void Rectangle (void) | Default constructor |
Creates an empty Rectangle .
|
void Rectangle (const Point& ccenter, const real aaxis_h, const real aaxis_v, [const real angle_x = 0, [const real angle_y = 0, [const real angle_z = 0]]]) | Constructor |
Creates a Rectangle in the x-z plane, centered at the origin,
with width == aaxis_h
(in the + or - x
direction),
and height == aaxis_v
(in the
+ or - z
direction).
If one or more of the arguments
angle_x, angle_y, or angle_z are used, it is rotated
by those amounts around the appropriate axes.
Finally, the Rectangle is shifted such that
its center lies at ccenter.
Point C(-1, -1, 1); Rectangle r(C, 3, 4, 30, 30, 30);

void set (const Point& ccenter, const real aaxis_h, const real aaxis_v, [const real angle_x = 0, [const real angle_y = 0, [const real angle_z = 0]]]) | Setting function |
Corresponds to the constructor described above. |
void Rectangle (const Point& p0, const Point& p1, const Point& p2, const Point& p3) | Constructor |
Creates Rectangle using four Point
arguments. The order of the arguments must correspond with a path
around the Rectangle .
This function does not currently check that the arguments yield a valid

void set (const Point& pt0, const Point& pt1, const Point& pt2, const Point& pt3) | Setting function |
Corresponds to the constructor above. |
Rectangle* create_new<Rectangle> (const Rectangle* r) | Template specializations |
Rectangle* create_new<Rectangle> (const Rectangle& r) |
Pseudo-constructors for dynamic allocation of Rectangles .
They create a Rectangle on the free store and allocate memory for it using
new(Rectangle) . They return a pointer to the new Rectangle .
If r is a non-zero pointer or a reference,
the new |
