[SoC] GSoC 2014 - OTB project weekly report: week 12

[Martina Porfiri]

​Hi all,

below you can find the week report n°
 ​12
.
 Work done

   - I have continued to implement and refine GlCoverFlowView class (ex
   GlView_CF) in order to switch from a static to a dynamic CoverFlow mode,
   running the otbglcoverflow (ex basicviewer) application


   - Following mentors suggestions, I was focused on two issues:
      - enabling to load and manage a generic number of images (not just
      three like before)
      - activating images movement when pressing specific keys (left and
      right)

In order to perform this I have implemented four new functions in
GlCoverFlowView class, in particular:

   1. 'First_Pos':where the image positions are initialized
   2. 'MoveLeft':where the image to be rendered in evidence is selected
   when the left key is pressed
   3. 'MoveRight':where the image to be rendered in evidence is selected
   when the right key is pressed
   4. 'UpdatePos':where the image positions are updated when the left or
   right keys are pressed


   - In this way, running otbglcoverflow application one can load n images
   and, pressing left and right keys, see them (just a part) moving in a
   'coarse' CoverFlow mode. At the moment there are two main limitations (see
   a brief demonstration at CoverFlow
   <https://drive.google.com/file/d/0B2-zUmOVbsQmYkhaaHh1WW5CSk0/edit?usp=sharing>):

      - pressing keys beyond the last (or first) image stops the movement
      - images do not page through along the x direction, thus images
      loaded beyond screen edges are not visible

Work to be done in the next week

   - I will refine GlCoverFlowView class in order to pass actual
   limitations and obtain a more efficient CoverFlow


   - ​​
   I will test the otbglcoverflow application controls and interaction with
   several images (using available dataset)
   ​, discussing results with mentors​


   - I will generate and complete code documentation (both using Doxygen
   and updating remote repository) in view of the final 'pencil down'

 Blocking issues

   - None in particular
