Dolphin 3D, Version 2.3 now available

A new Dolphin 3D release is now available (Version 2.3)! Several major features have introduced, including multiple-view layouts (pictured), Window Leveling, better movie transitions and more "3D looking" volume.

Check them out! Here are the excruciating details of this cool, new version (you can also look this up under Help "About Dolphin 3D..." in the program). Enjoy! You should receive this version online automatically. Let us know if you have questions.

  1. Added a variety of layouts to the main window: “3+1,” 2x2,” Sagittal, Transverse, Coronal, etc. These layouts are extremely useful in examining and analyzing a volume, or in identifying landmarks. The Sagittal, Transverse and Coronal views are useful in locating landmarks on the same plane.
  2. Added the ability to insert saggital, transverse and coronal planes into the volumetric view for reference. This is especially useful in digitizing 3D volume.
  3. Window Leveling feature is available in most slice views (i.e., saggital, transverse or Coronal)
  4. In general, Window Leveling feature has been enhanced to show soft-tissue better.
  5. In the main view, added symmetry caliper, which can be used in the volume, sagittal and coronal views.
  6. In Orientation, added BOTTOM and LEFT views; “Planes of Section” view is also added.
  7. Orientation may now be performed with a 3D photo view (linked with the volume).
  8. In Orientation, added Symmetry Caliper function.
  9. Greatly expanded “Digitize Landmarks…” (Note: any previously saved, pre-v2.0, digitization landmarks will be lost and no longer be supported).
  10. In Digitize Landmarks, Measurements tab, you can measure end-to-end (linear) distances; you no longer requires to hold key (though still use the right-button and choose the start/end points).
  11. In Digitize Landmarks, Measurement tab, you can measure any 3D angles based on 3-points digitized
  12. In Digitize Landmarks, you can choose to use the 3D photo as the default “soft tissue,” as opposed to the volume’s soft tissue surface.
  13. Digitized landmarks can now be easily relocated (click, hold and move the point).
  14. Tooltip depicts the landmark name when hovering the mouse over a landmark.
  15. You can now link two distinct 3D photo surfaces to one 3D volume. For example, a smiling and a non-smiling 3D surface for a same patient’s CBCT volumetric scan. 3D surface scans can be acquired from any 3D camera system that supports the .OBJ and .BMP format (jointly).
  16. In the Main View, the Clipping Plane #2 has “r” and “l” buttons, which automatically cuts away either side of the volume from the defined mid-sagittal plane (defined in Orientation).
  17. In Build Radiographs, added the industry-standard "Ray-Sum" radiograph rendering method.
  18. “Copy” now copies the entire displayed layout to the Windows Clipboard, including any digitized points and measurement lines.
  19. In Make Movies, Dolphin 3D now generates in-between transition frames in varying volumetric segmentations. For example, Dolphin now smoothly transitions between a "Soft Tissue" volume object key frame to a "Hard Tissue" key frame. Also, Dolphin now supports (the gradual) altering a volume's segmentation settings (i.e., transition from a skull-looking volume to merely teeth by using gradually narrowed voxel density range results as key frames). This feature would only applies to the movie script created for a specific patient. When you've created a movie script for a patient that contains alterations of the volume's segmentations, and you load another patient's volumes, that aspect of the script will be reset to the new patient's default segmentations.
  20. Added "Depth Cuing" factor to further enhance the "3D look" of the the volume's appearance. For example, you will now notice that the parts of an object closer to you are lighter than parts that are further away from you (darker). You may adjust this setting under Options Lighting... You can turn the option off completely or choose any range in between. We recommend that you use the default settings.
  21. Reset the overall default lighting, color and surface settings. We've redesigned all the default settings of a volume's ambient lighting and surface texture settings. You may readjust to your preference under Options Lighting...
  22. In Orientation, created "Auto Alignment Tool" section; this is still work-in-progress. "Using 3-Point Plane" is probably better for Front orientation: place the end points of the triangle in the appropriate locations, preferably along the soft tissue midline of a subject (try the midpoint between the eyebrows, nasal tip and midpoint of the philtrum, respectively); then, click "Make Vertical" will allow Dolphin to place the 3 points along a straight, vertical line, effectively altering the pitch and yaw of the subject. Similarly, "Using Line" for Front, Right or Left orientations: place the line (or the end points) anywhere you desire and click "Make Vertical" or "Make Horizontal" to make Dolphin to alter the orientation of the subject so that the end points would be along a vertical line or a horizontal line, respectively.

Dolphin 3D keeps getting better and better. I hope to see everyone in Scottsdale at the annual Dolphin meeting where we will learn to really tweak Dolphin 3D!
