GrassTerrainSource

Remarks

⚠ The textures the terrain renderer already owns, named rather than re-created. A scatter with its own copy of the heightmap would be a second upload of the same megabytes and a second thing to invalidate when a stroke lands.

Fields and properties (11)

• public TextureViewHandle HeightMap

  The composited heights, one texel per sample.

• public TextureViewHandle WeightMap

  The weightmap holding the bound layer.

• public TextureViewHandle HoleMap

  Where the terrain has no surface at all.

• public SamplerHandle HeightSampler

  How the heights are read.

• public SamplerHandle WeightSampler

  And the weights.

• public SamplerHandle HoleSampler

  And the holes — clamped, unfiltered, at level 0.

• public int WeightChannel

  Which of the weightmap's four channels the layer is.

• public Vector2 HeightMapSize

  How many samples the heightmap is.

• public Vector2 HeightRange

  What a stored height of 0 and 1 mean, in metres.

• public float MetresPerQuad

  How far apart two samples are.

• public Vector3 Origin

  Where the terrain's low corner is, in world space.
