to be drawn. Geometry uses floating-point arithmetic, not arbitrary precision.
