|
* @param {Property} [options.positions] A Property specifying the array of {@link Cartesian3} positions which define the top of the wall.
|
* @param {Property} [options.minimumHeights] A Property specifying an array of heights to be used for the bottom of the wall instead of the globe surface.
|
* @param {Property} [options.maximumHeights] A Property specifying an array of heights to be used for the top of the wall instead of the height of each position.
|
* @param {Property} [options.granularity=Cesium.Math.RADIANS_PER_DEGREE] A numeric Property specifying the angular distance between each latitude and longitude point.
|
* @param {Property} [options.fill=true] A boolean Property specifying whether the wall is filled with the provided material.
