示例1: updateTerrain
/** If necessary defines a new particle type for the terrain emitter. Then
* adjusts the location of the terrain emitter to be in synch with the
* current wheel position, and defines the emission rate depending on speed,
* steering, and skidding.
* \param pk Particle type to use.
