General Polygon Shape Hints
A general polygon has a shape hint associated with it that specifies the shape of the general polygon. A general polygon's shape hint may be used by a renderer to optimize drawing the polygon.
typedef enum TQ3GeneralPolygonShapeHint {
kQ3GeneralPolygonShapeHintComplex,
kQ3GeneralPolygonShapeHintConcave,
kQ3GeneralPolygonShapeHintConvex
} TQ3GeneralPolygonShapeHint;
Constant descriptions
- kQ3GeneralPolygonShapeHintComplex
- The general polygon consists of more than one contour, is self-intersecting, or is not known to be either concave or convex.
- kQ3GeneralPolygonShapeHintConcave
- The general polygon has exactly one contour, which is concave.
- kQ3GeneralPolygonShapeHintConvex
- The general polygon has exactly one contour, which is convex.
