Unigine::ObjectVolumeOmni Class
| Header: | #include <UnigineObjects.h> |
| 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.

static ObjectVolumeOmniPtr create ( float width, float height, float radius ) #
Constructor. Creates a new volume omni object with given properties.Arguments
- float width - Width of the central rectangle in units.
- float height - Height of the central rectangle in units.
- float radius - Size of billboards in units.
void setAttenuation ( float attenuation ) #
Sets attenuation that controls how fast the volume omni object fades out when a camera looks at it from a side.Arguments
- float attenuation - Attenuation factor. If a too small value is provided, 1E-6 will be used instead.
float getAttenuation ( ) const#
Returns attenuation that modulates smooth fading of the volume omni object when the camera looks at it from a side.Return value
The current attenuation factor.float getHeight ( ) const#
Returns the height of the central flat rectangle in units.Return value
The height of the central rectangle in units.void setRadius ( float radius ) #
Sets the width of billboards at the edges.Arguments
- float radius - A new width in units. If a negative value is provided, 0 will be used instead.
float getRadius ( ) const#
Returns the size of billboards.Return value
The size of billboards in units.void setSize ( float width, float height ) #
Sets new dimensions of the volume omni object.Arguments
- float width - A new width of the central flat rectangle in units. If a negative value is provided, 0 will be used instead.
