Filmic

"Filmic" tone mapping operator.

This tone mapper was designed to approximate the aesthetics of the ACES RRT + ODT for Rec.709 and historically Filament's default tone mapping operator. It exists only for backward compatibility purposes and is not otherwise recommended.

Constructors

Filmic

constructor()

Properties

isLDR

val isLDR: Boolean

True if this tone mapper produces LDR output, i.e. never outputs values above 1.0.

isOneDimensional

val isOneDimensional: Boolean

If true, then this function holds that f(x) = vec3(f(x.r), f(x.g), f(x.b)), which lets Filament build its LUT faster.

Functions

open override fun close()

Destroys the native tone mapper. ColorGrading.Builder only uses it during build(), so it can be closed afterwards.

invoke

operator fun invoke(color: FloatArray, out: FloatArray? = null): FloatArray

Maps an open domain (or "scene referred") color value to a display domain (or "display referred") color value. Both are in the Rec.2020 color space, with no transfer function applied ("linear Rec.2020").
