Detailed Description

Predefined controller function based on a waveform.

Remarks:
A waveform function translates parametric input to parametric output based on a wave. The factors affecting the function are:
Note that for simplicity of integration with the rest of the controller insfrastructure, the output of the wave is parametric i.e. 0..1, rather than the typical wave output of [-1,1]. To compensate for this, the traditional output of the wave is scaled by the following function before output:
output = (waveoutput + 1) * 0.5
Hence a wave output of -1 becomes 0, a wave ouput of 1 becomes 1, and a wave output of 0 becomes 0.5.

Constructor & Destructor Documentation

Ogre::WaveformControllerFunction::WaveformControllerFunction ( WaveformType  wType,
Real  base = 0,
Real  frequency = 1,
Real  phase = 0,
Real  amplitude = 1,
bool  deltaInput = true,
Real  dutyCycle = 0.5 
)

Default constructor, requires at least a wave type, other parameters can be defaulted unless required.

Parameters:
deltaInput If true, signifies that the input will be a delta value such that the function should add it to an internal counter before calculating the output.
dutyCycle Used in PWM mode to specify the pulse width.
