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 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.
• float height - A new height of the central flat rectangle in units. If a negative value is provided, 0 will be used instead.

Return value

The height of the central rectangle in units.

float getWidth ()

Returns the width of the central flat rectangle.

Return value

The width of the central rectangle 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 getRadius ()
