       MyLinearSineSourcePrms

Objects define linear spatial trajectory (sinusoidal time-frequency) for a particle-source-disturbance.

Instance Methods

__init__(self, posn, startTime=0.5, freq=0.02, magnitude=[0,0.10,0])
Initialises trajectory parameters.

Vec3

getPosn(self, t)
Returns the position of the disturbance at the specified time.

Method Details

Initialises trajectory parameters.

Parameters:

posn (Vec3) - The approx location of the source-disturbance.
startTime (float) - The time at which the disturbance begins.
freq (float) - The: frequency of the sinusoidal disturbance.
magnitude (Vec3) - The direction and maximum displacement of the source.

Returns the position of the disturbance at the specified time.

Parameters:

Returns: Vec3

Position of disturbance at time t.
