From 8f02fd926e14dfad7f5eb77a67a6701f449511e0 Mon Sep 17 00:00:00 2001 From: Justin Clark-Casey (justincc) Date: Thu, 6 Sep 2012 22:12:05 +0100 Subject: If reusing dynamic textures, do not reuse small data length textures that fall below current viewer discard level 2 thresholds. Viewer LL 3.3.4 and before sometimes fail to properly redisplay dynamic textures that have a small data length compared to pixel size when pulled from cache. This appears to happen when the data length is smaller than the estimate discard level 2 size the viewer uses when making this GetTexture request. This commit works around this by always regenerating dynamic textures that fall below this threshold rather than reusing them if ReuseDynamicTextures = true This can be controlled by the [Textures] ReuseDynamicLowDataTextures config setting which defaults to false. --- .../DynamicTexture/DynamicTextureModule.cs | 59 ++++++++++++++++++---- .../Scripting/LoadImageURL/LoadImageURLModule.cs | 41 +++++++++------ .../VectorRender/Tests/VectorRenderModuleTests.cs | 42 +++++++++++++++ .../Scripting/VectorRender/VectorRenderModule.cs | 24 ++++----- 4 files changed, 125 insertions(+), 41 deletions(-) (limited to 'OpenSim/Region/CoreModules/Scripting') diff --git a/OpenSim/Region/CoreModules/Scripting/DynamicTexture/DynamicTextureModule.cs b/OpenSim/Region/CoreModules/Scripting/DynamicTexture/DynamicTextureModule.cs index e09f1a9..1f340df 100644 --- a/OpenSim/Region/CoreModules/Scripting/DynamicTexture/DynamicTextureModule.cs +++ b/OpenSim/Region/CoreModules/Scripting/DynamicTexture/DynamicTextureModule.cs @@ -42,7 +42,7 @@ namespace OpenSim.Region.CoreModules.Scripting.DynamicTexture { public class DynamicTextureModule : IRegionModule, IDynamicTextureManager { -// private static readonly ILog m_log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); + private static readonly ILog m_log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); private const int ALL_SIDES = -1; @@ -54,6 +54,17 @@ namespace OpenSim.Region.CoreModules.Scripting.DynamicTexture /// public bool ReuseTextures { get; set; } + /// + /// If false, then textures which have a low data size are not reused when ReuseTextures = true. + /// + /// + /// LL viewers 3.3.4 and before appear to not fully render textures pulled from the viewer cache if those + /// textures have a relatively high pixel surface but a small data size.
