The SbBox2i32 class is a 2 dimensional box with int32_t coordinates.
This box class is used by other classes in Coin for data exchange. It provides storage for two box corners with int32_t coordinates.
|
inline |
The default constructor makes an empty box.
|
inline |
Constructs a box with the given corner coordinates.
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 corners.
The coordinates of min should be less than the coordinates of max if you want to make a valid box.
|
inlineexplicit |
Constructs a box with coordinates from box, converting the coordinates to 32-bit integers
|

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.
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.
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
References SbBox2s::getMax(), SbBox2s::getMin(), SbBox2s::isEmpty(), makeEmpty(), and SbVec2i32::setValue().
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
References SbBox2f::getMax(), SbBox2f::getMin(), SbBox2f::isEmpty(), makeEmpty(), and SbVec2i32::setValue().
Reset the boundaries to the boundaries of the given box.
Returns reference to self.
References SbBox2d::getMax(), SbBox2d::getMin(), SbBox2d::isEmpty(), makeEmpty(), and SbVec2i32::setValue().
|
inline |
Returns the box boundary coordinates.
Returns the box corner points.
|
inline |
Returns the minimum point. This should usually be the lower left corner point of the box.
Referenced by extendBy(), intersect(), operator==(), SbBox2s::setBounds(), SbBox2f::setBounds(), and SbBox2d::setBounds().
|
inline |
Returns the minimum point. This should usually be the lower left corner point of the box.
|
inline |
Returns the maximum point. This should usually be the upper right corner point of the box.
Referenced by extendBy(), intersect(), operator==(), SbBox2s::setBounds(), SbBox2f::setBounds(), and SbBox2d::setBounds().
|
inline |
Returns the maximum point. This should usually be the upper right corner point of the box.
void SbBox2i32::extendBy | ( | const SbVec2i32 & | point | ) |
Extend the boundaries of the box by the given point, i.e. make the point fit inside the box if it isn't already within it.
References SbVec2i32::setValue().
Referenced by extendBy().
void SbBox2i32::extendBy | ( | const SbBox2i32 & | box | ) |
Extend the boundaries of the box by the given box parameter. This is equal to calling extendBy() twice with the corner points.
References extendBy(), getMax(), getMin(), and SoDebugError::postWarning().
void SbBox2i32::makeEmpty | ( | void | ) |
Marks this as an empty box.
References SbVec2i32::setValue().
Referenced by setBounds().
|
inline |
Check if this has been marked as an empty box.
Referenced by SbBox2s::setBounds(), SbBox2d::setBounds(), and SbBox2f::setBounds().
|
inline |
Check if the box has "positive" area, i.e. the lower left corner is actually lower and more to the left than the other corner point.
SbBool SbBox2i32::intersect | ( | const SbVec2i32 & | point | ) | const |
Check if the given point lies within the boundaries of this box.
SbBool SbBox2i32::intersect | ( | const SbBox2i32 & | box | ) | const |
|
inline |
Returns the center point of the box.
|
inline |
Returns the coordinates of the box origin (i.e. the lower left corner).
|
inline |
Returns width and height of box.
|
inline |
Returns aspect ratio of box, which is defined as box width divided on box height.
Check b1 and b2 for inequality.
