Hi,
I need to implement a display very similar to google earth.
I need to display a slice cut from a large 3D volume, when user moves the slice (say x slice) within the volume, I will display the data coarsely (re-sample coarsely) so it gives the user a "quick" feeling.
However, when user stops moving the slice, I will need to display the slice in original sample so user will see a good quality of display.
How do I schedule an event or a thread to handle this? Or how do I know user have stopped moving the slice?
I am using Qt 4.7.3.
Many thanks!
