Detailed Description

Make solid geometry for objects on layers.

The operation is in the form (A - B) /\ C For almost all of the layers it translate something like: A (a via, a track, pad, polygon), B (a via hole, a THT hole, .. ), C the board (epoxy) For layers like Solder mask that are negative: A ( epoxy ), B( pads, polygons, ..), C=1

Some notes: BODY = PCB_outlines - PCB_holes - (Modules_THT_holes + VIA_THT_holes)

Plated_vias_and_holes = Tracks.Vias + Modules.PlatedHoles

Layer.cu = ( Tracks.cu + Modules_Pads.cu + Modules_Graphics.cu + Layer_zones.cu + PCB_drawings.cu - Layer_VIA_holes ) & BODY

Layer.Mask = BODY - (PCB_drawing.Mask + Modules_Graphics.Mask + Modules_Pads.Mask + Layer_zones.Mask ) Layer.Paste = (PCB_drawing.Paste + Modules_Graphics.Paste + Modules_Pads.Paste + Layer_zones.Paste) & BODY Layer.Silk = (PCB_drawing.Silk + Modules_Graphics.Silk + Modules_Pads.Silk + Layer_zones.Paste) & BODY

BODY = A - B /\ 1 Layer.cu = A - B /\ C Layer.mask = A - B /\ 1 Layers.Paste = A - 0 /\ C Layers.Silk = A - 0 /\ C

BODY = P - T /\ 1 Layer.cu = T - H /\ BODY Layer.mask = BODY - M /\ 1 Layers.Paste = P - 0 /\ BODY Layers.Silk = S - 0 /\ BODY

◆ IsBBoxInside()

◆ Overlaps()

bool LAYER_ITEM_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

aBBox is the bounding box to test.

Returns: true if the BBox intersects the object or is inside it.

Implements OBJECT_2D.
