|
|
=====================
|
||
|
|
Visualization module for vector fields.
|

|
|
# Example
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var createScene = require('gl-plot3d')
|
||
|
|
var createMesh = require('gl-mesh3d')
|
||
|
|
var createStreamTube = require('gl-streamtube3d')
|
||
|
|
var wind = require('dataset-wind')
|
||
|
|
|
||
|
|
var scene = createScene()
|
||
|
|
|
||
|
|
var bounds = [];
|
||
|
|
|
||
|
|
var streamTube = createStreamTube({
|
||
|
|
startingPositions: positionsArray,
|
||
|
|
maxLength: 1000,
|
||
|
|
getVelocity: velocityFunction,
|
||
|
|
colormap: 'portland'
|
||
|
|
}, bounds)
|
||
|
|
|
||
|
|
var mesh = createMesh(gl, streamTube)
|
||
|
|
|
||
|
|
scene.add(mesh)
|
||
|
|
```

## Constructor
|
||
|
|
|
||
|
|
#### `var streamTube = require('gl-streamtube3d')(params, bounds)`
|
||
|
|
Creates a stream tube plot of a vector field.
|
||
|
|
|
||
|
|
* `params` is an object that has the following properties:
|
||
|
|
|
||
|
|
+ `startingPositions` *(Required)* An array of starting positions for the vector field, encoded as arrays.
|
||
|
|
+ `getVelocity(point)` *(Optional)* A getter function to get the velocity at a given point.
|
||
|
|
+ `getDivergence(point)` *(Optional)* A getter function to get the divergence at a given point. Used for the width of the streamtube. Defaults to the divergence of the getVelocity function.
|
||
|
|
+ `maxLength` *(Optional)* The maximum number of segments to add to a streamtube. Default is 1000.
|
||
|
|
+ `tubeSize` *(Optional)* The scaling factor for the streamtubes. The default is 1, which avoids two max divergence tubes from touching at adjacent starting positions.
|
||
|
|
+ `absoluteTubeSize` *(Optional)* Absolute scaling factor for the streamtubes. A value of 1 scales divergence of 1 to 1 coordinate system unit. Overrides tubeSize.
|
||
|
|
+ `colormap` *(Optional)* The colormap to use.
|
||
|
|
|
||
|
|
**Returns** A streamtube plot object that can be passed to gl-mesh3d.
