Interface ITerrainRenderer

Namespace

Map.Rendering.Terrain

Assembly

MapAssembly.dll

ENGINE: Interface for pluggable terrain rendering implementations.

ENGINE provides default Imperator Rome-style 4-channel blend map generation. GAME can register custom implementations for different terrain styles:

• Different blending algorithms (8-channel, height-based, etc.)
• Stylized terrain rendering
• Performance-optimized variants

Pattern 20: Pluggable Implementation (Interface + Registry)

public interface ITerrainRenderer
