Tunnel 3d 1.1 - Copyright (C) by Fabio Ciucci 1997/98


This applet can generate a texturemapped tunnel from any GIF/JPG image.
Remember that are needed both tunnel.class , Lware.class and anfy.class.
You must upload these 3 .class files and insert the <applet> tag on your
html document to add this applet to your page.
This applet is fully parametrized, so you can generate all kinds of tunnels
you want. Here an example of what you have to write in the html (the
things anfter the ; are comments with min-max values acceptet):

                             ---------


Here detailed instructions about how to change parameters:


The credits parameter can't be changed otherwise the applet will not work.

To activate the reg parameters read the shareware registration notes.
In the "regcode" parameter you have to place the registration code you
purchase from the author. If it is correct and the applet is run from the
registered domain name, you can use "reglink" parameter, where you can specify
an URL where bring user when the applet is clicked.
If you set to "YES" regnewframe, you can specify a frame where load the
reglink:

"_blank"  : To load the link in a new blank unnamed browser window.
"_self"   : To load the link into the same window the applet occupies.
"_parent" : To load the link into the immediate FRAMESET parent.
"_top"    : To load the link into the top body of the window.

Otherwise the frame name, for example "myframe1".

The applet can be of any size. If res=1, remember to place the exact
size of image in "width" and "height" tags. If res=2, place double values,
if res=3 triple values etc.
In fact, res is a sort of zoomer.

The image used as texture can be of any size, but the preferred size is
256*256. Try to use images with a size close to this one, GIF or JPG.

REMEMBER to write the size of the texture image in the textw and texth
parameters!!!

The "tunnelradius" determine the size of tunnel.

You can change the lightning/shading of tunnel with lightmin, lightmax,
lightdec parameters.

Yes can disable/enable shading with the "shade" parameter, and invert the
shading with "lightinv".

You can enable a "square" mode, replacing the cilyndrical one, with the
parameter "squared".

The movements of tunnel are determined by "tunrot" and "tunadvance", and
the movements of observer are determined by "xrot","yrot","zrot".

You can enable interactive mode with "interactive" parameter: if set to
"yes" user will control tunnel movements with mouse.

You can enable the tunnel morphing function setting "bends" parameter to
"yes". You will control the bends with bendoffset, bendsizemin, bendsizemax,
bendoffsetinc, bendsizeinc.
