Elevation samples from a terrain provider are passed to a 2D WebGL renderer. The renderer then applies a combination of the following algorithms: * Colour ramp * Hillshade * Contour lines This imagery provider is a contribution to the Cesium community by [Propeller Aerobotics](https://www.propelleraero.com/) and is licensed under the same license as Cesium (Apache 2.0). **View the [live demo](https://propelleraero.github.io/cesium-elevation-gradient/).** Run the test app with a local server ------------------------------------ ``` npm install npm start ``` Then browse to [http://localhost:8080](http://localhost:8080) Using in your app ----------------- This code uses GLSL shaders. It is currently set up to load them using [shader-loader for webpack](https://github.com/makio64/shader-loader). If you happen to be using webpack on your project then you should be able to... * install shader-loader: ``` npm install shader-loader --save-dev ``` * set it up in your webpack.config.js: ``` module: { loaders: [{ test: /\.(glsl|vs|fs)$/, loaders: ['shader'] }] } ``` * import (or require()) into your app ``` import ElevationGradientImageryProvider from 'cesium-elevation-gradient/lib/ElevationGradientImageryProvider' ```
