Constructors
constructor
Instantiates HDR filter for reflection maps
Parameters
engine: ThinEngine
Thin engine
Optional options: IHDRFilteringOptions
Options
Returns HDRFiltering
Properties
hdr
Scales pixel intensity for the input HDR map.
qualitySearch playground for quality
Quality switch for prefiltering. Should be set to Constants.TEXTURE_FILTERING_QUALITY_OFFLINE unless
you care about baking speed.
Methods
is
Get a value indicating if the filter is ready to be used
Parameters
texture: BaseTexture
Texture to filter
Returns boolean
true if the filter is ready
prefilterSearch playground for prefilter
Prefilters a cube texture to have mipmap levels representing roughness values. Prefiltering will be invoked at the end of next rendering pass. This has to be done once the map is loaded, and has not been prefiltered by a third party software. See http://blog.selfshadow.com/publications/s2013-shading-course/karis/s2013_pbs_epic_notes_v2.pdf for more information
Parameters
texture: BaseTexture
Texture to filter
Optional onFinished: Nullable<(() => void)>
Callback when filtering is done
Returns Promise<void>
Promise called when prefiltering is done
Filters HDR maps to get correct renderings of PBR reflections
