Detailed Description

The FitToBoxTransform node is a MatrixTransform that is used when one wants to transform a part of a scene into a specific region in the coordinate space.

The region to transform into is defined by a box using the boxCenter and boxSize fields. The bounding box of the FitToBoxTransform node is then used to determine the scale and translation needed to fit that bounding box into the box defined. The uniformScalingOnly determines if the scaling should be uniform or if nonuniform scaling can be used. Nonuniform scaling will fit the children more accurately into the box, while uniform scaling will preserve the ratio of the dimentions of the objects. The active field can be used to control if the transformation matrix should be updated or not. If active is true the matrix will be updated.
