20 Managing Bounding Boxes
Q3BoundingBox_UnionRationalPoint4D
function to find the union of a bounding box and a rational four-dimensional point.
TQ3BoundingBox *Q3BoundingBox_UnionRationalPoint4D ( const TQ3BoundingBox *bBox, const TQ3RationalPoint4D *pt4D, TQ3BoundingBox *result);bBox
A pointer to a bounding box.pt4D
A rational four-dimensional point.result
On exit, a pointer to the union of the specified bounding box and the specified point.
Q3BoundingBox_UnionRationalPoint4D
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 rational four-dimensional point specified by the pt4D
parameter. The result
parameter can point to the memory pointed to by bBox
, thereby performing the union operation in place.
