Detailed Description

Defines a Terrain that is capable of rendering large landscapes from 2D heightmap images.

Terrains can be constructed from several different internal formats heightmap sources:

  1. RGB888
  2. RGBA8888
  3. Luminance(gray-scale)8

Terrain use TerrainData struct to initialize.the TerrainData struct warp all parameters that Terrain initialization need. TerrainData provide several handy constructor for users

Surface detail is provided via texture splatting, where multiple Detail texture layers can be added along with alpha map to define how different Detail texture blend with each other. These DetailTexture can be defined in TerrainData. The number of supported Detail texture is Four. although typically 2-3 levels is sufficient. For simple usage ,surface detail also is provided via simple Texture.

Internally, Terrain is divide into smaller, more manageable chunks, which can be culled separately for more efficient rendering. The size of the terrain chunks can be controlled via the chunkSize property in TerrainData.

Chunks are managed under the QuadTree.As DE FACTO terminal Node of the QuadTree; let us cull chunks efficientlly to reduce drawCall amount And reduce the VBOs'Size that pass to the GPU.

Level of detail (LOD) is supported using a technique that is similar to texture mipmapping – called GeoMapping. A distance-to-camera based test used to decide the appropriate LOD for a terrain chunk. The number of LOD levels is 0 by default (which means only the base level is used),the maxium number of LOD levels is 4. Of course ,you can hack the value individually.

Finally, when LOD is enabled, cracks can begin to appear between terrain Chunks of different LOD levels. An acceptable solution might be to simply reduce the lower LOD(high detail,smooth) chunks border, And let the higher LOD(rough) chunks to seamlessly connect it.

We can use ray-terrain intersection to pick a point of the terrain; Also we can get an arbitrary point of the terrain's height and normal vector for convenience .

set directional light for the terrain The direction of directional light, Note that lightDir is in the terrain's local space.

Most of the time terrain is placed at (0,0,0) and without rotation, so lightDir is also in the world space.

local setLightDir ( local  lightDir)
