Hi Charles,<br>
<br>
The markup for polar works the same as the cartesian. Each sign is
written on its own canvas (or grid). Each canvas has a defined
center. The relative position of the symbols to each other is
determined by the writer. The position of the sign as a whole on its
canvas is determined by centering rules.<br>
<br>
Each markup will use 3 letters to represent lanes: L, B, and R. L for
a left lane sign box. B for a middle lane sign box. R for a right
lane sign box. Each of these letters signifies the start of a new
canvas. Consider the example I included:<br>
<br>
B<img alt="" src="cid:part1.02040701.04080202@signpuddle.net">330°16<img
alt="" src="cid:part2.01030904.08030800@signpuddle.net">129°14 B<img
alt="" src="cid:part3.09030902.09090708@signpuddle.net">169°21<img
alt="" src="cid:part4.03010000.02030806@signpuddle.net">252°6<img
alt="" src="cid:part5.03060202.02040504@signpuddle.net">80°11<img
alt="" src="cid:part6.07010300.06090704@signpuddle.net">19°21<br>
<br>
There are 2 signs, both in the middle lane. To use different lanes,
change the B's for L's or R's. Such as...<br>
<br>
L<img alt="" src="cid:part1.02040701.04080202@signpuddle.net">330°16<img
alt="" src="cid:part2.01030904.08030800@signpuddle.net">129°14 R<img
alt="" src="cid:part3.09030902.09090708@signpuddle.net">169°21<img
alt="" src="cid:part4.03010000.02030806@signpuddle.net">252°6<img
alt="" src="cid:part5.03060202.02040504@signpuddle.net">80°11<img
alt="" src="cid:part6.07010300.06090704@signpuddle.net">19°21<br>
<br>
The first sign is now in the left lane. The second sign is now in the
right lane.<br>
<br>
Both polar and cartesian coordinates are equivalent forms and represent
the exact same data from a different point of view. <br>
<br>
In my opinion, the cartesian markup is much easier to use. The polar
markup requires the use of trigonometric functions and the Pythagorean
theorem.<br>
<br>
It will take experimentation to determine if one markup is more
meaningful or useful as a whole.<br>
<br>

<div>But how would one show lanes in a polar writing. If one needs
multiple lanes to show a sign, say in the name sign Carmen Miranda, is
it the center of the sign or the center of the sign component that one
is showing. Just trying to make sure I understand cartesian vs polar.
Is this is terms of the whole map of the objects in a sign, or each
individual sign in a defined grid. Is this like Hangul in which a
construction method is being used to show where all the components are
in relation to each other, or in relation to an invisible box. </div>

Would not the polar version make it easier to change size - just one
parameter to change (distance), not all as in Cartesian?<br>

Hi Adam,<br>
<br>
Unfortunately, it's a 2 step process right now.<br>
<br>
The first page converts BSW 2008 to BSW 2010:<br>
<span><a moz-do-not-send="true" target="_blank"
href="http://signbank.org/iswa_dev/convert/example.php">http://signbank.org/iswa_dev/convert/example.php</a></span><br>
<br>
The second page converts BSW 2010 to BSW 3:<br>
<span><a moz-do-not-send="true" target="_blank"
href="http://signbank.org/iswa_dev/convert/bsw3.php">http://signbank.org/iswa_dev/convert/bsw3.php</a></span><br>
<br>
Section 4 of the conversion document links to both pages.<br>
<span><a moz-do-not-send="true" target="_blank"

<br>
<br>
Speaking of conversions, building on the idea of encoding the symbols,
but not the layout, I've created 2 different markups that will be able
to use my proposed Unicode implementation. One Cartesian and the other
Polar. These markups can be created from any SignPuddle data. <br>
<br>
If we consider "Hello world." in ASL...<br>
<img alt="" src="cid:part13.02010001.02040506@signpuddle.net"><br>
<br>
<br>
The Cartesian markup uses XY coordinates, where the coordinates
represent the top,left of the symbol position.<br>

<br>
<br>
The Polar markup uses degrees and distance from the center of the sign,
where the coordinates represent the center of the symbol position. 12
o'clock is 0° and increases clockwise. So 3 o'clock is 90°, 6 o'clock
is 180, and 9 o'clock is 270. It may be very interesting to analyze
the Polar markup.<br>
