Pressure vs. volume growth actuation

This example illustrates the difference between pressure and volume growth actuation. Pressure based actuation represents an actuation performed by compressing a gas (air). Volume based actuation represents an actuation performed by an incompressible medium (water, oil).

FYI: If the computation is slow, it might be because you did not add sparse and metis to sofa configuration.

The scene simulate a pressure on a cavity in the bunny body. You can either control the volume growth (right) or the pressure (left). It uses the SurfacePressureConstraint component, available in the SoftRobots plugin Further descriptions of the component can be found at: https://project.inria.fr/softrobot/documentation/
