0.5.0 is NOW!

Posted 29 days ago by Baba

The libsecondlife team is proud to announce the release of the final version of libsecondlife.

This is a maintenance release that contains over 60 new features and bug fixes since our previous release in April! This will be our last release ... [More] under the name libsecondlife. Due to trademark/licensing issues with the use of the name 'secondlife' we have renamed the library to libopenmv.

Some of the highlights included in this release:

Texture Cache improves the speed of baking significantly
Improved Baking support
Improvements in Types
Improved API Documentation

A full list of new features added and bugs fixed is available in the jira changelog

You can download this release from our Downloads page. Full API Documentation for this release can be found on the Documentation page.

Our upcoming 0.6 release will provide better library organization, more re-usable components and more documentation than ever before.

To submit trouble reports please use the "Create New Issue" link in our jira issue tracker at http://jira.openmv.org.

Thanks to all the Testers, bug reporters, patch submitters and developers who contributed to this release!

Regards,

The libsecondlife team (henceforth to be known as The libopenmv Ninjas) [Less]

New servers usher in a new high-technology era

Posted 4 months ago by Baba

OpenMetaverse is gettting some new servers to handle all the cool stuff we want to do. Recently we've run into some performance problems with the current server and that required us to turn off ViewVC until we move to some better ... [More] hardware.

After the move we'll be setting up some new services including a Jira issue tracker and TeamCity continuous integration(automated builds and testing).

This should happen within the next two to three weeks. [Less]

Reverse-engineering the CRC function for UpdateInventoryItem

Posted 5 months ago by Baba

This article was written in September of 2006 by libsecondlife developer bushing. It has been salvaged from an old database and presented here for your reading pleasure

I've always been a big fan of IDA Pro, and have often ... [More] just
disassembled random binaries with the thing to see what it could
come up with. When I saw the bounty posted, I sprung at the
chance to actually do something useful with it.

As you may have guessed, I do my primary development on a
PowerPC Mac, which means I end up running IDA under VirtualPC
(which sucks) or on a x86 Linux box running VMWare (which sucks
a little less). I ended up having to borrow a Windows-running
laptop to do this, though.

Part 1: CRC table
IDA 5.0 took a while to load up "Second Life.exe" (v1.10.5.1),
but it lets you start playing while it continues to process in
the background. I gave it a 20-minute head start before I
started to poke around.

One nice thing about trying to take apart CRC or hash functions
(MD5, SHA, etc), is that they all use tables (of various sizes)
which you are guaranteed to find in a binary that uses that
function (assuming there's no packing or encryption -- which is
the case here). CRC32's table is contained in libsecondlife in
SecondLife.cs:

private readonly static uint[] crcLookup = new uint[] {
0x00000000, 0x77073096, 0xEE0E612C, 0x990951BA,
0x076DC419, 0x706AF48F, 0xE963A535, 0x9E6495A3, [Less]
