3D Visualization

3D Visualization is a technique for creating images, diagrams, or animations to communicate a message in 3D. 3D enhances the illusion of depth perception. When 3D data is visualized the data often looks great when it is static. However when interaction with the data is required, the resolution and frame rate often drops to a level that gives users a headache.  A true lifelike experience presents the user with images that he or she believes, does not cause strain, or start breaking up while interacting with the data.  A true lifelike experience should be smooth, believable and a user should intuitively know what to do.  

PS-Tech believes that for 3D visualization the following is required:

  • A good 3D display
  • A correct position to look at the display
  • 3D images that are presented around the pane of the screen
  • No blocking of the Image during interaction (when “touching” the image)
  • Live rendering of 3D volumetric data

3D Visualization and its issues

Blocking image with hands during interaction

Without a good display, it will be impossible to create a true lifelike experience. The optimal 3D image on a display is created around the pane of the screen. Users have a tendency to extract images out of the 3D display for an optimal view. Especially when they want to interact with the image and “touch” the data. If you want to touch the image when it is optimally rendered at the pane, you can’t do this because the physical screen is there.  


3D Visualization and its advantages

3D rendering has changed the dynamics of architectural and engineering industries for the better. 3D visualization enables users to understand projects and data better and take the guesswork out of the analyses of 2D images. Our users, spread out over different industries such as medical and industrial design, indicate that getting the overview, understanding how one part is related to the other adds enormous value. Combined with the tools to work with this 3D data in a efficient and intuitive manner helps to unleash the full potential of this often complex data.

3D visualization and interaction without barriers

PS-Tech's C-Station and PSS are examples of 3D visualization workstations that solve the intrinsic problems of interaction with 3D screens.

Not only are they equipped with a good display, the design of these systems ensure that:

  • The user automatically has a correct position to look at the display
  • The quality of the 3D images are optimized because they are presented around the pane of the screen 
  • There is no blocking of the Image during interaction (when “touching” the image) 





The software package Vesalius3D further allows for two handed interaction and live rendering of volumetric data.
