	distance As Single
) As Single

public:
static float GetExtent(
	float fieldOfView, 
	float distance
)

static member GetExtent : 
        fieldOfView : float32 * 
        distance : float32 -> float32

Parameters

fieldOfView: Type: SystemSingle
The field of view in radians.
distance: Type: SystemSingle
The distance at which the extent is calculated.

Return Value

Type: Single
The extent of the view volume at the given distance.
