I want a function to view the terrain shape and measure its height. How can I draw a line from 2 points on the surface of the model.
Can anyone give me some directions. Any information is precious to me.
and from the Collection of examples from discourse.threejs.org
Thank you for your response. But what I want is a line connecting 2 points and lying on the surface of the object, not a line segment representing the distance of those 2 points.
One of solution is using geometry intersection. Line like thin box.
