Stereoscopic (3D) Projection

LTC in RCS1 is equipped with a stereoscopic projector configuration used with polarized glasses stored at the front of the room, which allow viewing of 3D images and video.

To start, select both projectors from the lectern’s control panel by first selecting the PC as the output and then selecting “Enable 3D”.

In order to view the output, the applications that will be used to display 3D content must be set up to use the Quad-Buffer OpenGL viewing method.

Testing Stereo projection

Download Stereoscopic Player: http://www.3dtv.at/Downloads/Index_en.aspx
To play sample stereo videos, install http://www.microsoft.com/windows/windowsmedia/player/11/default.aspx)
Get a stereo jpg: http://www.chasm.com/images.htm
Install the Stereoscopic Player, open truck.jpg, and choose side-by-side, left eye first for the image format.
In the View menu, change the stereo view method to OpenGl quad-buffer stereo.

Discovery Studio (DS)

Discovery Studio is a comprehensive software suite for analyzing and modelling molecular structures, sequences, and other data of relevance to life science researchers. The product includes functionality for viewing and editing data along with tools for performing basic data analysis.

This application is already setup to output via the default setting of the graphics adapter. Please ensure that:

• Hardware Stereo Type is selected in the Molecule Window section of the program preferences as shown below (Click Edit and then Preferences):

• There is a tick in the Stereo option in the View menu as below.

ChemBio3D

ChemBio3D is a powerful desktop modelling program that enables synthetic chemists and biologists to generate 3D models of small molecules and biochemical compounds. To access the ChemBio3D program settings, click on File, then Preferences to display the options on the right. Ensure that the Use Back Buffer for Refresh checkbox is ticked, then click Apply and then OK (see below):

VMD

VMD is a molecular visualization program for displaying, animating, and analyzing large bio molecular systems using 3-D graphics. Pleaseuse the display settings shown in the image below to render output via the 3D projector:

CCDC Mercury

This is a component of the Cambridge Structural Database System (CSD System) which provides a range of tools for 3D structure visualization, the exploration of crystal packing and the statistical analysis of CSD search data.

To access the Mercury program display settings, click the top menu and select Display/Display options/Stereo. Ensure hardware stereo is enabled (see below):

To set the 3D effect to emerge out of the screen, set the focal point to a +ve value. Adjustments can also be made with the Separation to create the optimal effect.

Knotplot

This programs allows 3D visualization of an enormous variety of knots and other topological objects. To initialise stereo, the program has to be started from the command line rather than the more usual start menu or application double click. A shortcut which invokes this flag is available on the desktop.

cmd: knotplot -stereo

Stereoscopic Player

Stereoscopic Player is a 3D movie and stereo JPEG player. It allows you to play stereoscopic videos and DVDs (external decoder required) and also allows you to watch live video from a capture device. It can handle most media formats, for example AVI, MPEG, WMV, ASF and MOV. Videos can be coded in several different stereoscopic formats.

Please use the display settings shown in the image below to render output from Stereoscopic player via the 3D projector.

MIPAV Medical images

The MIPAV (Medical Image Processing, Analysis, and Visualization) application enables quantitative analysis and visualization of medical images of numerous modalities such as PET, MRI, CT, or microscopy. Using MIPAV's standard user-interface and analysis tools, researchers at remote sites (via the internet) can easily share research data and analyses, thereby enhancing their ability to research, diagnose, monitor, and treat medical disorders.

Instructions for enabling Stereo.

After starting the application (Start > All Programs > MIPAV), you will see the following splash screen:

Followed by two windows as shown below:

Select Help > MIPAV Options. The MIPAV Options dialog box opens. Click on the Other tab and ensure that the GPU Computing enabled checkbox is ticked. If it is greyed out, there may be a problem with the graphics card, graphics driver or both and GPU volume rendering will not be possible.

To display an image series in S3D, open the image series first. Click File > Open image (A) from disk as shown below (Sample images were downloaded from http://www.cancerimagingarchive.net/ )
