After successfully implementing raycasting on lines with R59 and displaying tooltips on mouseover, I encountered performance issues due to increasing data. This led me to switch from using THREE.Geometry to THREE.BufferGeometry. While everything else seems to be working fine, raycasting is no longer functioning as expected. There are no errors or any other indication when hovering over the lines.
Is it not possible to intersect raycasting on lines constructed with THREE.BufferGeometry?
Absolutely, Raycaster fully supports Line elements using BufferGeometry.
It's important to consider the threshold parameter as outlined in the documentation.
For a practical example, take a look at
Using three.js version r.130
