the keyboard or a combinaton.
Here're the basics
| tripple-click object in "browse mode" | smoothly fly to the object |
| pressing mouse-botton over object | open the corresponding page in a standard browser |
| click, click-hold in "rearange mode": | drag around object in 3D (horizontal planes only) |
|
click in "delete mode" |
delete page or mother plattform and all its children |
| drag mouse on white background | walk |
| ALT+Drag | move up/down and step sideways |
| Ctrl+J | force jump-mode |
For a complete coverage also look up the blaxxun help
enter a searchterms (boolean "+" "-" are also evaluated) or a direct ULR starting with "http://" to create a new platform
toggle "browse", "rearange" and "delete"- mode with the corresponding switches
toogle the mapping of found gifs an jpgs for future actions by activating the checkboxes
look for information on the URLs and the options you got in the two info-lines.

frequently asked questions
problems getting it running
Q:
I have a blank screen coming up - what's wrong?
A: You don't seem have a blaxxun-plugin, please
follow the installation-guide
Q: In my java console it
reads "JavaSecurityException": are you trying to crash my system?
A: No!!! In order to get html-pages from other locations
displayed we need to step out of the "java sandbox", which in
general is a useful way to protect your machine from bad applets. We don't
do such things Please disable the corresponding security feature in your
browser for as long as you run webray.
Q: a blue platform is displayed
when I hit the go button - but that's it.
A: Please have look in
your java console, in most cases it will be a security-related
problem
Q: I'm sick of loading the 1.3
MB, is a smaller version of webray available?
A: Yes there is. But it's
equiped with an ugly standard AWT-GUI. Here's the pro: its only 135 kb!
Start the small version here.
performance related
Q:
Oh my god - this thing is slow! Is there anything I can do to increase
performance?
A: Either try to tweak
your VRML-Browser (go
here to learn how) or toggle the "get gifs" and "get
jpg" options of, this will reduce both graphic-pipe and network-load.
The most simple solution is to delete unneeded objetc (->deletemode->click
on objects). Also you can disable MipMapping, nice transparency and smooth
textures in the blaxxun-context menu
Q:
my networkoad monitor is bursting! What to do?
A: toggle of the gif&jpg-options,
this hinders webray from getting the textures, that can be very big

the pictures mapped look creepy, can I increase the quality?
A: right-click in the browser menu, choose settings and enable
Mip-Mapping, smooth texturing and nice transparency
