getViewTiles ¶
• getViewTiles: (data: any, renderType: RenderType) => TileID[]
获取当前视野内的瓦片
Type declaration ¶
▸ (data, renderType): TileID[]
Parameters ¶
| Name | Type |
|---|---|
data | any |
renderType | RenderType |
Returns ¶
TileID[]
Defined in ¶
gl-core/src/renderer/index.ts:83
getGridTiles ¶
• getGridTiles: (source: SourceType) => TileID[]
这里我们 Mock 一个瓦片图层，用于获取视野内的所有可渲染瓦片，与getViewTiles不同的是 此方法不会限制层级，方便我们在大层级时也能合理采样

| Name | Type |
|---|---|
z | number |
tiles | TileID[] |
Returns ¶
[number, number]
