Constructor & Destructor Documentation G3D::Rect2D::Rect2D (  )  [inline] G3D::Rect2D::Rect2D ( const Vector2 &  wh  )  [inline] Creates a rectangle at 0,0 with the given width and height. G3D::Rect2D::Rect2D ( const Rect2D &  a, const Rect2D &  b   ) [inline] Computes a rectangle that contains both a and b. Member Function Documentation float G3D::Rect2D::area (  )  const [inline] Rect2D G3D::Rect2D::border ( float  delta  )  const [inline] Returns a new Rect2D that is bigger/smaller by the specified amount (negative is shrink. ) Vector2 G3D::Rect2D::center (  )  const [inline] template<class T> void G3D::Rect2D::clip ( const Array< T > &  inPoly, Array< T > &  outPoly   ) const [inline] Clips so that the rightmost point of the outPoly is at rect.x1 (e.g. a 800x600 window produces rightmost point 799, not 800). The results are suitable for pixel rendering if iRounded. Templated so that it will work for Vector2,3,4 (the z and w components are interpolated linearly). The template parameter must define T.lerp and contain x and y components. If the entire polygon is clipped by a single side, the result will be empty. The result might also have zero area but not be empty. bool G3D::Rect2D::contains ( const Rect2D &  r  )  const [inline] bool G3D::Rect2D::contains ( const Vector2 &  v  )  const [inline] Vector2 G3D::Rect2D::corner ( int  i  )  const [inline] Returns the corners in the order: (min,min), (max,min), (max,max), (min,max). float G3D::Rect2D::height (  )  const [inline] Rect2D G3D::Rect2D::intersect ( const Rect2D &  other  )  const [inline] Returns the overlap region between the two rectangles. This may have zero area if they do not intersect. See the two-Rect2D constructor for a way to compute a union-like rectangle. bool G3D::Rect2D::intersects ( const Rect2D &  r  )  const [inline] True if there is non-zero area to the intersection between this and r. Note that two rectangles that are adjacent do not intersect because there is zero area to the overlap, even though one of them "contains" the corners of the other. bool G3D::Rect2D::intersectsOrTouches ( const Rect2D &  r  )  const [inline] Like intersection, but counts the adjacent case as touching. Rect2D G3D::Rect2D::largestCenteredSubRect ( float  ww, float  hh   ) const [inline] Returns the largest, centered Rect2D that can fit inside this while maintaining the aspect ratio of x:y. Convenient for displaying images in odd-shaped windows. Rect2D G3D::Rect2D::lerp ( const Rect2D &  other, float  alpha   ) const [inline] Rect2D G3D::Rect2D::operator * ( float  s  )  const [inline] bool G3D::Rect2D::operator!= ( const Rect2D &  other  )  const [inline] Rect2D G3D::Rect2D::operator+ ( const Vector2 &  v  )  const [inline] Rect2D G3D::Rect2D::operator- ( const Vector2 &  v  )  const [inline] Rect2D G3D::Rect2D::operator/ ( float  s  )  const [inline] bool G3D::Rect2D::operator== ( const Rect2D &  other  )  const [inline] Vector2 G3D::Rect2D::wh (  )  const [inline] Width and height. float G3D::Rect2D::width (  )  const [inline] float G3D::Rect2D::x0 (  )  const [inline] Vector2 G3D::Rect2D::x0y0 (  )  const [inline] Min, min corner.
