Terrain data for a single tile where the terrain data is represented as a heightmap. A heightmap is a rectangular array of heights in row-major order from south to north and west to east.
alias HeightmapTerrainData
- The options object takes the following properties - {TypedArray} options.buffer The buffer containing height data. - {Number} options.width The width (longitude direction) of the heightmap, in samples. - {Number} options.height The height (latitude direction) of the heightmap, in samples. - {Number} [options.childTileMask=15] A bit mask indicating which of this tile's four children exist. If a child's bit is set, geometry will be requested for that tile as well when it is needed. If the bit is cleared, the child tile is not requested and geometry is instead upsampled from the parent. The bit values are as follows:
height = buffer[index] + buffer[index + 1] * 256 + buffer[index + 2] * 256 * 256 + buffer[index + 3] * 256 * 256 * 256This is assuming that the isBigEndian property is false. If it is true, the order of the elements is reversed. - {Boolean} [options.structure.isBigEndian=false] Indicates endianness of the elements in the buffer when the stride property is greater than 1. If this property is false, the first element is the low-order element. If it is true, the first element is the high-order element. - {Boolean} [options.createdByUpsampling=false] True if this instance was created by upsampling another instance; otherwise, false.var buffer = ... var heightBuffer = new Uint16Array(buffer, 0, that._heightmapWidth * that._heightmapWidth); var childTileMask = new Uint8Array(buffer, heightBuffer.byteLength, 1)[0]; var waterMask = new Uint8Array(buffer, heightBuffer.byteLength + 1, buffer.byteLength - heightBuffer.byteLength - 1); var terrainData = new Cesium.HeightmapTerrainData({ buffer : heightBuffer, width : 65, height : 65, childTileMask : childTileMask, waterMask : waterMask });
