CubeLut

class CubeLut(source)

A 3D colour table parsed from a .cube file, which every backend draws through trilinear interpolation.

The table maps SDR codes to SDR codes over a domain of 0f to 1f. Entries are held in .cube order, with red changing fastest and blue slowest. Two tables with the same entries are equal, and hashCode is worked out once, so comparing tables per frame does not walk their entries.

Properties

val isIdentity: Boolean

Whether this table leaves every code where it is, within what its 16 bit atlas can tell apart.

How many grid points the table has along each axis.

Functions

fun at(red: Float, green: Float, blue: Float): FloatArray

The colour this table maps a red, green and blue code to, in 0f..1f and read between grid points trilinearly.
