You can capture and display feature lines. This enables you to display mesh edges extracted by feature angle (the angle between normal vectors of adjacent polygons). These lines are controlled by the Feature Angle node, which has properties and is subject to common menu items. The node appears only when the displayer's Feature lines property is activated.
To make this object available, expand the Scenes node and expand any scene that includes a geometry displayer (any default geometry, scalar or vector scene, or an empty scene in which you create a geometry displayer). Expand the Displayers node and select the geometry displayer node.
Tick the checkbox of the Feature lines property in the Properties window.
Once you activate the node, you can use its Feature Angle property to change the angle between surface elements that defines a feature. The smaller the angle, the more edges will be extracted.
