I am new to three.js and having a play. I have successfully loaded in a mountain (collada file) made in SketchUp but want to be to add clickable elements to the terrain.
I am trying to add clickable elements to the terrain. I have so far create a click listener which tells me mouse coordinates but unsure how to add elements to the terrain and figuring our heights
Any help would be gratefully received as I’d love to get an understanding of all this
