This project uses the pyTUIO library to obtain multitouch information that is then used to interact with a VTK session.
The Main.py script will launch the VTK GUI session seen above. This session will act as our Demo launcher. Using one finger will rotate the scene.
Two fingers will allow the user to select an object with the second finger. Hovering over the main sphere will display four additional spheres.
Selecting any of these spheres will automatically close the current VTK session and launch a different demo.
Each demo creates an instance of CursorTracker located in MultiTouch.py. The CursorTracker object will maintain a dictionary of each recorded finger/cursor
and it's start, previous, and current positions. Each demo uses this information to create gestures like pinch zooming, rotating, and panning.
Displays a sagital view of the head. The scene can only be rotated along its x axis.
IMPORTANT
Make sure to pass the correct path to the /headsq directory as an arguement to the vtkVolume16Reader method SetFilePrefix().
This example reads a volume dataset, extracts two isosurfaces that represent the skin and bone, creates three orthogonal planes
(sagittal, axial, coronal), and displays them.
IMPORTANT
Make sure to pass the correct path to the /headsq directory as an arguement to the vtkVolume16Reader method SetFilePrefix().
TestDemo.py is a used to verify that TUIO events are being properly received and tracked. A small number will be used to represent cursors.
Rotate: 1 finger swipe
Zoom In: 2 finger reverse pinch
Zoom Out: 2 finger pinch
Pan: Requires 3 fingers. 3rd finger position is used to translate image
Close Demo: 4 fingers
