Underwater exhalation
Figure 6 caption
Underwater character exhalation produces a cascading plume of nonspherical bubbles, yielding a classic underwater sound. See the supplemental video for sound comparisons across bubble-frequency models.
From Section 6, “Underwater Exhalation”
A character exhales air underwater at intervals, producing large rising bubbles that deform substantially under buoyancy before reaching the free surface. These bubbles vibrate at low frequencies and undergo visible shape and topology changes mid-flight, requiring per-frame frequency updates as the shape evolves. BubbleGym tracks shape evolution and synthesizes characteristic deep, resonant underwater sound. An additional single bubble release example is included in Figure 7.
