Intersect()

bool TRIANGLE_2D::Intersect ( const RAYSEG2D & aSegRay, float * aOutT, SFVEC2F * aNormalOut ) const

Parameters

aOutT

a value between 0.0 and 1.0 in relation to the time of the hit of the segment.

Implements OBJECT_2D.

Definition at line 80 of file triangle_2d.cpp.

Intersects()

bool TRIANGLE_2D::Intersects ( const BBOX_2D & aBBox ) const

overridevirtual

a.Intersects(b) ⇔ !a.Disjoint(b) ⇔ !(a ∩ b = ∅)

TODO: Optimize

Implements OBJECT_2D.

References OBJECT_2D::m_bbox.

IsBBoxInside()

INTERSECTION_RESULT TRIANGLE_2D::IsBBoxInside ( const BBOX_2D & aBBox ) const

overridevirtual

Test this object if it's completely outside, intersects, or is completely inside aBBox.

Returns

INTERSECTION_RESULT

Implements OBJECT_2D.

References OBJECT_2D::m_bbox, and MISSES.

IsPointInside()

bool TRIANGLE_2D::IsPointInside ( const SFVEC2F & aPoint ) const

overridevirtual

Implements OBJECT_2D.

Overlaps()

bool TRIANGLE_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.
