KBE3D / KBCore / Cesium / CorridorGeometry

类: CorridorGeometry

A description of a corridor. Corridor geometry can be rendered with both Primitive and GroundPrimitive.

示例

const corridor = new Cesium.CorridorGeometry({
  vertexFormat : Cesium.VertexFormat.POSITION_ONLY,
  positions : Cesium.Cartesian3.fromDegreesArray([-72.0, 40.0, -70.0, 35.0]),
  width : 100000
});

参数

Object with the following properties:

参数

An array of positions that define the center of the corridor.

参数

The distance between the edges of the corridor in meters.

参数

The ellipsoid to be used as a reference.

参数

The distance, in radians, between each latitude and longitude. Determines the number of positions in the buffer.

参数

The distance in meters between the ellipsoid surface and the positions.

参数

The distance in meters between the ellipsoid surface and the extruded face.

参数

The vertex attributes to be computed.

参数

Determines the style of the corners.

属性
