Requirements

There are two parts to the project:

  • Video / related meta data rendering and interactions.
  • Displaying video / meta data in geospatial context.

As per our discussion we have gathered following requirements for the project.

  • Easy to put together.
  • Provides 2D and 3D mode where in 2D it will allow quick validation, manipulation abilities.
  • Provides the ability to visualize, video, track, and associated ranking.
  • Ability to provide input as sequence of images or a video file.
  • Provides the ability to manipulate track data. User should be able to insert a new one, modify the existing one.
  • Provides the ability to select a region with pixel level accuracy and draw a track on top of it.
  • Provides the ability to play many video files (small or large video) files.
  • Provides a layout for the videos in space so that each can be seen clearly for a view point.
  • Allows the videos to play individually or globally.1
  • Provides the ability to toggle different layers of information.
  • Provides geo spatial context.

Design

This is a graph with borders and nodes. Maybe there is an Imagemap used so the nodes may be linking to some Pages.


class vtkVideoElementRepresentation { public:

 void AddTrackRepresentation(vtkTrackRepresentation* tr); 
 void AddVideoRepresentation(vtkVideoRepresentation* vr); 
 void AddTrackRepresentation(vtkScalarRepresentation* sr); 
 
 virtual void PrepareToRendering();

private:

Internal* Implementation; };
