From 759636f37e4ea212af4ca40565b2d4e9be1eebbe Mon Sep 17 00:00:00 2001 From: Dr Scofield Date: Tue, 9 Jun 2009 06:39:27 +0000 Subject: From: Alan Webb This change addresses two issues: [1] It adds a flag field to the blendface call which allows the caller to indicate whether or not the generated asset is temporary, and whether or not the asset being replaced should be explicitly retired fromt the memory cache. The decimal values correspond to: 0 - Permanent asset, do not expire old asset 1 - Permanent asset, expire old asset 2 - Temporary asset, do not expire old asset 3 - Temporary asset, expire old asset '3' corresponds to the default behavior seen today, and is the continued behavior of the non-blendface calls. [2] The dynamic texture routines are highly-asynchronous and can be scheduled simultaneously on a multi-core machine. The nature of the texture management interfaece is such that updates may be lost, and the nature of asynchornous operation means that they may be processed out of order. A lock has been added to ensure that updates are at least atomic. No attempt has been made to enforce ordering. The lock applies to the SceneObjectPart being updated and is held for the lifetime of the TextureEntry used to carry texture updates (the one instance carries all faces supported by the prim). Users of these services should remember that the dynamic texture call is asynchronous and control will be returned *before* the texture update has actually occurred. As a result, a isubsequent GetTexture call may not return the expected asset id. A script must wait for the corresponding TEXTURE_CHANGED event before retrieving any texture information. --- OpenSim/Region/ScriptEngine/Shared/Api/Interface/IOSSL_Api.cs | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'OpenSim/Region/ScriptEngine/Shared/Api/Interface') diff --git a/OpenSim/Region/ScriptEngine/Shared/Api/Interface/IOSSL_Api.cs b/OpenSim/Region/ScriptEngine/Shared/Api/Interface/IOSSL_Api.cs index e337c6b..debbad6 100644 --- a/OpenSim/Region/ScriptEngine/Shared/Api/Interface/IOSSL_Api.cs +++ b/OpenSim/Region/ScriptEngine/Shared/Api/Interface/IOSSL_Api.cs @@ -59,12 +59,12 @@ namespace OpenSim.Region.ScriptEngine.Shared.Api.Interfaces string osSetDynamicTextureURLBlend(string dynamicID, string contentType, string url, string extraParams, int timer, int alpha); string osSetDynamicTextureURLBlendFace(string dynamicID, string contentType, string url, string extraParams, - bool blend, int timer, int alpha, int face); + bool blend, int disp, int timer, int alpha, int face); string osSetDynamicTextureData(string dynamicID, string contentType, string data, string extraParams, int timer); string osSetDynamicTextureDataBlend(string dynamicID, string contentType, string data, string extraParams, int timer, int alpha); string osSetDynamicTextureDataBlendFace(string dynamicID, string contentType, string data, string extraParams, - bool blend, int timer, int alpha, int face); + bool blend, int disp, int timer, int alpha, int face); LSL_Float osTerrainGetHeight(int x, int y); LSL_Integer osTerrainSetHeight(int x, int y, double val); -- cgit v1.1
