StreamLineBuilder
An object that assists in building StreamLine objects.
new StreamLineBuilder(viewer)
Constructs an instance of StreamLineBuilder object. For proper resource management
it is recommended to obtain a StreamLineBuilder through DataVisualization class.
Parameters
| viewer* Viewer3D | The instance a Viewer3D to associate this object with. |
* Required
Examples
const dataVizExtn = await viewer.loadExtension("Autodesk.DataVisualization");
const streamLineBuilder = dataVizExtn.streamLineBuilder;
Methods
dispose()
Dispose of all the underlying StreamLine objects that are associated with this
StreamLineBuilder object. This also releases their corresponding material and
geometrical data.
createStreamLine(streamLineSpecs)
Creates StreamLine objects using the StreamLineSpecs and associates them with the
StreamLineBuilder object.
Parameters
| streamLineSpecs* | See StreamLineSpecs for more details. |
* Required
Returns
| type | description |
|---|---|
| StreamLine |
Examples
const points = [ 10, 10, 10, 20, 20, 20, ... ];
const streamLineData = {
points: new Float32Array(points),
};
const streamLineSpecs = {
lineWidth: 8.0,
lineColor: new THREE.Color(0xff0080),
opacity: 1.0,
lineData: streamLineData,
};
const streamLineBuilder = dataVizExtension.streamLineBuilder;
const streamLine = streamLineBuilder.createStreamLine(streamLineSpecs);
