List Of Continents

2015-05-05T10:03:07Z

Ai Austin: /* Comparation to Earth */ typo correction

The Second Life main grid is composed of isolated sims (islands), groups of sims and continents.
A continent is a group of more then 30 sims (see [[Continent]] for more details). What doesn't match this definition is a [[Subcontinent]], a [[Microcontinent]], a [[Sim Group]] or a [[Sim Cluster]]. Other structures might be refered as [[Unassociated Sims]] or [[Isolated Sim]]. Different autors have found a different number of continents. It is also important to remember that every day about 20 new sims are created, moved or changed their names (see [http://www.gridsurvey.com] for more info). So, the shapes and even the numbers of continents might change in time.
An older map can be found at this link: [http://virtualchristine.com/newbie-sl-world-map/]

== Mainland continents ==

[[File:Continents Map.png|200px|thumb|right|Map of all continents]]

In alphabetic order, the Linden owned continents:

1. [[Corsica]]

2. [[Gaeta 1]]

3. [[Gaeta 5]]

4. [[Heterocera]]

5. [[Jeogeot]]

6. [[Nautilus]]

7. Premium East (see [[Premium Continents]])

8. Premium South 1

9. Premium south 2

10. Premium south 3

11. [[Sansara]]

12. [[Satori]]

13. [[Sharp Continent]]

14. [[Zindra]]

Notes:
#Nautilus and Satori are linked together and form a megacontinent (like Euroasia in real world).
#Blake Sea has more private-owned sims then mainland sims, so it was moved to private continents.
#There are private-owned sims in Eastern Sansara (Islands) and Nautilus (Seychelles).
#Many mainland continents are linked with a [[Transcontinental Channels]], like Sansara-Heterocera, Nautilus-Blake Sea, the two Corsica-Nautilus passages and Corsica-Gaeta 5.

These continents can be clasified in 3 distinct groups: ''1st generation'' (the oldest, with the most interesting Geographic features: Sansara, Heterocera and Sharp Continent), ''2nd generation'' (the group in East: Nautilus, Satori, Corsica and the 2 Gaetas) and ''3rd generation'' (Zindra and the Premium Continents). Jeogeot is something between generations 1 and 2.

== Private continents ==

In alphabetic order, these continents were identified in November 2013:

1. [[Blake Sea]]

2. [[Caledon - Winterfel]]

3. [[Eden]]

4. [[Estate Continent]]

5. [[Europe Continent]]

6. [[Fairchang]]

7. [[IGBC Continent]]

8. [[Mar Lesbiana]]

9. [[Seductive Microcontinent|Seductive]]

10. [[Shopping Continent]]

11. [[Uhre Continent]]

12. [[Wild West]]

Notes:
#Private continents sometimes have multiple names, depending on who made their maps.
#The private continents can be divided in two main groups: [[Tropical Beach Paradise]] (Blake Sea, Eden, Estate - only parts of it, Fairchang, Irish-Bonaire, IGBC, Mar Lesbiana) and '''not tropical''' (part of Estate Continent, Shopping Continent, Wild West, Uhre continent).
#Only Estate Continent, Shopping Continent and Wild West have a large piece of dryland, all the others are formed of sea and islands.

=== Vanished continents ===

'''No Access Continent''' existed until July 2013. It had the shape of a square with a void middle and had a large visible road. It had between 30 and 37 sims. Since access was restricted, no images from its surface and no surveys could be made.

[[Irish - Bonaire]] was a continent that existed until August 4th 2014. It broke into small pieces, being renamed ''Nonaire Sim Cluster'' and received designation name A231.

== Comparation to Earth ==

The position of Second Life mainland continents is a bit similar to that of the continents on Earth, but in mirror. The old world (Europe, Asia and Africa) form a group and the new world (the two Americas) form another block. [[Sansara]] and [[Heterocera]] form together a group and they are linked together with a tiny channel. They are in fact the old world of Second Life. [[Jeogeot]] is in South and was the third continent. It might be considered like Africa. The new world might be considered the [[Gaeta 1]], [[Nautilus]], [[Corsica]], [[Blake Sea]] and [[Satori]], only that they are in East, not in West. Satori looks a bit like South America and the South islands of Nautilus might look like Central America with its islands.

== Statistics ==

The following table shows size (in sims) and maximum height of each continent, in alphabetic order:

== Oceans ==

Many private sims are not linked in large groups to form a continent. The majority are isolated sims, while some of them form larger islands, with 2 to 29 sims. Even if they form important features on our map, the oceans containing these sims are not named in an official way. See [[Oceans]] for more info.

Groups of sims smaller then a continent are listed in [[List Of Microcontinents And Sim Clusters]].

HTML HUD Demo

2011-08-27T18:16:24Z

Ai Austin: Corrrect typo on Options" in LSL. Suggest a "Stop All Animations" button.

Suggest a "Stop All Animations" button be added to Animations selection frame for convenience.

<lsl>// HTML Based, Single Script HUD
// This is intended to be a tech demo of what html on a hud allows.
// * Interaction with SL world (give items, play animations, scan nearby avatars)
// * Simple, low overhead (1 scripts, 1 prim)
// * Rich, dynamic interface (images, menus, flash)
// Updates and improvements are welcome at http://wiki.secondlife.com/wiki/HTML_HUD_Demo

// To Use:
// * Create a cube and wear it as a hud on the top-left. (script will need tweaking for other spots)
// * Edit the cube while wearing it and add this script to it.
// * Add any animations you want to play to the object
// * Add any notecards or objects you want to give away to the object.

// License:

Ai Austin: /* Forms */ Corrected google.com search URL to search?q= rather than ?search=

== Shared Media and HTTP-In ==
Pre-Viewer 2.0 interfacing with an LSL script is a jumble of llDialog, chats, touches and possibly external web sites. With Shared Media that all changes.

One step at a time .......
=== llSetPrimMediaParams ===
* Use llSetPrimMediaParams to set the url and various parameters on the face of a prim via LSL.
<lsl>
default
{
state_entry()
{
llSetPrimMediaParams(0, // Side to display the media on.
[PRIM_MEDIA_AUTO_PLAY,TRUE, // Show this page immediately
PRIM_MEDIA_CURRENT_URL,"http://google.com", // The url currently showing
PRIM_MEDIA_HOME_URL,"http://google.com", // The url if they hit 'home'
PRIM_MEDIA_HEIGHT_PIXELS,512, // Height/width of media texture will be
PRIM_MEDIA_WIDTH_PIXELS,512]); // rounded up to nearest power of 2.
}
}
</lsl>

=== data: urls ===
There is a special url type: "data:" that lets you send the html ''in the url''. Paste the below into your browser's address bar.
<pre>
data:text/html,<h1>This is a test</h1><h2>This is a test</h2><h3>This is a test</h3>
</pre>

=== llSetPrimMediaParams for data: urls ===
* Thus you can build arbitrary html in your LSL script and display it on the face of the prim
<lsl>
show(string html)
{
html = "data:text/html," + llEscapeURL(html);
llSetPrimMediaParams(0, // Side to display the media on.
[PRIM_MEDIA_AUTO_PLAY,TRUE, // Show this page immediately
PRIM_MEDIA_CURRENT_URL,html, // The url currently showing
PRIM_MEDIA_HOME_URL,html, // The url if they hit 'home'
PRIM_MEDIA_HEIGHT_PIXELS,512, // Height/width of media texture will be
PRIM_MEDIA_WIDTH_PIXELS,512]); // rounded up to nearest power of 2.
}
default
{
state_entry()
{
show("<h1>This is a test</h1><h2>This is a test</h2><h3>This is a test</h3>");
}
}
</lsl>

=== HTTP-In ===
* Scripts can become web servers via HTTP-In
<lsl>
default

=== Forms ===
* You can put forms in data: urls
<pre>
data:text/html,<form action="http://google.com/search" method="GET">Search:<input type="text" name="q"><input type="submit" value="Submit"></form>
</pre>

=== The Magic ===
* You can set the script HTTP-In url as the form action to get the results of the form sent back to the script
<lsl>
string html_base =
"<h1><form action='%url%' method='GET'>
Floating Text:<input type='text' name='text'><br>
<input type='submit' value='Set'>
</form></h1>";

string url;

integer r;
show(string html)
{
html = "data:text/html," + llEscapeURL(html) + "<span " + (string)((++r) % 10) + "/>";

llSetPrimMediaParams(0, // Side to display the media on.

PRIM_MEDIA_CURRENT_URL,html, // The url currently showing
PRIM_MEDIA_HOME_URL,html, // The url if they hit 'home'
PRIM_MEDIA_HEIGHT_PIXELS,512, // Height/width of media texture will be
PRIM_MEDIA_WIDTH_PIXELS,512]); // rounded up to nearest power of 2.
}

string replace_all(string src, string target, string replace)
{
return llDumpList2String(llParseString2List(src,[target],[]),replace);
}

string get_query(key id, string name)
{
string query = llGetHTTPHeader(id,"x-query-string");
query = replace_all(query,"+"," ");
query = llUnescapeURL(query);
list q = llParseString2List(query,["=","&",";"],[]);
integer i = llListFindList(q,[name]);
if (i != -1)
{
return llList2String(q,i+1);
}

return "";
}

default
{
state_entry()
{
llRequestURL();
}

http_request(key id, string method, string body)
{
if (method == URL_REQUEST_GRANTED)
{
url = body + "/";

show(replace_all(html_base,"%url%",url));
}
else if (method == "GET")
{
llSetText(get_query(id,"text"),<1,1,0>,1);
show(replace_all(html_base,"%url%",url));
llHTTPResponse(id,200,"Loading....");
}
}
}
</lsl>

=== The Limits ===
* 1024 bytes per url
* llEscapeURLs means non-alphanumeric characters are 3 bytes (ouch)
** I'm actually not clear on if this is really needed. I seem to sometimes get blank pages if I don't but some pages render fine with out it. Maybe there is a subset of symbols that must be escaped and escaping only those would ease some of the space constraints?
* Must force another page view after form submission since HTTP-In can't generate HTML
* No real way of knowing which avatar is interacting with the HTML

=== The Tricks ===
* <base href="<http-in-url>/">
** HTTP-In urls are long, especially if escaped. In a page that includes more than a single link back to the script, or more than a single form, this can save a lot of space.
* Tiny urls
** You can use url shortening services to create short links to long data urls. In theory this should let you get past the 1k limit quite nicely, however there is overhead in setting up the tiny url.
=== The future? ===
I think there is a lot more potential here than what I have outlined .... if you have ideas or work out great new hacks let me know! Also let me know if it is ok to share those hacks with others. :)
* svg?
* javascript?
* ajax?

=== DHTML / Javascript (Tali Rosca) ===
Tali Rosca sent me the code to render the output of HTTP-In directly. I've wrapped her magic into the build_url and build_response functions in the example below. This example renders a page that is around 3.5k bytes - well past the 1k limit of urls.<br>
'''Pros''':
* Navigation is much smoother and feels more natural
* Only limited by script memory
'''Cons''':
* Links are extremely large: 296 bytes for a link to just the base http-in url.

* I'm not quite sure if it is possible to hook up a form using this method. Ideas?
