Three.js Version: 82
I recently came across an interesting example on the official Three.js website:
In this example, I noticed the presence of yellow boxes surrounding the 3D models. Previously, in version 79, I used THREE.EdgesHelper to outline the 3D objects I created in Blender. However, in version 82, THREE.EdgesHelper was replaced by THREE.EdgesGeometry. I wanted to see a practical demonstration of this change, and the only example I found was the one mentioned above.
While exploring the properties of the line and BoxHelper objects, I couldn't find a solution to remove the yellow boxes.
For reference, here is the JSFiddle link: https://jsfiddle.net/4nbjvmpe/
Below is the code extracted from the JSFiddle:
