Learn Three.js for 3D Computer Graphics

Geometries We Can Use for Debugging

Explore how to use Three.js helper geometries, EdgesGeometry and WireframeGeometry, to debug 3D objects. Understand wrapping existing geometries to display edges or wireframes, adjust threshold for edge rendering, and visualize shapes without faces for clearer inspection.

We'll cover the following...

Three.js comes with two helper geometries out of the box that make it easier to see the details or just the outline of a geometry:

  • THREE.EdgesGeometry provides a geometry that only renders the edges of a geometry.

  • THREE.WireframeGeometry renders just the geometry without showing any faces.

First, let’s look at THREE.EdgesGeometry.

The
