[FEATURE SUGGESTION] Ability to highlight a specific edge #1258

See https://github.com/xeokit/xeokit-sdk/issues/1255

Possible strategy:

when snap-picking to an edge, return an ID of the edge primitive in the snap result
query the snapped entity for the coordinates of the edge end points
temporarily create an HTML element, overlaid over the edge, that resembles the highlighted edge

Amoki commented 1 year ago

If it is possible to render the edge differently (like selection or hovering) instead of using HTML, it will be prettier and less prone to problems like z-index fighting of overlap with markers imho
