Unigine::ObjectVolumeOmni Class
Interface for object volumeomni handling. See also the UnigineScript analog. 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.
To use this class, include the UnigineObjectVolumeOmni.h file.
Unigine::ObjectVolumeOmni Class
Members
static int type ()
ObjectVolumeOmni type.Return value
ObjectVolumeOmni type identifier.static Ptr< ObjectVolumeOmni > create (const NodePtr & node)
ObjectVolumeOmni constructor.Arguments
- const NodePtr & node - Node smart pointer.
static Ptr< ObjectVolumeOmni > create (const ObjectPtr & object)
ObjectVolumeOmni constructor.Arguments
- const ObjectPtr & object - Object smart pointer.
static Ptr< ObjectVolumeOmni > create (float width, float height, float radius)
ObjectVolumeOmni constructor. The volume omni object is rendered as a flat rectangle and billboards around its edges.Arguments
- float width - Width of the central flat rectangle in units.
- float height - Height of the central flat rectangle in units.
- float radius - Size of billboards in units.
virtual void setSize (float width, float height) const =0
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.
- float height - A new height of the central flat rectangle in units. If a negative value is provided, 0 will be used instead.
virtual float getWidth () const =0
Returns the width of the central flat rectangle.Return value
The width of the central rectangle in units.virtual float getHeight () const =0
Returns the height of the central flat rectangle in units.Return value
The height of the central rectangle in units.virtual void setRadius (float radius) const =0
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.
virtual float getRadius () const =0
Returns the size of billboards.Return value
The size of billboards in units.virtual void setAttenuation (float attenuation) const =0
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.
virtual float getAttenuation () const =0
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.Last update: 03.07.2017
