var floatimages=new Array();
floatimages[0]='cloud14.gif';
floatimages[1]='sunan2.gif';
floatimages[2]='tornado5.gif';

I 'borrowed' this floating image script.
But I would like to be able to select which of the images are floating
around.

I know I could just 'cut' the lines but I probably will want to change them
back and forth.

So is there a way to REM out a line like in the 'ahem' old days when I
actually had an idea of what I was doing????
 
REM, now that brings back memories :-) In javascript it's // eg
// floatimages[0]='cloud14.gif'; - this will be ignored
 
thank you, that did it.
Got to find a book that has these type of answers.

Well, for example, there are entire books on JavaScript online. In fact, I
recently found an entire SET of books on calculus, which I've been having to
teach myself lately, for the work I'm doing.

So, Murray, how do you mathematically tell in what direction an aircraft is
rolling without a gyroscope, only an attitude indicator? I'm killing myself
trying to figure it out!

If the attitude indicator says nose up and speed is increasing then
the plane is rolling backwards. Speed decreasing: forwards.

That defies the physics of flight. Airplanes don't roll frontward and backward. They pitch.
The lateral axis, ( wingtip to wingtip ) rolls around the horizontal axis.
The horizontal axis ( nose to tail ) pitches around the lateral axis.
They yaw around the vertical axis ( perpendicular to both the lateral axis and the horizontal axis )

LOL. I was thinking that Kevin meant rolling along on the ground.

For a roll while airborne it's even easier. If the attitude indicator
spins clockwise the plane is rolling counter-clockwise, and vice
versa.

Mathematically, if dA/dt>0 where A is the angle from any fixed line
perpenducular to the plane's nose-tail axis to the current position of
the left wing, and positive angles are measured clockwise, then the
plane is rolling clockwise.

Duncan
 
Well, I didn't mention that I'm not actually using an attitude indicator,
only GPS readings, which give the current state of the plane. So I can only
know what it's roll was 1 second ago and now. The problem is, which way is
it rolling? Since distance = rate * time, and the distance is either an
angle OR 360 minus the angle, I can't compute it. I know the time, but the
distance (difference in angle) is one of 2 possible values! In other words,
the plane could be in a very fast roll, or a slow one. Currently I'm using
the lesser of the 2, but of course that is problematic if the plane DOES go
into a fast roll. What I'm trying to do is interpolate my animation between
reads.

I see. Set a fast sampling rate. Then assume that if the plane rolls
more than 180 deg between samples that the wings will come off. Then
you don't care what direction the roll was going, and you don't have
to interpolate any more. ;-)

Duncan
 
You guys are doing it the hard way...just calculate the amount of beer spilled and in which direction.
 
Actually the attitude indicator ( or "globe" ) remains stationary and the airplane rolls, pitches or
yaws around it.

The term you are looking for is AHRS or Attitude Heading Reference System.
The "globe" inside of the AHRS remains stationary and the indices you see on the face of the AHRS
move around the "globe" relative to the movement of the aircraft, because the indices are "fixed" to
the structure of the aircraft.

Compute the roll rate using a circle whose diameter is equal to the wingspan.
In other words measure the roll rate at the wingtips.
In a perfect "horizontal roll" ( which must be performed at zero G ) each wing tip makes a perfect
360 circle as the plane rolls around the horizontal axis.

In a coordinated roll ( a roll always maintaining 1 positive G on the airplane ) the wingtips still
make a 360 degree circle, but the
plane does not roll around the horizontal axis, but actually "spirals" as it rolls.

In a well executed coordinated roll, you can set a glass of water on the instrument panel and never
spill a drop.

Doesn't work with water because beer has different specific gravity.
