Detailed Description
A system that simulates a simple wind model. The wind is described as a uniform worldwide model. So it is independent from model position for simple computations. Its components are computed separately:
- Horizontal amplitude: Low pass filtering on user input (complementary gain)
- small local fluctuations
- noise on value (noise amplitude is a factor of wind magnitude)
- Horizontal direction: Low pass filtering on user input (complementary gain)
- small local fluctuations
- noise on value
- Vertical amplitude: Low pass filtering on user input (complementary gain)
- small local fluctuations
- noise on value
The following parameters are used by the system:
<horizontal><magnitude><time_for_rise>
Analogous to the time constant of the low pass filter.<horizontal><magnitude><sin><amplitude_percent>
Fraction of the filtered wind velocity magnitude that is set to be the amplitude of the sinusoid.<horizontal><magnitude><sin><period>
Period of the sinusoid that is added to the wind velocity magnitude.<horizontal><magnitude><noise>
Parameters for the noise that is added to the wind velocity magnitude.<horizontal><direction><time_for_rise>
Analogous to the time constant of the low pass filter.<horizontal><direction><sin><amplitude>
Amplitude of the sinusoidal that is added on the direction of the wind velocity.<horizontal><direction><sin><period>
Period of the sinusoid that is added to the wind velocity direction.<horizontal><direction><noise>
Parameters for the noise that is added to the wind velocity direction.<vertical><time_for_rise>
Analogous to the time constant of the low pass filter for the vertical wind velocity magnitude.<vertical><noise>
Parameters for the noise that is added to the vertical wind velocity magnitude.
