Terrain

OmegaEngine supports heightmap-based terrain rendering with multiple blended surface textures and pre-calculated self-shadowing.

The Terrain class renders heightmap-based terrains. The terrain is divided into blocks for efficient culling and rendering.

AlphaFramework.World.Terrains provides tools for terrain generation, editing, and storage.

Coordinates

Terrain data uses a 2D coordinate system for heightmap and texture data. This coordinate system is directed right-downwards (as used in graphics files).

These 2D coordinates map to the 3D engine coordinate system:

Axis	Terrain Dimension
Positive X axis	Width of the terrain
Positive Y axis	Height of the terrain
Negative Z axis	Depth of the terrain
