Class DefaultTerrainRenderer

Namespace

Map.Rendering.Terrain

Assembly

MapAssembly.dll

ENGINE: Default terrain renderer using Imperator Rome-style 4-channel blending.

Features:

• GPU-accelerated blend map generation via compute shader
• Configurable sample radius (5x5 default) for terrain transition width
• Configurable blend sharpness (1.0 = linear, >1 = sharper transitions)
• Outputs DetailIndexTexture (4 terrain indices) + DetailMaskTexture (4 blend weights)

Pattern 20: Pluggable Implementation (Interface + Registry)
