From df7fb207a87b1b07a00600d5b66e717ac2332b4f Mon Sep 17 00:00:00 2001 From: Mic Bowman Date: Sat, 8 Jan 2011 13:33:07 -0800 Subject: Moved the map tile processing used by the Simian Grid Frontend into a separate region module. Configuration settings added to the defaults ini file. Others may find this useful for pushing map tiles to a separate server. --- .../SimianGrid/SimianGridMaptileModule.cs | 261 +++++++++++++++++++++ .../SimianGrid/SimianGridServiceConnector.cs | 86 ------- 2 files changed, 261 insertions(+), 86 deletions(-) create mode 100644 OpenSim/Services/Connectors/SimianGrid/SimianGridMaptileModule.cs (limited to 'OpenSim/Services/Connectors') diff --git a/OpenSim/Services/Connectors/SimianGrid/SimianGridMaptileModule.cs b/OpenSim/Services/Connectors/SimianGrid/SimianGridMaptileModule.cs new file mode 100644 index 0000000..dd8fe2b --- /dev/null +++ b/OpenSim/Services/Connectors/SimianGrid/SimianGridMaptileModule.cs @@ -0,0 +1,261 @@ +/* + * 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 OpenSimulator 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.
