Unigine.ObjectVolumeProj Class
Inherits from: | Object |
This class is used to create a volume projected object that simulates a light beam from a directional light source. It can be animated to create a flow of particles moving to the end of the beam and rotating, if necessary.
Projected volume object is rendered as a number of billboards, where each following billboard is bigger than the previous one.

ObjectVolumeProj Class
Properties
float VolumeRotation#
The angle of billboards rotation. this angle is set for the billboard at the end of the beam. if a positive value is set, the billboards will be rotated clockwise; if a negative value is set, the billboards will be rotated counterclockwise.
float Velocity#
The velocity with which billboards move to the end of the light beam.
float Step#
The distance between neighboring billboards. the step controls how many billboards are used to render the volume projected object. the bigger the step, the less billboards are used to render the object.
float Fov#
The width of the light beam, which is specified as the angle of the beam cone.
float Radius#
The length of the light beam along the z axis in units.
float Size#
The size of the smallest billboard at the beginning of the light beam.
