ACES

ACES tone mapping operator.

This operator is an implementation of the ACES Reference Rendering Transform (RRT) combined with the Output Device Transform (ODT) for sRGB monitors (dim surround, 100 nits).

Constructors

ACES

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").
