Step is based on bodies and forces placed by the user: •
Bodies range from tiny particles to huge polygons, and each body has unique properties that influence the outcome of the
simulation, such as
mass and
velocity, and their derivations such as
kinetic energy. •
Forces can be either placed directly by the user or produced by adding
gravitation,
Coulomb force or other effects. The program also features
springs and
soft bodies. Step allows reverting after simulation, so the user can modify the bodies and forces and see how the outcome of the simulation is affected. All the bodies and forces can also be modified in real time. The software allows users to add graphs and meters and configure them to any property of any body. This allows, for example, graphing speed or acceleration against time. ==References==
