class csPoly2D

The following class represents a general 2D polygon with a bounding box

Inheritance:

Public Methods

int	GetNumVertices () Get the number of vertices
csVector2*	GetVertex (int i) Get the specified vertex
csVector2*	GetVertices () Get the array with all vertices
void	MakeEmpty () Initialize the polygon to empty
void	MakeRoom (int new_max) Make room for at least the specified number of vertices
csVector2&	operator[] (int i) Get the specified vertex
void	SetVertices (csVector2 *v, int num) Set all polygon vertices at once

Protected Fields

csBox	bbox A 2D bounding box that is maintained automatically.
int	max_vertices
int	num_vertices
csVector2*	vertices The 2D vertices.

csVector2* vertices

The 2D vertices.

int num_vertices

int max_vertices

csBox bbox

A 2D bounding box that is maintained automatically.

csPoly2D(int start_size = 10)

Make a new empty polygon

csPoly2D(csPoly2D& copy)

Copy constructor.

virtual ~csPoly2D()

Destructor.

void MakeEmpty()

Initialize the polygon to empty

int GetNumVertices()

Get the number of vertices

csVector2* GetVertices()

Get the array with all vertices

csVector2* GetVertex(int i)

Get the specified vertex

csVector2& operator[] (int i)

Get the specified vertex

csVector2* GetFirst()

Get the first vertex

csVector2* GetLast()

Get the last vertex

void MakeRoom(int new_max)

Make room for at least the specified number of vertices

void AddVertex(const csVector2& v)

Add a vertex (2D) to the polygon

void AddVertex(float x, float y)

Add a vertex (2D) to the polygon

void SetVertices(csVector2 *v, int num)

Set all polygon vertices at once

csBox& GetBoundingBox()

Get the bounding box (in 2D space) for this polygon.

bool ClipAgainst(csClipper* view)

Clipping routines. They return false if the resulting polygon is not visible for some reason. Note that these routines must not be called if the polygon is not visible. These routines will not check that. Note that these routines will put the resulting clipped 2D polygon in place of the original 2D polygon.
