ACESLegacy

ACES tone mapping operator, modified for legacy compatibility.

This operator is the same as ACES but applies a brightness multiplier of ~1.6 to the input color value to target brighter viewing environments. Exists for backward compatibility purposes.

Constructors

ACESLegacy

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").
