From 646bbbc84b8010e0dacbeed5342cdb045f46cc49 Mon Sep 17 00:00:00 2001 From: MW Date: Wed, 27 Jun 2007 15:28:52 +0000 Subject: Some work on restructuring the namespaces / project names. Note this doesn't compile yet as not all the code has been changed to use the new namespaces. Am committing it now for feedback on the namespaces. --- .../OpenSim.Region.Terrain.BasicTerrain.csproj | 110 +++ ...OpenSim.Region.Terrain.BasicTerrain.csproj.user | 12 + .../Properties/AssemblyInfo.cs | 62 ++ .../Region/Terrain.BasicTerrain/TerrainEngine.cs | 786 +++++++++++++++++++++ .../Region/Terrain.BasicTerrain/TerrainFilter.cs | 103 +++ 5 files changed, 1073 insertions(+) create mode 100644 OpenSim/Region/Terrain.BasicTerrain/OpenSim.Region.Terrain.BasicTerrain.csproj create mode 100644 OpenSim/Region/Terrain.BasicTerrain/OpenSim.Region.Terrain.BasicTerrain.csproj.user create mode 100644 OpenSim/Region/Terrain.BasicTerrain/Properties/AssemblyInfo.cs create mode 100644 OpenSim/Region/Terrain.BasicTerrain/TerrainEngine.cs create mode 100644 OpenSim/Region/Terrain.BasicTerrain/TerrainFilter.cs (limited to 'OpenSim/Region/Terrain.BasicTerrain') diff --git a/OpenSim/Region/Terrain.BasicTerrain/OpenSim.Region.Terrain.BasicTerrain.csproj b/OpenSim/Region/Terrain.BasicTerrain/OpenSim.Region.Terrain.BasicTerrain.csproj new file mode 100644 index 0000000..24667e5 --- /dev/null +++ b/OpenSim/Region/Terrain.BasicTerrain/OpenSim.Region.Terrain.BasicTerrain.csproj @@ -0,0 +1,110 @@ + + + Local + 8.0.50727 + 2.0 + {C9E0F891-0000-0000-0000-000000000000} + Debug + AnyCPU + + + + OpenSim.Region.Terrain.BasicTerrain + JScript + Grid + IE50 + false + Library + + OpenSim.Region.Terrain.BasicTerrain + + + + + + False + 285212672 + False + + + TRACE;DEBUG + + True + 4096 + False + ..\..\..\bin\ + False + False + False + 4 + + + + False + 285212672 + False + + + TRACE + + False + 4096 + True + ..\..\..\bin\ + False + False + False + 4 + + + + + ..\..\..\bin\libTerrain-BSD.dll + False + + + Microsoft.JScript.dll + False + + + ..\..\..\bin\openjpegnet.dll + False + + + System.dll + False + + + System.Data.dll + False + + + System.Drawing.dll + False + + + System.Xml.dll + False + + + + + + + Code + + + Code + + + Code + + + + + + + + + + diff --git a/OpenSim/Region/Terrain.BasicTerrain/OpenSim.Region.Terrain.BasicTerrain.csproj.user b/OpenSim/Region/Terrain.BasicTerrain/OpenSim.Region.Terrain.BasicTerrain.csproj.user new file mode 100644 index 0000000..6841907 --- /dev/null +++ b/OpenSim/Region/Terrain.BasicTerrain/OpenSim.Region.Terrain.BasicTerrain.csproj.user @@ -0,0 +1,12 @@ + + + Debug + AnyCPU + C:\New Folder\second-life-viewer\opensim-dailys2\opensim15-06\NameSpaceChanges\bin\ + 8.0.50727 + ProjectFiles + 0 + + + + diff --git a/OpenSim/Region/Terrain.BasicTerrain/Properties/AssemblyInfo.cs b/OpenSim/Region/Terrain.BasicTerrain/Properties/AssemblyInfo.cs new file mode 100644 index 0000000..827c68f --- /dev/null +++ b/OpenSim/Region/Terrain.BasicTerrain/Properties/AssemblyInfo.cs @@ -0,0 +1,62 @@ +/* +* Copyright (c) Contributors, http://www.openmetaverse.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.
