AVRIL

This is release 2.0 of AVRIL, a library for creating virtual reality
applications.

Changes since 1.1 include:
HMD support:
CyberMaxx (VictorMaxx Technologies)
i-glasses! (Virtual i/o)
7th Sense (All-Pro)
support for CyberWand from InWorld VR
support for the FifthGlove from 5DT
stereoscopic viewing
Gouraud shading
modular video driver
modular display driver

These changes are detailed in Appendix A of the documentation file.

Unfortunately, there are some features that are not fully implemented.

The Gouraud shading has a few flaws (little glitches here and there
in the shading), and hasn't been exhaustively tested; it's the last
feature I added before the release. It's also very slow; using a
little bit of assembly language here should speed it up considerably,
but I'll save that for the next release.

Not all the stereo modes are implemented yet.

The horizon code was always broken, so I've temporarily
disabled it; I hope to completely rewrite it for a future
release, adding a "stepped" or "layered" horizon; if anyone
has any code for doing this that they'd like to contribute,
let me know!

The current version of the code is also relatively slow, since I've
converted everything to C (no assembly language at all) and haven't done
any optimization. This is the final stage before porting to other
platforms; once the ports have been done, I'll be re-optimizing the PC
version and putting assembler into a few time-critical routines (thereby
getting the speed back up).

The latest version of this software can always be found on sunee.uwaterloo.ca,
in the pub/avril directory.

USING AV

Unzip sample.zip, using the -d option to create a directory for the sample
world. In other words, type "unzip -d sample".

To run AV, just type "av sample.wld". You can also view individual PLG
files and FIG files using AV.

MOVING AROUND

Moving around the virtual environment is easy. The following applies to AV
or any of the example programs (once they've been compiled).

Key Function

up/down arrows move forward/backward
left/right arrows turn left/right
leftshift plus up/down arrows move up/down
leftshift plus left/right arrows move left/right
rightshift plus up/down arrows look up/down
rightshift plus left/right arrows tilt head left/right

OTHER KEYS

The following keys perform various functions:

ESC quit
f toggle frame rate display
c toggle compass display
p toggle position display
d toggle display of debugging information
_ (underscore) toggle horizon off/on
+,- zoom in, out
= reset zoom
h,H adjust hither clipping plane distance by current space step
w toggle wireframe mode
(space) toggle mouse mode between 6D input and on-screen selection
