APEX 2012 includes several enhancements for ray tracing: trace rays with improved speed via complex vs. simple feature recognition, now always on during APEX ray traces; trace rays one step at a time with the Step Trace feature found on the Trace tab; and use the new Move Rays and Focus options during ray trace post-processing to move rays along their propagation direction, and to find the best 3D-focal point of selected ray data.
