KBE3D / KBCore / Cesium / VoxelCell

类: VoxelCell

A cell from a VoxelPrimitive. <p> Provides access to properties associated with one cell of a voxel primitive. </p> <p> Do not construct this directly. Access it through picking using Scene#pickVoxel. </p>

示例

// On left click, display all the properties for a voxel cell in the console log.
handler.setInputAction(function(movement) {
  const voxelCell = scene.pickVoxel(movement.position);
  if (voxelCell instanceof Cesium.VoxelCell) {
    const propertyIds = voxelCell.getPropertyIds();
    const length = propertyIds.length;
    for (let i = 0; i < length; ++i) {
      const propertyId = propertyIds[i];
      console.log(`{propertyId}: ${voxelCell.getProperty(propertyId)}`);
    }
  }
}, Cesium.ScreenSpaceEventType.LEFT_CLICK);

参数

The voxel primitive containing the cell

参数

The index of the tile

参数

The index of the sample within the tile, containing metadata for this cell

属性

primitive

readonly primitive: VoxelPrimitive

All objects returned by Scene#pick have a <code>primitive</code> property. This returns the VoxelPrimitive containing the cell.

---

sampleIndex

readonly sampleIndex: number

Get the sample index of the cell.

---

tileIndex

readonly tileIndex: number

Get the index of the tile containing the cell.

---

orientedBoundingBox

readonly orientedBoundingBox: OrientedBoundingBox

Get a copy of the oriented bounding box containing the cell.

方法

hasProperty()

hasProperty(name: string): boolean

Returns <code>true</code> if the feature contains this property.

参数

name

string

The case-sensitive name of the property.

返回

boolean

Whether the feature contains this property.

---

getNames()

getNames(): string[]

Returns an array of metadata property names for the feature.

返回

string[]

The IDs of the feature's properties.

---

getProperty()

getProperty(name: string): any

Returns a copy of the value of the metadata in the cell with the given name.

参数

name

string

The case-sensitive name of the property.

返回

any

The value of the property or undefined if the feature does not have this property.

示例

// Display all the properties for a voxel cell in the console log.
const names = voxelCell.getNames();
for (let i = 0; i < names.length; ++i) {
  const name = names[i];
  console.log(`{name}: ${voxelCell.getProperty(name)}`);
}
