Resonance Chamber

A full 16 × 16 × 16 acoustic volume. Opposite pulses start at different heights and travel through a double-aperture reflector; the outer layer absorbs energy. In Studio, open View options and choose Single layer or Cutaway on X, Y or Z to reveal the interior. Paint Crest or Trough into empty cells to add a pulse, or recompile to restore the initial scene. This is a stylized scalar wave model, not a fluid solver.
