Enumeration CornerType

CornerType categorizes the nature of a corner based on the intersection of its adjoining sides.

• C++

typedef enum CornerType
{
   /* The sides of the corner is normally intersected. */
   CT_NORMAL_INTERSECTED = 0,
   /* The sides of the corner is T-intersected. */
   CT_T_INTERSECTED = 1,
   /* The sides of the corner is cross-intersected. */
   CT_CROSS_INTERSECTED = 2,
   /* The sides are not intersected but they definitely make up a corner. */
   CT_NOT_INTERSECTED = 3,
} CornerType;
