float ComputeBoundsScreenRadiusSquared
(
const FVector4 & BoundsOrigin,
const float SphereRadius,
const FVector4 & ViewOrigin,
const FMatrix & ProjMatrix
)
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. float - The screen size calculated
Parameters
| Name | Description |
|---|---|
| Origin | Origin of the bounds in world space |
| SphereRadius | Radius of the sphere to use to calculate screen coverage |
| ViewOrigin | The view origin involved in the calculation |
| ProjMatrix | The projection matrix of the view involved in the calculation |
