Properties ¶

globalAlpha ¶

• globalAlpha: number

全局透明度，主要影响粒子拖尾效果，默认 0.9

Inherited from ¶

IOptions.globalAlpha

Defined in ¶

core/dist/index.d.ts:391

lineWidth ¶

• lineWidth: number | emptyFunc

线条宽度

Inherited from ¶

IOptions.lineWidth

Defined in ¶

core/dist/index.d.ts:395

colorScale ¶

• colorScale: string | emptyFunc | string[]

粒子颜色配置, 默认#fff，当为回调函数时，参数 function(m:对应点风速值) => string

Inherited from ¶

IOptions.colorScale

Defined in ¶

core/dist/index.d.ts:399

velocityScale ¶

• velocityScale: number | emptyFunc

对于粒子路径步长的乘积系数，默认 1 / 25

Inherited from ¶

IOptions.velocityScale

Defined in ¶

core/dist/index.d.ts:403

particleAge ¶

• Optional particleAge: number

粒子路径能够生成的最大帧数，默认是 90

Inherited from ¶

IOptions.particleAge

Defined in ¶

core/dist/index.d.ts:407

maxAge ¶

• maxAge: number

粒子路径能够生成的最大帧数，默认是 90；他代表的是我们的 paths 数量的粒子的消亡控制，最小值是 0，最大值是 maxAge，在运行到 age 数时会消失然后进行重启

Inherited from ¶

IOptions.maxAge

Defined in ¶

core/dist/index.d.ts:411

particleMultiplier ¶

• Optional particleMultiplier: number

粒子路径数量的系数，不推荐使用（视野宽度 * 高度 * 系数）

Inherited from ¶

IOptions.particleMultiplier

Defined in ¶

core/dist/index.d.ts:415

paths ¶

• paths: number | emptyFunc

生成的粒子数量

Inherited from ¶

IOptions.paths

Defined in ¶

core/dist/index.d.ts:419

frameRate ¶

• frameRate: number

用户自定义的帧率，默认是 20ms, 大概接近 50fps 帧，我们可能在某些场景需要降低帧率一保证渲染稳定性；注意此配置还会影响粒子运动的速度

Inherited from ¶

IOptions.frameRate

Defined in ¶

core/dist/index.d.ts:423

minVelocity ¶

• Optional minVelocity: number

用户配置的风速最小值，如果未配置会从传入的数据中计算

Inherited from ¶

IOptions.minVelocity

Defined in ¶

core/dist/index.d.ts:427

maxVelocity ¶

• Optional maxVelocity: number

用户配置的风速最大值，如果未配置会从传入的数据中计算

Inherited from ¶

IOptions.maxVelocity

Defined in ¶

core/dist/index.d.ts:431

useCoordsDraw ¶

• Optional useCoordsDraw: boolean

使用外部传入的坐标系统，默认是 true；某些场景下我们可能直接使用像素坐标。

Inherited from ¶

IOptions.useCoordsDraw

Defined in ¶

core/dist/index.d.ts:435

forceRender ¶

• forceRender: boolean

配置是否强制渲染；ol 对图层有一定的优化策略，在地图拖动，缩放等交互会隐藏图层，如果我们期望在拖动缩放也需要保持图层显示，那么可以开启器配置（默认开启）

ol/src/index.ts:22

windOptions ¶

• windOptions: Partial<IOptions>

风场渲染相关配置

Defined in ¶

ol/src/index.ts:27

fieldOptions ¶

• fieldOptions: Partial<IField>

风场数据相关配置
