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
virtual

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
inlinevirtual

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
virtual

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

Reimplemented from DD::Image::PolygonPrimitive.

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

Draw the single face as a filled polygon.

Reimplemented from DD::Image::Primitive.
