Color

Utilities to manipulate and convert colors. RGB colors are 3 floats, RGBA colors 4; results are new arrays. sRGB conversions are the accurate ones (C++'s default ColorConversion::ACCURATE).

Functions

absorptionAtDistance

fun absorptionAtDistance(color: FloatArray, distance: Float): FloatArray

Computes the Beer-Lambert absorption coefficients that turn white light into color at distance, for the absorption parameter of materials that use refraction.

cct

fun cct(K: Float): FloatArray

Converts a correlated color temperature, in kelvin within 1,000K..15,000K, to a linear sRGB color.

illuminantD

fun illuminantD(K: Float): FloatArray

Converts a CIE standard illuminant series D, in kelvin within 4,000K..25,000K, to a linear sRGB color.

toLinear

fun toLinear(color: FloatArray): FloatArray

Converts an sRGB color, RGB or RGBA (alpha left unmodified), to linear space.

fun toLinear(type: RgbType, color: FloatArray): FloatArray

Converts an RGB color to linear space; the conversion depends on type.

fun toLinear(type: RgbaType, color: FloatArray): FloatArray

Converts an RGBA color to linear space; the conversion depends on type.

toSRGB

fun toSRGB(color: FloatArray): FloatArray

Converts a linear color, RGB or RGBA (alpha left unmodified), to sRGB space.
