1. 3D TERRAIN VIEWER: Basics HYPACK 2016

2. 3-D Terrain Viewer (3DTV)

3. Basics o 3DTV takes XYZ files and generates a TIN MODEL. o A ‘camera’ can then be moved about the surface to view it from different perspectives. Presentations: TINTIN Color-coded by DepthColor-coded by Depth TIF OverlayTIF Overlay

4. Camera Control Window  Use the Camera Position Window to set the position of the camera.  Left-Click: Place the camera at the location.  Left-Click and Drag: Place the camera at the left-click location and set camera’s path to the drag.  Right-Click: Rotate the camera in the direction of the click.  Left-click in the right-hand portion of the window to set the camera’s height.

5. Light Control Window  Left-click in the Light Position Window to set the position (left region) or elevation (right region) of the light source.  In ‘Miner’s Lamp’ mode, the light source is always positioned at the vessel X-Y.  You can control the elevation of the light while in Miner’s Lamp mode.

6. FLIGHT MODES Flight Mode Free FlightYou have complete control in the path of the camera and the direction it points. Follow PathThe camera moves forwards and backwards along a planned line. It can point any direction, but cannot be moved off the line. Circle FlightThe camera travels in a circle about a point of interest. Attached to Vessel The camera travels relative to a vessel being tracked in HYPACK’s SURVEY program.

7. Flight Modes: Free Flight Mode  Free Flight: Control the camera’s flight with the Camera Control window or the Compact Camera Control window.

8. Flight Modes: Follow Path Mode  Moves the camera forward/backward along a planned line (*.LNW).  Camera cannot move off the planned line.  Camera can rotate while moving along the planned line.

9. Flight Modes: Circle Flight  In ‘Circle Flight’ mode, the camera travels in a circle about an object.  The camera always points towards the center of the circle.

10. Flight Modes: Attached to Vessel  In ‘Attached to Vessel’ mode, the camera in 3DTV is placed relative to the vessel position obtained from SURVEY. Center Vessel Lock on Vessel Next Vessel Previous Vessel

11. 3DTV MATRIX  3DTV can load a MTX file, instead of an XYZ file.  When the MTX file is modified by DREGEPACK®, the changes are transmitted to 3DTV.

12. Attached to Vessel: Water Surface display  3DTV can display the Water Surface. You can control the transparency level and size of waves.  In ‘Attached to Vessel’ mode, changes in the Tide Correction are used to correct the z-level of the water surface in 3DTV.

13. Attached to Vessel: Draft Setting The vertical position of each vessel in 3DTV is modified as the draft changes in SURVEY.

14. Nature Settings Warning: Nature settings will put your video card to the test. If you have a cheap video card, 3DTV may not be able to perform as designed. Enjoy the bird sounds.

15. Saving to AVI  Click AVI icon to start logging to AVI.  Click AVI icon again to terminate logging to AVI.  Give it a name.  Warning: The AVI file can grow at over 1Mb/second. Check your AVI settings (Under the Camera – Settings menu item) before you start to log your AVI videos. Specify the Temporary File first!!!

16. Saving to BMP/JPG/TIF  You can save the view in the 3D Terrain Window by clicking the ‘Snapshot’ icon. BMPBMP JPGJPG TIF (not a GeoTIF)TIF (not a GeoTIF) 1 Picture A series of pictures at a timed interval Record a movie for playback in 3DTV

17. Vertical Exaggeration  Vertical Exaggeration (VE) can be used to add more relief to the surface model.  It’s located under the View menu.  VE is applied to terrain and all objects. Option to omit vessels and floating objects from VE.

18. Frame Rates  Frame rate menu determines how many times per second 3DTV tries to update your screen.  3DTV eats a lot of CPU time.  If the response to menu-clicks is slow, select a slower frame rate.  Check out your frame rate settings by looking at Windows Task Manager performance graph.

19. Packing and Un-Packing a 3DTV Project  Pack: Saves all files associated with a project to a zipped file.  XYZ  3OD  3OP  CHN  Settings  Screen Layout  Unpack: Copies all associated files to the target directory.

20. Creating Geo TIF files for draping in 3DTV HYPACK 2015

21. Creating a GeoTIF Save areas of the HYPACK® Shell’s map view to TIF.. Create a TIF mosaic from side scan data in SIDE SCAN MOSAIC.

22. 3DTV: Overlaying a TIF File Load GeoTIF under ‘Terrain – Photo Texture Settings’ AVI

23. 3DTV: TIF Files Outside the XYZ Surface You can extend the TIF file outside the area of the XYZ file by clicking the ‘Show’ check box in the Photo-Texture Settings window.

24. 3DTV: Transparency You can adjust the transparency of the TIF (over the surface model) by adjusting the Photo-Texture Transparency.

25. Photo Texture Settings Window  Photo-texture reloading:  Disk Space  Speed  Color of Uncovered Terrain  Gray  Color Scale  Photo-texture Quality  Some OpenGL implementations cannot handle the highest quality.  If you can’t see the TIF, try reducing the quality.

26. Creating and adding 3D objects HYPACK 2016

27. 3D Shapes: Created in 3D SHAPE EDITOR Object Types Usage Static An object fixed in space (X-Y-Z) and heading. Multi-Static Multiple instances of the same Static object. Floating An object fixed in X-Y that moves vertically with the water surface. Multi-Floating Multiple instances of the same Floating object. Pipe A constant-diameter pipe. Poles Telephone poles and wires draped between them. Create your 3-D objects in the 3D SHAPE EDITOR program, or use an existing shape from the..\Shapes folder.

28. Object Deployment: Point Object

29. Object Deployment: Multi-Floating Use a *. 3op file to position multiple instances of the same object. (It’s an ASCII XYZ file with heading added at the end.) Sample *.3op file in Notepad.

30. Pipeline Object  Pipe vertices (X-Y-Z) are read from *.3op file.  Make it with a text editor (Notepad).
