Class GradientMapModeColorizer

Namespace

Map.MapModes.Colorization

Assembly

MapAssembly.dll

ENGINE: Default map mode colorizer using 3-color gradient interpolation.

Algorithm:

• Sample gradient at 3 points (low=0, mid=0.5, high=1.0)
• GPU compute shader interpolates based on province values
• Provinces with negative values use ocean color

This is the ENGINE default colorizer - wraps existing GradientMapMode.compute logic. GAME layer can register alternatives (DiscreteColorBands, MultiGradient, etc.)
