TerrainMesh

new TerrainMesh(center, vertices, indices, minimumHeight, maximumHeight, boundingSphere3D, occludeePointInScaledSpace, vertexStride)

A mesh plus related metadata for a single tile of terrain. Instances of this type are usually created from raw TerrainData.
Name Type Default Description
center Cartesian3 The center of the tile. Vertex positions are specified relative to this center.
vertices Float32Array The vertex data, including positions, texture coordinates, and heights. The vertex data is in the order [X, Y, Z, H, U, V], where X, Y, and Z represent the Cartesian position of the vertex, H is the height above the ellipsoid, and U and V are the texture coordinates.
indices Uint16Array | Uint32Array The indices describing how the vertices are connected to form triangles.
minimumHeight Number The lowest height in the tile, in meters above the ellipsoid.
maximumHeight Number The highest height in the tile, in meters above the ellipsoid.
boundingSphere3D BoundingSphere A bounding sphere that completely contains the tile.
occludeePointInScaledSpace Cartesian3 The occludee point of the tile, represented in ellipsoid- scaled space, and used for horizon culling. If this point is below the horizon, the tile is considered to be entirely below the horizon.
vertexStride Number 6 optional The number of components in each vertex.

center :Cartesian3

The center of the tile. Vertex positions are specified relative to this center.
Source: Core/TerrainMesh.js, line 34

indices :Uint16Array|Uint32Array

The indices describing how the vertices are connected to form triangles.

maximumHeight :Number

The highest height in the tile, in meters above the ellipsoid.
Source: Core/TerrainMesh.js, line 70

minimumHeight :Number

The lowest height in the tile, in meters above the ellipsoid.
Source: Core/TerrainMesh.js, line 64

occludeePointInScaledSpace :Cartesian3

The occludee point of the tile, represented in ellipsoid- scaled space, and used for horizon culling. If this point is below the horizon, the tile is considered to be entirely below the horizon.

stride :Number

The number of components in each vertex. Typically this is 6 for the 6 components [X, Y, Z, H, U, V], but if each vertex has additional data (such as a vertex normal), this value may be higher.

vertices :Float32Array

The vertex data, including positions, texture coordinates, and heights. The vertex data is in the order [X, Y, Z, H, U, V], where X, Y, and Z represent the Cartesian position of the vertex, H is the height above the ellipsoid, and U and V are the texture coordinates. The vertex data may have additional attributes after those mentioned above when the TerrainMesh#stride is greater than 6.
