VRML/2 v1.0 - Doc
-----------------
Welcome to VRML/2 v1.0.
This file contains information you need to install VRML/2.
This README file is divided into the following categories:
- Keyboard commands
- Navigation
- Drag and drop
- Netscape (helper app)
- Trouble shooting
Keyboard commands:
------------------
SPACE activate link (anchor) under mouse pointer
PAGE_UP look down
PAGE_DOWN look up
+/- zoom in/out
I look down
J,K turn left/right
M look up
A move forward
Z move backward
CNTRL-r register
Navigation:
-----------
To navigate in VRML/2 you use the two mouse buttons along with the current
state of the mouse pointer. When the mouse is positioned over different areas
of the display screen you will find that the pointer will change to indicate
what kind of movement is to be preformed. Once the left mouse button (LMB) is
pressed that movement will continue until the LMB is released or the mouse
pointer is move to a new position. The right mouse button (RMB) can also be
used in this way but instead of the viewer moving, the scene (or object) will
rotate about itself (spin). At any time you can press the camera button to
auto focus if you get lost.
Step Size - the size of the step or speed that you will travel at is set to a
best guess by VRML/2. If you which to slow down or speed up your movement just
click on the bottom right spin button and adjust to your desired rate.
Turn Rate - the turn rate is also adjustable in the same way. Simply click on
the spin button on the right (second from the bottom) and set the rate as
desired. NOTE: that the numbers represent 1/10th of a degree so if you have
a value of 90 would be 9 degrees not 90.
Drag and drop:
--------------
So far VRML/2 does almost all the basic drag and drop functions. The main
function not supported at this time is the ability to drag a URL from the
main viewing screen to your desktop.
VRML/2 comes with a folder called 'WRL' that contains two VRML files. Thease
files can be dropped onto the main viewing screen.
With VRML/2 you can drag fonts and colors to most anything including your
background color for the scene. All colors will be kept from session to
seesion with the exception of the scene background.
Netscape (helper app):
----------------------
VRML/2 can take a URL name as a parameter when it starts up. This allows you
to setup VRML/2 as a helper application for you main web browser. Below are
instructions for setting VRML/2 up to be used with Netscape.
1) Start Netscape.
2) Click on 'Options'.
3) Click on 'General preferences'
4) Find the 'Helpers' tab and click on it.
5) Hit the button 'Create New Type'.
6) For 'Mime Type' enter: x-world
7) For 'Mime Sub Type' enter: x-vrml
8) Push the button 'Launch the Application'
9) Push 'Browse' and find VRML2.exe which is installed in the main directory
for VRML2 (default c:\VRML2).
Now when your browser trys to load a VRML file VRML/2 will be started with
the file already loaded.
Trouble shooting:
-----------------
Error Log - VRML/2 will make a log of all the errors it encounters in
the main VRML/2 directory. The file is called 'error.log' and
the format is simply text with english messages. Note that this
file is never erased. The error log is also time stamped plus it
has a divider bar that indicates a different session.
General problems- Do you have OpenGL installed? Make sure you have the
following files installed in your LIB path.
109354 0 glut.dll
48256 61 libaux.dll
147962 61 libtk.dll
513671 61 opengl.dll
4133738 61 raster.dll
- Check the hardware and software requirements found in the
read.me file.
Unreadable file format - the file is not a VRML 1.x file or the file is
compressed and VRML/2 is not registered.
Invalid header - The file your trying to read is most likely not a VRML 1.x
file. Load the file ina text editor and check the first line for
'#VRML V1.0 ascii' or '#VRML V1.1 ascii'. This must be exact or the
file won't load.
- The file could be compressed (gzip). Thease files are only
readable for registered copies. You know the file is compressed if
you get garbage when you try to load it in a text editor.
