1. Redhat Linux
8.0 :
NVidia Linux Drivers:
Once the basic Redhat install was complete we downloaded and installed the
drivers for the graphics board from NVidia's website. The NVIDIA Accelerated
Linux Driver Set brings both accelerated 2D functionality and high performance
OpenGL support to Linux x86 with the use of NVIDIA graphics processing units
(GPUs). These drivers provide optimized hardware acceleration of OpenGL
applications via a direct-rendering X Server and support nearly all NVIDIA
graphics chips.
XFree86 4.0.3 Configuration: After the NVidia kernel driver was installed
we had to make some changes to the x server's configuration file. Take a
look at /etc/X11/XF86Config-4 ( -4 is standard for xfree86 4.0.x). Follow
the directions included in the README file with the NVidia glx driver to
modify the x config file. It involves simply changing the driver from 'NV'
to 'NVidia' and altering a few of the other includes. We took a look at the
TWINVIEW_README file from the same dir to see how to enable the twin view
option and setup the second monitor. This is the config file.

Building the NVIDIA Driver: Installing the rpm files
$ rpmbuild –rebuild NVIDIA_k*
$ rpm –ivh /usr/src/redhat/RPMS/i386/NVIDIA_kernel-1.0-3123.i386.rpm
$ ls
$ rpmbuild –rebuild NVIDIA_GLX-1.0.-3123.i386.rpm
$ rpm –ivh /usr/src/redhat/RPMS/i386/NVIDIA_GLX-1.0-3123.i386.rpm
XF86 : Copied the XF86 config file into XF86 config.twinview for the projectors
and XF86 config.single for single monitor
The XFree86 configuration file is usually found in
/etc/X11/XF86Config. This section describes the parts, which must be specially
set for the DRI. Backup the file you want to edit. This is done with the
copy command, cp. Give the file an extension, which will let you know that
it is the original file. In this case
cp XF86Config.twinview
cp XF86Config.single3
To edit type vi Xf86Config.twinview and press Enter.
Editing the Config File:
· Driver “nv” with Driver “nvidia”
· In the Module Section make sure to have Load “glx” and remove the
following lines: Load “dri” and Load “Glcore”
Troubleshooting:
Problem: Low frame rate
when viewing 3D models
Solution:
Execute the command:
$ glxinfo | grep vendor
The output should look like this:
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation
If ‘NVIDIA Corporation’ is not listed, or you receive an error message
(such as ‘unresolved symbol’), you are not using the NVIDIA OpenGL libraries
and need to set the LD_LIBRARY_PATH environment variable to list /usr/lib
before /usr/local/lib.
2.0 Viewer:
Version : 0.7.3
URL : http://www-users.cs.umn.edu/~wburdick/geowall/viewer.html
Description: Viewer is an
OpenGL based stereo pair viewer and aligner.
At present it only accepts images in the PPM image format but work is in
progress to allow use of other image types. Viewer is known to work on many
systems, including Linux and OSL, but will work on anything with OpenGL
and a compiler. Besides being useful as a stereo pair viewer it is also
useful to view a mono image and easily pan/drag around with the image.
Building Viewer:
Installing the binary:
Tar – xvzf viewer-0.7.3-linux-x86-binary.tar.gz
$ cd viewer-0.7.3
$ tar –xzvf viewer-0.7.3
Installing Viewer from source
:
$ tar –xzvf viewer-0.7.3.tar.gz
$ cd viewer-0.7.3
$ ./configure –prefix=$INSTALLDIR
$ make
$ make install
Usage:
viewer [basename]
----will read basename-l.ppm (LEFT EYE IMAGE FILE) and basename-r.ppm (RIGHT
EYE IMAGE FILE) as left and right images and will write basename-leftcrop.ppm,
basename-rightcrop.ppm, and basename-pair.ppm
viewer [options]
-i leftinfile.ppm rightinfile.ppm
-v fullinfile.ppm
-o fulloutfile.ppm [default = fullout.ppm]
-l leftoutfile.ppm [default = leftout.ppm]
-r rightoutfile.ppm [default = rightout.ppm]
Must contain either the -i or -v options or only basename. If the -o, -l,
or -r options are omitted default will be used
3.0 ImmersaView:
http://www.evl.uic.edu/cavern/agave/immersaview
Can be used to View .iv formate files an VRML (1.0 and 2.0) formate
files.

ImmersaView is an Open Inventor model viewer for the GeoWall/AGAVE. The
data can be a single Inventor model or a flipbook of models that you can animate
or single-step through. This software uses Coin3D and fltk, used to compile
ImmersaView from scratch. ImmersaView is currently supported in the Linux,
Windows and Macintosh environments.
Compiling Immersaview:
1. You should install the Coin3d and simage libraries (http://www.coin3d.org)
and the fltk library (http://www.fltk.org) before compiling Immersaview.
2. Change directory to immersaviewsrc. Open 'Makefile' and edit the variablesINVENTOR_LIB,
INVENTOR_INC, FLTK_LIB and FLTK_INC to point to the correct directories.
3. The default compiler is g++.
4. Type 'make'.
5. Add the Coin and simage libraries to your path before you run immersaview
(if they are not in the path already) i.e. set the LD_LIBRARY_PATH variable
as follows: exportLD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/cavern/Coin3d/lib
oin3D: Coin is a high-level 3D graphics library with a C++ Application Programming
Interface. Coin uses scene graph data structures to render real-time graphics
suitable for mostly all kinds of scientific and engineering visualization
applications. Coin is portable over a wide range of platforms: any UNIX
/ Linux / *BSD platform, all Microsoft Windows operating system, and Mac
OS X. Coin is built on the industry-standard OpenGL immediate mode rendering
library, and adds abstractions for higher-level primitives, provides 3D
interactivity, immensely increases programmer convenience and productivity,
and contains many complex optimization features for fast rendering that
are transparent for the application programmer.
4.0 How to load
your own Open Inventor models: The scripts RUN_HEART
and RUN_QUAKES execute 'immersaview'. You have to provide the model as the
first argument to this executable. The second argument can be a configuration
file (default : StereoCameras.iv).
A] Loading a single model
1. Suppose you have a model called 'Earth.iv'. Create a script RUN_EARTH
in your favorite editor.
2. Type './immersaview Earth.iv'. Save and exit.
3. Now run 'RUN_EARTH'.
Coin is based on the SGI Open Inventor API. Open Inventor, is the de facto
standard graphics library for 3D visualization and visual simulation software
in the scientific and engineering community
FLTK: FLTK (pronounced "fulltick")
is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®,
and MacOS® X. FLTK provides modern GUI functionality without the bloat and
supports 3D graphics via OpenGL® and its built-in GLUT emulation. FLTK is
designed to be small and modular enough to be statically linked - the "hello"
program is only 97k when compiled on an x86 Linux system! FLTK also works
fine as a shared library and is now being included on Linux distributions.
FLTK also includes an excellent UI builder called FLUID that can be used
to create applications in minutes.
6.0 Downloaded new software DIME:
URL: http://www.coin3d.org/Dime/about.php
Dime is a C++ class library for reading, constructing, manipulating, and
writing DXF file data. The name is an acronym for DXF Import, Manipulation,
and Export library. Dime is known to compile on Win32, Linux, IRIX, HP-UX,
Solaris, BeOS and MacOS. Converts dxf to VRML files.
7.0 NETPBM
netpbm is a package of graphics manipulation
programs and libraries.
We installed the following rpm packages form redhat
Distribution CDs
netpbm-devel-9.24-6.rpm
netpbm-progs-9.24-6.rpm
netpbm-9.24-6.rpm
Netpbm is a package of graphics programs and programming libraries.
There are over 220 separate programs in the package, most of which
have
"pbm", "pgm", "ppm", or "pnm" in their names. For example, pnmscale
and giftopnm.
For VIEWER we need .ppm format files. Netpbm can be used to convert jepf
