csPlane	plane The plane.
csPolyIndexed	polygon The 3D polygon.

Inherited from csPolygonInt:

csPolyIndexed polygon

The 3D polygon.

csPlane plane

The plane.

csBspContainer* parent

The parent.

csObject* originator

The original object for which this polygon is a bounding box polygon.

virtual ~csBspPolygon()

Destructor.

csBspContainer* GetParent()

Get the parent container.

void SetParent(csBspContainer* par)

Set the parent container.

csObject* GetOriginator()

Get the original object for which this polygon is a bounding box polygon

void SetOriginator(csObject* orig)

Set the original object.

csPolyIndexed& GetPolygon()

Get the reference to the polygon.

void SetPolyPlane(const csPlane& pl)

Set the plane for this polygon.

csPlane* GetPolyPlane()

Return the plane of this polygon.

int Classify(csPolygonInt* poly)

Classify a polygon with regards to this one.

void SplitWithPlane(csPolygonInt** front, csPolygonInt** back, csPlane& split_plane)

Split this polygon with the given plane (A,B,C,D).

bool SamePlane(csPolygonInt* p)

Return true if this polygon and the given polygon are on the same plane.

int GetType()

Return 2 to indicate it is a bsp polygon.

void Transform(const csTransform& trans)

Transform the plane of this polygon.

void World2Camera(const csTransform& trans)

Transform the plane of this polygon from world to camera space

bool ClipToPlane(csPlane* portal_plane, const csVector3& v_w2c, csVector3*& pverts, int& num_verts, bool cw = true)

Clip this polygon the Z plane and if portal_plane is given also clip the polygon to that plane. @@@ NOTE @@@ This function is almost identical to one in csPolygon3D. It should be possible to reuse that code.

bool DoPerspective(const csTransform& trans, csVector3* source, int num_verts, csPolygon2D* dest, bool mirror)

Perspective correct a polygon. Note that this function is nearly identical to a version in csPolygon3D. It should be possible to reuse that code.

This class has no child classes.
