Hello, Bullet Users!
I try to understand physical basics of Bullet Library and here there are some questions.
Can I use this Library within the bounds of Discrete Element Method? Specifically:
1) Which type of contact model is used in this library while simulating of impacts of bodies (elastic contact by Hertz or Hooke's law; viscous-elastic, etc.)?
2) How can I change the physical properties of colliding bodies (Poisson ratio, coefficient of elasticity, cohesion)?
Thankful in advance.
