Additional Inherited Members | |
| Public Types inherited from SimTK::Motion | |
| enum | Level { NoLevel = -1 , Acceleration = 0 , Velocity = 1 , Position = 2 } |

Detailed Description

Create a sinusoidal prescribed motion applied at position, velocity, or acceleration level.
- Parameters
-
[in,out] mobod The MobilizedBody to which this Motion should be added. [in] level The Motion level that is being prescribed: Motion::Position, Motion::Velocity, or Motion::Acceleration. [in] amplitude Scaling factor mapping the -1..1 sin() result to your desired units; output values will range between -amplitude and +amplitude. [in] rate Angular rate in radians/unit time; e.g. if time is in seconds then rate=2*Pi would be 1 Hz (1 rotation per second). [in] phase Phase angle in radians.
◆ Sinusoid() [2/2]

Default constructor creates an empty handle that can be assigned to reference any Motion::Sinusoid object.
