EnvironmentalHdrParameters (sceneform 2.0.3 API)

java.lang.Object
- pro.streem.ar.sceneform.utilities.EnvironmentalHdrParameters

```
public class EnvironmentalHdrParameters
extends java.lang.Object
```
Provides scaling factors from Environmental Hdr to Filament.
A conversion is required to convert between Environmental Hdr units and an intensity value Filament can use.
