		<h1>[name]</h1>

		<p class="desc">
			A chain of vertices, forming a polyline.
		</p>

		<p class="desc">
			This is used in [page:Line2] to describe the shape.
		</p>

		<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 { LineGeometry } from 'three/addons/lines/LineGeometry.js';
		</code>

		<h2>Examples</h2>

		<p>
			[example:webgl_lines_fat WebGL / lines / fat ]<br />
			[example:webgl_lines_fat_raycasting WebGL / lines / fat / raycasting ]<br />
			[example:webgpu_lines_fat WebGPU / lines / fat / raycasting ]
		</p>

		<h2>Constructor</h2>

		<h3>[name]()</h3>
		<p>
			Creates a new geometry.
			Call [page:LineGeometry.setPositions setPositions] to add segments.
		</p>

		<h2>Properties</h2>
		<p>See the base [page:LineSegmentsGeometry] class for common properties.</p>

		<h3>[property:Boolean isLineGeometry]</h3>
		<p>Read-only flag to check if a given object is of type [name].</p>

		<h2>Methods</h2>
		<p>See the base [page:LineSegmentsGeometry] class for common methods.</p>

		<h3>[method:this fromLine]( [param:Line line] )</h3>
		<p>
			Copy the vertex positions of a [page:Line] object into this geometry.
			Assumes the source geometry is not using indices.
		</p>

		<h3>[method:this setColors]( [param:Array array] )</h3>
		<p>
			Replace the per-vertex colors.
			Every triple describes a line vertex: `[r1, g1, b1]`.
			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 three.
		</p>
