float ComputeBoundsScreenSize
(
const FVector4 & BoundsOrigin,
const float SphereRadius,
const FVector4 & ViewOrigin,
const FMatrix & ProjMatrix
)
Remarks
Computes the screen size of a given sphere bounds in the given view. The screen size is the projected diameter of the bounding sphere of the model. i.e. 0.5 means half the screen's maximum dimension. float - The screen size calculated
Parameters
| Name | Description |
|---|---|
| BoundsOrigin | Origin of the bounds in world space |
| SphereRadius | Radius of the sphere to use to calculate screen coverage |
| ViewOrigin | The origin of the view to calculate the display factor for |
| ProjMatrix | The projection matrix used to scale screen size bounds |
