Using elementary physical elements (such as masses, springs, contact interactions...) in a 3D space, it allows for the modular design of any type of physical object for visual generation, audio synthesis or haptic interaction purposes - or even all three at the same time !
Examples of applications range from sound synthesis to interactive visual arts, virtual reality, or even multisensory interaction (hearing, seeing & touching) with virtual musical instruments.
Download the tool and head over to the examples to see for yourself! Regarding sound synthesis possibilities of this tool, you might want to investigate emerging non-linear behaviours inherent to 3D mass-interaction models. For instance, listen to the model below, struck lightly (the first one), then hard (the second one) :
