WavefieldPlugin

A Gazebo model plugin to simulate water waves.

Usage

Add the SDF for the plugin to the <model> element of your wave model.

Parameters

1. <static> (bool, default: false)
   Create a static wave field if set to true.

2. <update_rate> (double, default: 30.0)
   The rate in Hz at which the wavefield is updated.

3. <size> (Vector2D, default: (1000 1000))
   A two component vector for the size of the wave field in each direction.

4. <cell_count> (int, default: (50 50))
   A two component vector for the number of grid cells in each direction.

5. <number> (int, default: 1)
   The number of component waves.

6. <scale> (double, default: 2.0)
   The scale between the mean and largest / smallest component waves.

7. <angle> (double, default: 2*pi/10)
   The angle between the mean wave direction and the largest / smallest component waves.

8. <steepness> (double, default: 1.0)
   A parameter in [0, 1] controlling the wave steepness with 1 being steepest.

9. <amplitude> (double, default: 0.0)
   The amplitude of the mean wave in [m].

10. <period> (double, default: 1.0)
    The period of the mean wave in [s].

11. <phase> (double, default: 0.0)
    The phase of the mean wave.

12. <direction> (Vector2D, default: (1 0))
    A two component vector specifiying the direction of the mean wave.

13. <wave_patch> (bool, default: false)
    Display a wave patch marker if set to true.

14. <wave_patch_size> (Vector2D, default: (4 4))
    A two component vector for the size of the wave marker (in units of the wave grid).
