Detailed Description

A sector-shaped particle placer.

This placer sets the initial position of incoming particle by choosing a random position within a circular sector; this sector is defined by three parameters: a center point, which is inherited directly from osgParticle::CenteredPlacer, a range of values for radius, and a range of values for the central angle (sometimes called phi).
