PlanarWorld
Planar world coordinate system + gravity field + default animation definition
Library
PlanarMechanics
Description
Model PlanarWorld defines all possible general parameters to make parameterization of models much more convenient. It has the following functionalites.
- It defines the global coordinate system fixed in ground and shows the x, y, z axes in animation if wanted.
- It contains all default parameters for animation, e.g. axis diameter, default joint length etc, which can still be overwritten by setting parameters in these models.
- It provides the default gravity definition and its animation.
The pure planar world cannot be coupled to the 3D world. It shall be used when no outer 3D world is available.
