[Users] Scrolling in OpendTect

[Paul de Groot]

Dear OD users,

It occurred to me that scrolling in OpendTect is another feature that 
might be a bit "hidden". Just in case, please find herewith an overview 
of "scrolling" in OpendTect.

   1. Fast (movie-style) scrolling of data, i.e. of stored cubes, or
      on-the-fly calcuated attributes. Use the volume viewer, position
      it around your target and use click and drag to move the inline,
      crossline or time slice display. You have to be in interact mode
      (arrow pressed) to do this. Note that you can have multiple
      inlines, crosslines and time sections per volume viewer (Add menu
      option).
   2. Scrolling of inlines, crosslines and time-slices. These are loaded
      or calculated per section, hence scrolling is not as fast as the
      previous option. Yet, it is possible to scroll to another section
      with just one mouse-click: Select the "Position" menu option.
      Toggle "Immediate update" on and set the "Step" to N. Let's say
      N=10 and the section is inline 200. To jump to 210 push the
      arrow-up of the Inline spin-box. Push it again to move to 220, 230
      etc. To move 10 positions back push the arrow-down button. Press
      OK and the Position window is closed.
   3. Scrolling through on-the-fly calcluated attributes. Press the
      "Evaluate attribute" icon in the Attribute set window to evaluate
      the effect of a parameter change on the current attribute. Use the
      slider to scroll through the attribute displays.
   4. Scrolling through saved horizon "Surface data". Load
      pre-calculated  Surface data and scroll through the data using
      Page-Up and Page-Down keys on your keyboard. This option is
      typically used for re-evaluation of spectral decomposition slices
      that were created and saved under the "Evaluate attribute" option
      in the Attribute window. The name of the current Surface data is
      displayed in the tree.

I hope this helps. Best regards,

Paul.
