public class SbXfBox3d extends SbBox3d
3D box with an associated transformation matrix. A 3D box with an arbitrary transformation applied. This class is useful when a box will be transformed frequently; if an SbBox3f is used for this purpose it will expand each time it is transformed in order to keep itself axis-aligned. Transformations can be accumulated on an SbXfBox3d without expanding the box, and after all transformations have been done, the box can be expanded to an axis-aligned box if necessary.

    • extendBy

      public void extendBy(SbVec3d pt)
      Extends the box (if necessary) to contain the given 3D point. If the box has had a non-identity transformation applied using the setTransform() method, the point is assumed to be in the transformed space. For example, the following code sequence: 
       SbXfBox3d bbox = new SbXfBox3f();
 bbox.extendBy(new SbVec3f(0, 0, 0));
 SbMatrix trans = new SbMatrix();
 trans.setTranslate(new SbVec3f(1, 1, 1));
 bbox.setTransform(trans);
 bbox.extendBy(new SbVec3f(0, 0, 0));
      will result in a bounding box extending from (-1,-1,-1) to (0,0,0) in the bbox's local (untransformed) space.
      Overrides:
      extendBy in class SbBox3d

    • hasVolume

      public boolean hasVolume()
