Detailed Description

Polygon primtive class consisting of n vertices. Can be defined as open or closed. If closed, the edge between the first and last vertex is added. All vertices must be coplanar otherwise unpredictable results will occur.

Member Function Documentation

void Polygon::copy ( const Polygon * b )

protected

Destructive copy.

References DD::Image::Primitive::copy(), and DD::Image::Primitive::normal_.

Primitive * Polygon::duplicate ( ) const

overridevirtual

Copy this Polygon into a new one, and return a pointer to it. Vertex data is duplicated, point indices are unchanged.

Implements DD::Image::Primitive.

bool DD::Image::Polygon::closed ( ) const

inline

Indicated whether the polygon is open or closed. If closed, the edge between the first and last vertex is added.

bool DD::Image::Polygon::IntersectsRay	(	const Ray &	ray,
		int	n,
		const PointList *	pointList,
		CollisionResult *	result
	)		const

inlineoverridevirtual

Test for the intersection of this primitive with a given ray .

Reimplemented from DD::Image::Primitive.

References DD::Image::Primitive::PolyIntersectsRay().

void Polygon::tessellate	(	Scene *	scene,
		PrimitiveContext *	ptx
	)		const

overridevirtual

Subdivide the polygon into triangles and add them to the rendering pipeline.

Implements DD::Image::Primitive.

void Polygon::draw_solid_face	(	int	n,
		ViewerContext *	ctx,
		PrimitiveContext *	ptx
	)		const

overridevirtual

Draw the single face as a filled polygon.

Reimplemented from DD::Image::Primitive.
