Introduction
ImmersaView is an Open Inventor and VRML2 model viewer for the GeoWall/AGAVE. The data can be a single Inventor/VRML model or a flipbook of models that you can animate or single-step through.  This software uses Coin3D and glut.  Make sure that you are using Coin version 2.3.0 or greater.  Collaboration is supported by the QUANTA toolkit. You do not need to download them yet. You only need them if you intend to compile ImmersaView from scratch.  ImmersaView is currently supported in the Linux,Windows and Macintosh environment. Click on the OS that you are interested in to download Immersaview.  For more detailed information about using Immersaview, please visit the Immersaview website.

Before Running Immersaview

Make sure that you have GLUT and Coin3D available on your machine and installed properly.  If you are compiling Immersaview, make sure that you have QUANTA installed and then click the name of your platform which will link to the appropriate compile information: Windows, Mac OS, Linux.


If you are running immersaview on either Mac OS or Linux, running immersaview has changed from previous versions.  In order for immersaview to run properly, make sure that the shell scripts named remove-symbolic-links and make-symbolic-links is run in that order before immersaview actually runs.  This will remove and make links to StereoCameras.iv and immersaview to each subdirectory in the data directory, respectively.  Without performing this step, immersaview will not run.



Running Immersaview
Overall, running immersaview is more complicated in the past, so it is strongly encouraged that as you build your data directory, take the time to make a batch file or shell script that will save you time from having to type the following lines each time you want to run immersaview.  If you are using Windows, type the following to run immersaview:


cd data\dataDirectoryName
..\bin\immersaview.exe sceneFile.iv ..\configFiles\StereoCameras.iv


On Linux and Mac OS, the use of symbolic links to immersaview and StereoCameras.iv somewhat simplifies things.   Once you have created the symbolic links as described in the previous section, type the following:


cd data/dataDirectoryName
./immersaview.exe sceneFile.iv StereoCameras.iv

Try executing RUNquakes (on Windows,  run the files with the .bat ending; on Linux and Mac, run the scripts as they appear here).   If you have a stereo setup in the configuration file, then you should see immersaview appear in the following way.



If you are interested in making your own data directories, all that you have to do is follow some simple steps.  First, make a subdirectory in the data directory with the name of your model.  Second, copy all of the .iv files into that directory.  Next, if you are using Mac OS or Linux, return to the base immersaview directory and run the script named make-symbolic-links.  Finally, make a script that will change to your model directory and then run immersaview in the manner described above (look at RUNheart or RUNheart.bat for an example).

User Interface Controls

Using the mouse...

To rotate the model:
Click on the 3-D model with the left button. Drag the mouse to rotate the model in the direction you want.

To zoom in and out of the model:
Click on the model with the middle button. Drag the mouse into the screen to push the model further and towards you to bring the model closer.

To move the model sideways:
Click and hold on the model with the right button. As you drag the mouse, the model should follow you and rest wherever you release the right button.
