int operator!= (const SbBox2d &b1, const SbBox2d &b2)

The default constructor makes an empty box.

Constructs a box with the given corners.

xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box.

Constructs a box with the given lower left and upper right corners.

The coordinates of min should be less than the coordinates of max if you want to make a valid box.

Constructs an SbBox2d instance from the value in an SbBox2f instance.

Since

Coin 2.5

Constructs an SbBox2d instance from the value in an SbBox2s instance.

Since

Coin 2.5

Constructs an SbBox2d instance from the value in an SbBox2i32 instance.

Since

Coin 2.5

Reset the boundaries of the box.

xmin should be less than xmax and ymin should be less than ymax if you want to make a valid box.

Returns reference to self.

getBounds().

Reset the boundaries of the box with the given corners.

The coordinates of min should be less than the coordinates of max if you want to make a valid box.

Returns reference to self.

getBounds().

Reset the boundaries of the box with the given box boundaries.

Returns reference to self.

getBounds()

Reset the boundaries of the box with the given box boundaries.

Returns reference to self.

getBounds()

Reset the boundaries of the box with the given box boundaries.

Returns reference to self.

getBounds()

Returns the box boundaries.

setBounds(), getMin(), getMax().

Returns the box min and max corner points.

See also

setBounds(), getMin(), getMax().

Returns the lower left corner of the box.

See also

getOrigin(), getMax().

Returns the lower left corner of the box.

See also

getOrigin(), getMax().

Returns the upper right corner of the box.

See also

getMin().

Returns the upper right corner of the box.

See also

getMin().

Extend the boundaries of the box by the given point, i.e. make the box fit around the point if it isn't already situated within it.

Extend the boundaries of the box by the given box parameter. This is equal to calling the above method twice with the corner points.

Marks this as an empty box.

See also

isEmpty().

Check if this has been marked as an empty box.

See also

makeEmpty().

Check if the box has been correctly specified and by that virtue has 'positive' area, i.e. all coordinates of its upper right corner (the maximum point) are greater than the corresponding coordinates of its lower left corner (the minimum point).

Check if point lies within the boundaries of this box.

Check if box lies entirely or partially within the boundaries of this box.

Return the point on the box closest to the given point p. If the given point equals the center, the center point on the positive X-side is returned.

Check if a a line from a to b intersects the box, and return the coordinates of the union line in ia and ib.

This function is a Coin extension.

Returns the center point of the box.

Returns the coordinates of the box origin (i.e. the lower left corner).

See also

getMin().

Returns width and height of box.

Returns width and height of box as a 2D vector.

Since

Coin 3.0

Returns aspect ratio of box, which is defined as box width divided on box height.

Check b1 and b2 for equality.

Check b1 and b2 for inequality.
