class csClipper

The csClipper class is an abstract parent to all 2D clipping objects

Inheritance:

Public Methods

virtual bool Clip(csVector2 *Polygon, csVector2* dest_poly, int Count, int &OutCount)

Clip a set of 2D points and return in 'dest_poly'

virtual bool Clip(csVector2 *Polygon, int &Count, int MaxCount, csBox *BoundingBox)

Clip a set of 2D points and return them in the same array

virtual int GetNumVertices()

Return number of vertices for this clipper polygon.

virtual const csVector2 GetVertex(int i)

Return vertex at index for this clipper polygon.

virtual bool IsInside(float x, float y)

Return true if given point is inside (or on bound) of clipper polygon.

Protected Fields

static csPoly2DPool polypool

This variable holds a pool for 2D polygons as used by the clipper.

static csPoly2DPool polypool

This variable holds a pool for 2D polygons as used by the clipper.

virtual bool Clip(csVector2 *Polygon, csVector2* dest_poly, int Count, int &OutCount)

Clip a set of 2D points and return in 'dest_poly'. 'dest_poly' must be big enough to hold the clipped polygon. Return false if polygon is not visible (clipped away).

virtual bool Clip(csVector2 *Polygon, int &Count, int MaxCount, csBox *BoundingBox)

Clip a set of 2D points and return them in the same array. On input MaxCount contains number of elements that Output can hold. On output Count is set to number of vertices in output polygon.

virtual bool IsInside(float x, float y)

Return true if given point is inside (or on bound) of clipper polygon.

virtual int GetNumVertices()

Return number of vertices for this clipper polygon.

virtual const csVector2 GetVertex(int i)

Return vertex at index for this clipper polygon.
