SoSFInt32 pulseFrequency
Number of frames to be visualized during an animation cycle.
SoSFInt32 viewFrame
Visualized frame index (used only if isBlinking is FALSE).
SoSFFloat shiftStart
Duration from which the first position on the streamline is calculated.
SoSFFloat blinkSpeed
Number of animation's cycles per second.
SoSFBool isBlinking
Stop the animation if isBlinking is FALSE.
SoSFFloat timeStep
Time step between 2 consecutive points of a streamline.
SoSFBool isStartRandomized
Set it to TRUE prevents each first position of the different streamlines to start simultaneously.
