地形図

3D地形図を作成し、地形にデータをドレープし、陰影と照明をカスタマイズします

地形図は、陰影と照明を使用して地形やその他の表面のテクスチャを表します。これらの関数を使用して、グリッドデータから地形図を作成したり、陰影や照明を調整したり、地形を誇張したり、カラーマップを適用したりします。標高マップの上にデータをドレープすることもできます。

Add Light Source to Terrain Map
Add a light source to a terrain map, then set surface reflectance properties.
Surface Relief Shading
A shaded-relief map models illumination over a surface to highlight the texture of the surface.
Colored Surface Shaded Relief
This example shows how to illuminate surface texture over colored elevation data using shaded relief computations.
Relief Mapping with Light Objects
This example shows how to illuminate surface texture over colored elevation data using a light source.

Drape Data on Elevation Maps
You can drape satellite data over a grid of elevations in order to see the topography of the surface.
Drape Geoid Heights over Topography
This example shows how to drape the figure of the Earth, shown as an attribute (color) data grid, on topographic relief.
