Fisio SB is the Soft Bodies Physics Simulation AddOn for Fisio, the Physics Simulator.

Not for Apple Silicone or MacOs 12.7 and lower

The main features of Fisio SB are:

• Soft or deformable bodies are those that get deformed under the action of forces.
• Any close-geometry prop or figure can participate in the simulation as a soft or deformable body.
• There is no limit to the number of bodies in simulation, other than the computer's memory.
• The bodies can be subjected to animatable gravity and pressure points, and also to damping, point, directional, torque, oscillatory, or wind-type forces.
• Soft bodies can interact with rigid bodies.
• The motion of the soft bodies can be constrained by using links between them or with rigid bodies.
• Like in the natural world, a body can be defined by its material and its shape.
• The physical material nodes are the same as the ones in the Fisio core plugins, with some more properties exposed.
• It can simulate four models of deformable bodies:
  a) Springs: The most common; it works as a spring network. Useful for tissues, sheets, or hollow bodies.
  b) Shell: It can simulate a great variety of body types but is the most appropriate for hollow bodies.
  c) Cable: It works with rigged nodes to simulate cables and wires.
  d) Tetrahedra: This is more appropriate for solid bodies.
