Can I use software installed on Windows NT servers remotely (outside Windows NT lab)?

We Currently do not  provide terminal services, hence you can not use the software remotely. However, a few software are available, which you can install and use from your own PC. Please see on the tree menu on the left to find out.

type following commands on your xterm:
 

gnuplot

It will bring the following command prompt

How do I use OpenGL with GLUT

1. Get the following files:

glut.h put this file in homedir\bin\include\gl (make the necessary directories)

glut32.dll Put this file in your homedir\bin

glut32.lib Put this file in homedir\bin\lib

2. Modify PATH variable

Open start_menu -> settings -> control_panel -> system ->environment tab. Look for a variable called PATH (or Path or path) in the LOWER TEXT BOX (MARKED AS: User Variables for ...). If there is such a varable defined click on it. Add the path to the 'Bin' directory in the value field. 'Path'
in Windows are separated by ";" (in unix they are separated by ":"). e.g. your path field after change may look like
.;z:\cse\bt\dbera\bin click on 'Set'. Verify that it has been changed. Ok. Done this step.

If instead you see no variable called Path, click on the last blank line in the LOWER TEXT BOX. Then write 'Path' in the 'Variable' field and add the
path to your Bin directory  in the 'Value' field. Click on 'Set'. Verify that it has been added. Ok. Done this step.
 

3. Make necessary changes to Visual Studio options

Open Microsoft Visual Studio. Goto Tools_menu->Options->Directories tab
(somewhere to the right). Click on the drop down menu for 'Show directories
for'->'Include files'. (See figure below). Add the path to your 'Include' directory in the space below.

Similarly add the path to the 'Lib' directory .

(Add full path while adding paths.)

7. In the OpenGL source files, include

#include <Gl/glut.h>

in some downloaded example files, they may be <glut.h>, please change
them.
