Asset Examples

Basic

This example file adds a layer to a globe that has a base layer and then replaces one hemisphere of the planet with a single image. Recommended reading for this example is the documentation on the DefaultTileProvider.

-- Download some example images that we can use
local images = asset.resource({
  Name = "Earth Textures",
  Type = "HttpSynchronization",
  Identifier = "earth_textures",
  Version = 3
})

-- Define the TileProvider
local TileProvider = {
  Identifier = "Example",
  Type = "TileProviderByIndex",
  Enabled = true,
  -- The default tile provider that is used for the whole globe
  DefaultTileProvider = {
    Identifier = "Blue_Marble",
    FilePath = images .. "earth_bluemarble.jpg"
  },
  TileProviders = {
    -- We only define one additional tile provider that overwrites the right
    -- hemisphere of the globe
    {
      Index = { X = 0, Y = 0, Level = 2 },
      TileProvider = {
        Identifier = "Blue_Marble_Night",
        FilePath = images .. "earth_night.png"
      }
    }
  }
}

-- Define the scene graph node
local Node = {
  Identifier = "TileProviderByIndex_Example",
  Renderable = {
    Type = "RenderableGlobe",
    Layers = {
      -- The globe has exactly one layer, which is the one we defined above
