edgeCreasesElement
The geometry element identifying which edges of the geometry’s surface should remain sharp after subdivision.
Declaration
var edgeCreasesElement: SCNGeometryElement? { get set }Discussion
This geometry element’s primitiveType value must be SCNGeometryPrimitiveType.line. The geometry element’s data is an array of vertex indices, each pair of which defines a line segment identifying an edge to be treated as a crease during subdivision. Use the edgeCreasesSource property to specify the smoothness or sharpness of each crease.
