Instance Property


The geometry element identifying which edges of the geometry’s surface should remain sharp after subdivision.


@property(nonatomic, retain) SCNGeometryElement *edgeCreasesElement;


This geometry element’s primitiveType value must be SCNGeometryPrimitiveTypeLine. 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.
