The nodes may either derive from the edges of a two-dimensional polygonal mesh representation of the surface of the object, or from a three-dimensional network of nodes and edges modeling the internal structure of the object (or even a one-dimensional system of links, if for example a rope or hair strand is being simulated). In this approach, the body is modeled as a set of point masses (nodes) connected by ideal weightless elastic springs obeying some variant of Hooke's law. Two nodes as mass points connected by a parallel circuit of a spring and a damper. Several physics engines currently provide software for soft-body simulation. Generally, these methods only provide visually plausible emulations rather than accurate scientific/engineering simulations, though there is some crossover with scientific methods, particularly in the case of finite element simulations. The scope of soft body dynamics is quite broad, including simulation of soft organic materials such as muscle, fat, hair and vegetation, as well as other deformable materials such as clothing and fabric.
While the relative distances of points are not fixed, the body is expected to retain its shape to some degree (unlike a fluid). Unlike in simulation of rigid bodies, the shape of soft bodies can change, meaning that the relative distance of two points on the object is not fixed. The applications are mostly in video games and films. Soft-body dynamics is a field of computer graphics that focuses on visually realistic physical simulations of the motion and properties of deformable objects (or soft bodies). Together with our diverse set of levels, these properties make BeamNG.tech the ideal platform to develop ADAS as well as highly realistic driver’s training applications.Short description: Computer graphics simulation of deformable objects The modding system allows anyone to customize various components of the simulation, be it the vehicle models, assets, scenarios, or the user interaction. The soft-body physics approach allows to faithfully simulate the kinematic properties of our vehicle models and leads to a realistic replication of their driving behavior. BeamNG.tech stands out among the several available driving platforms through its custom soft-body physics engine, detailed modeling of the vehicle subsystems, and high degree of adaptability. ADAS researchers and developers use BeamNG.tech as a platform for model-in-the-loop testing and development. Driver’s training applications are supported by an immersive simulation environment that can easily be adapted by the distributor to match the desired user interface and vehicle type.
Simulation platforms are critical components for the evaluation and development of driver’s training applications and intelligent algorithms for advanced driver-assistance systems (ADAS).
