From f5c312bc3c2567449c7268a54a08a54119f58d53 Mon Sep 17 00:00:00 2001 From: Adam Frisby Date: Wed, 30 Apr 2008 21:16:36 +0000 Subject: * Refactored Environment/Modules directory - modules now reside in their own directory with any associated module-specific classes. * Each module directory is currently inside one of the following category folders: Agent (Anything relating to do with Client<->Server communications.), Avatar (Anything to do with the avatar or presence inworld), Framework (Classes modules can use), Grid (Grid traffic, new OGS2 grid comms), Scripting (Scripting functions, etc), World (The enrivonment/scene, IE Sun/Tree modules.) * This should be moved into a seperate project file. --- .../Scripting/VectorRender/VectorRenderModule.cs | 361 +++++++++++++++++++++ 1 file changed, 361 insertions(+) create mode 100644 OpenSim/Region/Environment/Modules/Scripting/VectorRender/VectorRenderModule.cs (limited to 'OpenSim/Region/Environment/Modules/Scripting/VectorRender/VectorRenderModule.cs') diff --git a/OpenSim/Region/Environment/Modules/Scripting/VectorRender/VectorRenderModule.cs b/OpenSim/Region/Environment/Modules/Scripting/VectorRender/VectorRenderModule.cs new file mode 100644 index 0000000..4fba5b9 --- /dev/null +++ b/OpenSim/Region/Environment/Modules/Scripting/VectorRender/VectorRenderModule.cs @@ -0,0 +1,361 @@ +/* + * Copyright (c) Contributors, http://opensimulator.org/ + * See CONTRIBUTORS.TXT for a full list of copyright holders. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * * Redistributions of source code must retain the above copyright + * notice, this list of conditions and the following disclaimer. + * * Redistributions in binary form must reproduce the above copyright + * notice, this list of conditions and the following disclaimer in the + * documentation and/or other materials provided with the distribution. + * * Neither the name of the OpenSim Project nor the + * names of its contributors may be used to endorse or promote products + * derived from this software without specific prior written permission. + * + * THIS SOFTWARE IS PROVIDED BY THE DEVELOPERS ``AS IS'' AND ANY + * EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED + * WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE + * DISCLAIMED.
