Detailed Description

A dummy block defined by a 2d box size.

If the point is inside the bounding box it will return always true. However, the intersection with a ray will return always false. This is used as a sub block extracted from polygon (pcb polygon areas) and represents an area that is fully filled.

◆ Overlaps()

bool DUMMY_BLOCK_2D::Overlaps ( const BBOX_2D aBBox) const
overridevirtual

Test if the box overlaps the object.

Conformance Implements the Overlaps function from the OGC Simple Feature Specification at http://www.opengeospatial.org/standards/sfa. a.Overlaps(b) ⇔ ( dim(I(a)) = dim(I(b)) = dim(I(a)I(b))) ∧ (a ∩ b ≠ a) ∧ (a ∩ b ≠ b) It means that the result dimension of an overlap is the same dimensions of the bounding box (so the overlap cannot be a point or a line) and one of the boxes cannot full contain the other box.

Parameters
aBBoxis the bounding box to test.
Returns
true if the BBox intersects the object or is inside it.

Implements OBJECT_2D.
