Syntax

float ComputeBoundsScreenRadiusSquared
(
    const FVector4 & Origin,
    const float SphereRadius,
    const FSceneView & View
)

Remarks

Computes the screen radius squared of a given sphere bounds in the given view. This is used at runtime instead of ComputeBoundsScreenSize to avoid a square root. It is a wrapper for the version below that does not take a FSceneView reference but parameters directly

Returns

float - The screen size calculated

Parameters

Parameter	Description
Origin	Origin of the bounds in world space
SphereRadius	Radius of the sphere to use to calculate screen coverage
View	The view to calculate the display factor for
