Understanding Sharp Faces and Sharp Edges #19

So far, I am using Sharp Faces and Sharp Edges in a blind mode. Not sure exactly what it is doing, but supposedly it is doing some kind of algorithm that continue to subdivide based on angle. Maybe I have seen something similar in the past using Processing. Not sure exactly how it works.

I play with angle, sometimes over 60° and it crashes Blender.

I use it with Plane and Box. I also noticed the differences of Top and Bottom.

I don't know how the mapping of texture with 2D Texture I am using (Coin) basically I wish it can do clever subdivision only on the area that got pushed by displacement.

I was expecting something like below: http://www.thisiscolossal.com/2018/01/painting-algorithms-dimitris-ladopoulos/

Hey sorry for the late reply. Have a look at the tutorial (at 1h:04m) for an explanation of sharp faces.

From blender manual: Select Sharp Edges This tool selects all edges between two faces forming an angle greater than the angle value, where an increasing angle selects sharper edges.

I think being able to track previously displaced area is useful. I will add this to my todo list
