This section contains some tutorials for animating the mjbWorld program using physics. The X3D/VRML nodes are not especially good for physics because the motions need to be predefined with start and end points, so the program has addional node which continue moveing until they interact with other objects.
- kinematics - defines now to apply continous linear or rotational velocty or acceleration.
- inverse kinematics - defines how a position can be reached with a given set of joints, moving a node effects its parent nodes.
- dynamics - forces and collisions.
- particles - simulation liquids, gasses, etc. using lots of particles.
For more information about the the theory involved see the physics section of this site.
