Private Estate Management Companies

2011-09-18T20:54:30Z

Sally LaSalle:

There are many companies, large and small, that rent/sell private estate land in Second Life. They range from individual residents who rent single parcels to major holding companies with dozens of privately owned sims.
There are pros and cons between renting land from Linden Labs and private owners, and then even between renting from single parcel owners and large companies.

Below is a list of some of the many privately owned companies that offer Private Estate sales and rentals.
It should be noted that none of these companies represent Linden Labs directly or are officially endorsed by them in any way.
It is in fact recommended that one should always review and research any company before engaging in any financial transaction; hence, these companies are listed here for the convenience of visitors to this page to begin their own research.

== About Me ==

I have benefited greatly from the contributors to this forum and to the code in the forum script library. So, here is a contribution, which hopefully will be useful for someone.

== Scripts ==

[[Color conversion scripts]] convert from RGBtoHSV and HSVtoRGB. Use these freely to convert between Red Green Blue (RGB) into Hue Saturation Value (HSV).

Sally LaSalle: added color RGB to HSV script link

{{LSL Header}}
==Script Library==

<div id="box">
<div style="padding: 0.5em 0.5em 1.5em">
There are many [[script|scripts]] that have become buried in the [http://forums.secondlife.com/forumdisplay.php?f=15 Scripting Library forum], were lost with the death of the scripting forums, or sit idle in [[inventory|inventories]] that could be useful and should be more accessible.

Other scripters may be in the same situation. This wiki is a well-suited medium for a script library. Feel free to add your scripts to the script library by creating new pages for them and linking to those pages here.

Note that there are many more scripts in the LSL Library here, but you can't get to them if you don't know they exist, because they are subpages now, instead of an automatically updated category. Good luck searching.

== Rules for posting: ==
<div style="padding: 0.5em">
#Your script must be tested and working. If it's not, stick it in your user-space until it is. This is a list of working, usable scripts.
#Add a link to your script's page here. Link back to this page from your script's page. Start your page with <nowiki>{{LSL Header}}</nowiki>.
#Do not add scripts that duplicate the same functionality as an existing script or built in {{LSLGC|Functions|function}}. If yours does, explain why.

{{LSL Header
}}{{#vardefine:header_title|Color conversion scripts

The following functions convert between LSL [[color]] in Red Green Blue (RGB) format and color in Hue Saturation Value (HSV) format.
The functions are based on "c" algorithms from [http://www.cs.rit.edu/~ncs/color/t_convert.html c color conversion] but required some debugging and extensive re-working to fit them in to LSL. For a discussion of HSV color format please see the wikipedia entry at [http://en.wikipedia.org/wiki/HSV_color_space HSV Color]

RGB to HSV follows:

// by Sally LaSalle, code released to the public domain under GNU license.

// takes an RGB color as a vector, with range <float R[0,1], float G[0,1], float B[0,1]>
// returns a vector with HSV ranged from <float H[0,360], float S[0,1], float V[0,1]>
