-LMTSMeshFileLoader
-Written by Jonas Petersen (a.k.a. jox)
-
-Version 1.5 - 15 March 2005
-
-Get the latest version here: http://development.mindfloaters.de/
-
-This class allows loading meshes with lightmaps (*.lmts + *.tga files) that were created
-using Pulsar LMTools by Lord Trancos (http://www.geocities.com/dxlab/index_en.html)
-
-Notes:
-- This version does not support user data in the *.lmts files, but still loads those files (by skipping the extra data).
-
-License:
---------
-
-It's free. You are encouraged to give me credit if you use it in your software.
-
-Version History:
-----------------
-
-Version 1.5 - 15 March 2005
-- Did a better cleanup. No memory leaks in case of an loading error.
-- Added "#include <stdio.h>" for sprintf.
-
-Version 1.4 - 12 March 2005
-- Fixed bug in texture and subset loading code that would possibly cause crash.
-- Fixed memory cleanup to avoid leak when loading more then one mesh
-- Used the irrlicht Logger instead of cerr to output warnings and errors.
- For this I had to change the constructor
- from:
- CLMTSMeshFileLoader(io::IFileSystem* fs, video::IVideoDriver* driver)
- to:
- CLMTSMeshFileLoader(IrrlichtDevice* device)
-
-Version 1.3 - 15 February 2005
-- Fixed bug that prevented loading more than one different lmts files.
-- Removed unnecessary "#include <os.h>".
-- Added "std::" in front of "cerr". This was necessary for Visual Studio .NET,
- I hope it's not disturbing other compilers.
-- Added warning message when a texture can not be loaded.
-- Changed the documentation a bit (minor).
-
-Version 1.2
-- To avoid confusion I skipped version 1.2 because the website was offering
-version 1.2 even though it was only version 1.1. Sorry about that.
-
-Version 1.1 - 29 July 2004
-- Added setTexturePath() function
-- Minor improvements
-
-Version 1.0 - 29 July 2004
-- Initial release
