Detailed Description

A convex polygon, one type of GeometricShape. This determines a polygon conposed by at least 3 vertices.

Constructor & Destructor Documentation

pyramidworks::geometry::ConvexPolygon::ConvexPolygon

(

const std::vector< ugdk::math::Vector2D > &

vertices

)

Parameters

vertices

The list of vertices of the polygon, in local coordinates (0,0 is the "center", where this polygon is positioned). vertices[i] and vertices[i+1] form a edge, and vertices[n]-vertices[0] is the closing edge.

Parameters

position

The absolute position for this shape.

Returns

A 2D Box around this shape

Implements pyramidworks::geometry::GeometricShape.

bool pyramidworks::geometry::ConvexPolygon::Intersects ( const ugdk::math::Vector2D &  this_pos, const GeometricShape *  obj, const ugdk::math::Vector2D &  that_pos  ) const

virtual

Checks if this shape intersects another shape.

Parameters

this_pos	The absolute position for this shape.
obj	The shape to compare with.
that_pos	The absolute position of the other shape.

Returns

True if there's an intersection.

bool pyramidworks::geometry::ConvexPolygon::Intersects ( const ugdk::math::Vector2D &  this_pos, const Rect *  obj, const ugdk::math::Vector2D &  that_pos  ) const

virtual

Checks if there's an intersection with a Rect.

Parameters

this_pos	The absolute position for this shape.
obj	The shape to compare with.
that_pos	The absolute position of the other shape.

Returns

True if there's an intersection.

bool pyramidworks::geometry::ConvexPolygon::Intersects ( const ugdk::math::Vector2D &  this_pos, const Circle *  obj, const ugdk::math::Vector2D &  that_pos  ) const

virtual

Checks if there's an intersection with a Circle.

Parameters

this_pos	The absolute position for this shape.
obj	The shape to compare with.
that_pos	The absolute position of the other shape.

Returns

True if there's an intersection.

Implements pyramidworks::geometry::GeometricShape.

bool pyramidworks::geometry::ConvexPolygon::Intersects ( const ugdk::math::Vector2D &  this_pos, const ConvexPolygon *  obj, const ugdk::math::Vector2D &  that_pos  ) const

virtual

Checks if there's an intersection with a Convex Polygon.

Parameters

this_pos	The absolute position for this shape.
obj	The shape to compare with.
that_pos	The absolute position of the other shape.

Returns

True if there's an intersection.
