<p>This material can be used in two ways:</p>
<ul>
<li>By rendering point primitives with <a href="Points.html">Points</a>. Since WebGPU only supports point primitives
with a pixel size of <code>1</code>, it's not possible to define a size.</li>
</ul>
<ul>
<li>By rendering point primitives with Sprites. In this case, size is honored,
see <a href="PointsNodeMaterial.html#sizeNode">PointsNodeMaterial#sizeNode</a>.</li>

						<p>This node property provides an additional way to set the point size.</p>
<p>Note that WebGPU only supports point primitives with 1 pixel size. Consequently,
this node has no effect when the material is used with <a href="Points.html">Points</a> and a WebGPU
backend. If an application wants to render points with a size larger than 1 pixel,
the material should be used with <a href="Sprite.html">Sprite</a> and instancing.</p>
						<p>Default is <code>null</code>.</p>
