20 Managing Bounding Boxes
Q3BoundingBox_UnionPoint3D
function to find the union of a bounding box and a three-dimensional point.
TQ3BoundingBox *Q3BoundingBox_UnionPoint3D ( const TQ3BoundingBox *bBox, const TQ3Point3D *pt3D, TQ3BoundingBox *result);bBox
A pointer to a bounding box.pt3D
A three-dimensional point.result
On exit, a pointer to the union of the specified bounding box and the specified point.
Q3BoundingBox_UnionPoint3D
function returns, as its function result and in the result
parameter, a pointer to the bounding box that is the union of the bounding box specified by the bBox
parameter and the three-dimensional point specified by the pt3D
parameter. The result
parameter can point to the memory pointed to by bBox
, thereby performing the union operation in place.
