Struct TerrainData 

pub struct TerrainData {
    pub name: String,
    pub resolution: u32,
    pub scale: [f32; 3],
    pub heights: Vec<i16>,
    pub holes: Option<Vec<u8>>,

}

A TerrainData as stored.

Fields

name: String

m_Name.

resolution: u32

Samples along each side of the heightmap.

scale: [f32; 3]

Metres between samples along x, the height in metres along y, metres between samples along z (m_Scale).

heights: Vec<i16>

The height samples, row z then column x, each 0 to MAX_HEIGHT.

holes: Option<Vec<u8>>

One byte per cell, 0 a hole; None when none are stored.

layers: Vec<Option<ObjRef>>

The splat layers (m_TerrainLayers), read with TerrainLayerData::read; None for a null pointer.

alphamaps: Vec<Option<ObjRef>>

The splat weight textures (m_AlphaTextures), four layers’ weights each as RGBA.

alphamap_resolution: u32

m_AlphamapResolution: the side of an alphamap in texels.

tree_prototypes: Vec<Option<ObjRef>>

Each tree prototype’s prefab.

trees: Vec<TreeInstance>

The tree instances.

Implementations

impl TerrainData

pub fn read(player: &Player, r: &ObjRef) -> Result<Self>

Read the TerrainData r of player, its heightmap as check_heightmap requires.

pub fn height(&self, x: usize, z: usize) -> Option<f64>

The height of sample (x, z) in metres above the terrain’s position; None when (x, z) is not a sample of the heightmap.

pub fn size(&self) -> [f64; 3]

The terrain’s size in metres: (resolution - 1) * scale along x and z, scale.y high.
