Detailed Description
Bounding Box.
A helper class for working with boxes. It runs at F32 precision.
Public Attributes
Point3I maxExtents
Maximum extents of box.
Point3I minExtents
Minimum extents of box.
Public Functions
Box3I()
Box3I(const Point3I & in_rMin, const Point3I & in_rMax, const bool in_overrideCheck)
Create a box from two points.
Normally, this function will compensate for mismatched min/max values. If you know your values are valid, you can set in_overrideCheck to true and skip this.
Parameters:
| in_rMin | Minimum extents of box. |
| in_rMax | Maximum extents of box. |
| in_overrideCheck | Pass true to skip check of extents. |
Box3I(S32 xmin, S32 ymin, S32 zmin, S32 max, S32 ymax, S32 zmax)
Create a box from six extent values.
No checking is performed as to the validity of these extents, unlike the other constructor.
extend(const Point3I & p)
getCenter(Point3I * center)
Get the center of this box.
This is the average of min and max.
intersect(const Box3I & in_rIntersect)
Perform an intersection operation with another box and store the results in this box.
isContained(const Box3I & in_rContained)
Check to see if another box is contained in this box.
isContained(const Point3I & in_rContained)
Check to see if a point is contained in this box.
isOverlapped(const Box3I & in_rOverlap)
Check to see if another box overlaps this box.
isValidBox()
Check that the box is valid.
Currently, this just means that min < max.
