The following new features were implemented in the most recent version:

Radia 4.09

• New methods of segmentation: subdivision according to elliptic cylinder and by a set of parallel planes (new options in radObjDivMag<). The new methods of segmentation allow to strongly improve the efficiency of solving the iron-dominated geometries.
• New examples illustrating the use of the new subdivision methods for the efficient simulation of dipole and multipole magnets for particle accelerators.
• Miscellaneous small improvements: a possibility of "releasing" symmetries at duplication of the objects with the symmetries applied (new option in radObjDpl<); axes of the laboratory Cartesian frame in active 3D graphics (new options in radObjDrwQD3D<); bug fixes.

New features in previous versions:

Radia 4.08

• Active 3D graphics facilitated by QuickDraw 3D library from Apple (new function  radObjDrwQD3D<). To make use of this new functionality, one needs to have the QuickDraw 3D 1.5 or later installed on one's system. The versions of QuickDraw 3D for Power Macintosh and Windows 95/NT can be downloaded from the Apple Web site for free (http://www.apple.com/quicktime/qd3d/).

Radia 4.07

• More simple definition of complicated geometries: Automatic generation of convex polyhedrons based on the information on their horizontal slices (new functions radObjMltExtPgn< and radObjMltExtRtg<).
• More flexible segmentation: Arbitrary cutting of objects by a plane; subdivision of objects in their local frames and in the laboratory frame (new function  radObjCutMag< and new options in radObjDivMag<).
