Usage

With presets

    const terrain = new WHS.Terrain({
      geometry: {
        map: 'assets/terrain/default_terrain.png', // Heightmap image.
        depth: 100, // Difference between min z and max z.
        width: 256, // Terrain x resolution
        height: 256 // Terrain y resolution
      },

      mass: 0, // Make it static.

      physics: {
        friction: 1,
        restitution: 0
      },

      material: ['default', // Use preset.
        [ // Array of textures for preset.
          WHS.texture('assets/textures/terrain/dirt-512.jpg'),
          WHS.texture('assets/textures/terrain/sand-512.jpg'),
          WHS.texture('assets/textures/terrain/grass-512.jpg'),
          WHS.texture('assets/textures/terrain/rock-512.jpg'),
          WHS.texture('assets/textures/terrain/snow-512.jpg')
        ]
      ]
    });

Custom

    const terrain = new WHS.Terrain({
      geometry: {
        map: 'assets/terrain/default_terrain.png', // Heightmap image.
        depth: 100, // Difference between min z and max z.
        width: 256, // Terrain x resolution
        height: 256 // Terrain y resolution
      },

      mass: 0, // Make it static.

      physics: {
        friction: 1,
        restitution: 0
      },

      material: [
        {
          from: [0.1, 0.25],
          to: [0.24, 0.26],
          scale: 10.0,
          texture: WHS.texture('assets/textures/terrain/dirt-512.jpg')
        },
        {
          from: [0.24, 0.27],
          to: [0.28, 0.31],
          scale: 10.0,
          texture: WHS.texture('assets/textures/terrain/sand-512.jpg')
        },
        {
          from: [0.28, 0.32],
          to: [0.35, 0.40],
          scale: 20.0,
          texture: WHS.texture('assets/textures/terrain/grass-512.jpg')
        },
        {
          from: [0.30, 0.40],
          to: [0.40, 0.70],
          scale: 20.0,
          texture: WHS.texture('assets/textures/terrain/rock-512.jpg')
        },
        {
          from: [0.42, 0.45],
          scale: 10.0,
          texture: WHS.texture('assets/textures/terrain/snow-512.jpg')
        }
      ]
    });

• from - Gradient start (applied texture).
• to - Gradient end (applied texture).
• scale - Texture scale.
• texture - THREE.Texture object.

Heightmap example

• Should be grayscale. (black <-> white).
• Resolution should be a power of two (256x256, 512x512, 1024x1024 ...)
