Unigine.ObjectVolumeOmni Class

Inherits: Object

This class is used to create a volume omni object. It simulates a visible volume of light emitted from a flat light source.

The volume omni object is rendered as a flat rectangle and billboards around its edges. The rectangle simulates a light emitting surface and billboards create a light volume around it.

ObjectVolumeOmni Class

Properties

float Attenuation#

Attenuation that modulates smooth fading of the volume omni object when the camera looks at it from a side.
set
Sets attenuation that controls how fast the volume omni object fades out when a camera looks at it from a side.
set value - An attenuation factor. If a too small value is provided, 1E-6 will be used instead.

float Radius#

The size of billboards.
set
Sets the width of billboards at the edges.
set value - A new width in units. If a negative value is provided, 0 will be used instead.

float Height#

The height of the central flat rectangle in units.

float Width#

The width of the central flat rectangle.
