<h2>Import</h2>
|
|
|
|
<p>
|
|
[name] is an add-on, and therefore must be imported explicitly.
|
|
See [link:#manual/introduction/Installation Installation / Addons].
|
|
</p>
|
|
|
|
<code>
|
|
import { LineSegmentsGeometry } from 'three/addons/lines/LineSegmentsGeometry.js';
|
|
</code>
|
|
|
|
<h2>Example</h2>
|
|
|
|
<p>[example:webgl_lines_fat_raycasting WebGL / lines / fat / raycasting ]</p>
|
|
|
|
<h2>Constructor</h2>
|
|
|
|
<h3>[name]()</h3>
|
|
<p>
|
|
Creates a new geometry.
|
|
Call [page:LineSegmentsGeometry.setPositions setPositions] to add segments.
|
|
</p>
|
|
|
|
<h2>Properties</h2>
|
|
<p>See the base [page:InstancedBufferGeometry] class for common properties.</p>
|
|
|
|
<h3>[property:Boolean isLineSegmentsGeometry]</h3>
|
|
<p>Read-only flag to check if a given object is of type [name].</p>
|
|
|
|
<h2>Methods</h2>
|
|
<p>See the base [page:Mesh] class for common methods.</p>
|
|
|
|
<h3>[method:this fromEdgesGeometry]( [param:EdgesGeometry geometry] )</h3>
|
|
<p>
|
|
Copy the vertex positions of an edge geometry into this geometry.
|
|
</p>
|
|
|
|
<h3>[method:this fromLineSegments]( [param:LineSegments lineSegments] )</h3>
|
|
<p>
|
|
Copy the vertex positions of a [page:LineSegments] object into this geometry.
|
|
Assumes the source geometry is not using indices.
|
|
</p>
|
|
|
|
<h3>[method:this fromMesh]( [param:Mesh mesh] )</h3>
|
|
<p>
|
|
Copy the vertex positions of a mesh object into this geometry.
|
|
</p>
|
|
|
|
<h3>[method:this fromWireframeGeometry]( [param:WireframeGeometry geometry] )</h3>
|
|
<p>
|
|
Copy the vertex positions of a wireframe geometry into this geometry.
|
|
</p>
|
|
|
|
<h3>[method:this setColors]( [param:Array array] )</h3>
|
|
<p>
|
|
Replace the per-vertex colors.
|
|
Every sixtuple describes a segment: `[r1, g1, b1, r2, g2, b2]`.
|
|
The array can be an `Array` or `Float32Array`.
|
|
</p>
|
|
|
|
<h3>[method:this setPositions]( [param:Array array] )</h3>
|
|
<p>
|
|
Replace the vertex positions with a new set.
|
|
The array can be an `Array` or `Float32Array`.
|
|
The length must be a multiple of six.
|
|
</p>
|
|
<p>
|
|
See also [page:LineSegmentsGeometry.positions positions].
|
|
</p>
|
|
|
|
<h3>[method:undefined toJSON]()</h3>
|
|
<p>
|
|
Unimplemented.
|
|
