From 8136cf4075216d09738b8707258581e6db755759 Mon Sep 17 00:00:00 2001 From: Homer Horwitz Date: Sat, 4 Apr 2009 15:43:02 +0000 Subject: Thanks jonc, for a patch that adds rendering of classic clouds. First part of Mantis #964, the necessary clouds image will follow separately. --- .../Region/ClientStack/LindenUDP/LLClientView.cs | 39 ++++- .../Region/CoreModules/World/Cloud/CloudModule.cs | 190 +++++++++++++++++++++ .../Region/Examples/SimpleModule/MyNpcCharacter.cs | 2 + .../Region/Framework/Interfaces/ICloudModule.cs | 38 +++++ .../Region/OptionalModules/World/NPC/NPCAvatar.cs | 2 + .../Shared/Api/Implementation/LSL_Api.cs | 13 +- 6 files changed, 279 insertions(+), 5 deletions(-) create mode 100644 OpenSim/Region/CoreModules/World/Cloud/CloudModule.cs create mode 100644 OpenSim/Region/Framework/Interfaces/ICloudModule.cs (limited to 'OpenSim/Region') diff --git a/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs b/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs index 5c86964..9b2f0ef 100644 --- a/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs +++ b/OpenSim/Region/ClientStack/LindenUDP/LLClientView.cs @@ -1360,7 +1360,7 @@ namespace OpenSim.Region.ClientStack.LindenUDP } /// - /// Send the region heightmap to the client + /// Send the wind matrix to the client /// /// 16x16 array of wind speeds public virtual void SendWindData(Vector2[] windSpeeds) @@ -1369,13 +1369,21 @@ namespace OpenSim.Region.ClientStack.LindenUDP } /// - /// Send terrain layer information to the client. + /// Send the cloud matrix to the client + /// + /// 16x16 array of cloud densities + public virtual void SendCloudData(float[] cloudDensity) + { + ThreadPool.QueueUserWorkItem(new WaitCallback(DoSendCloudData), (object)cloudDensity); + } + + /// + /// Send wind layer information to the client. /// /// private void DoSendWindData(object o) { Vector2[] windSpeeds = (Vector2[])o; - TerrainPatch[] patches = new TerrainPatch[2]; patches[0] = new TerrainPatch(); patches[0].Data = new float[16 * 16]; @@ -1393,11 +1401,34 @@ namespace OpenSim.Region.ClientStack.LindenUDP LayerDataPacket layerpack = TerrainCompressor.CreateLayerDataPacket(patches, TerrainPatch.LayerType.Wind); layerpack.Header.Zerocoded = true; - OutPacket(layerpack, ThrottleOutPacketType.Wind); } /// + /// Send cloud layer information to the client. + /// + /// + private void DoSendCloudData(object o) + { + float[] cloudCover = (float[])o; + TerrainPatch[] patches = new TerrainPatch[1]; + patches[0] = new TerrainPatch(); + patches[0].Data = new float[16 * 16]; + + for (int y = 0; y < 16; y++) + { + for (int x = 0; x < 16; x++) + { + patches[0].Data[y * 16 + x] = cloudCover[y * 16 + x]; + } + } + + LayerDataPacket layerpack = TerrainCompressor.CreateLayerDataPacket(patches, TerrainPatch.LayerType.Cloud); + layerpack.Header.Zerocoded = true; + OutPacket(layerpack, ThrottleOutPacketType.Cloud); + } + + /// /// Tell the client that the given neighbour region is ready to receive a child agent. /// public virtual void InformClientOfNeighbour(ulong neighbourHandle, IPEndPoint neighbourEndPoint) diff --git a/OpenSim/Region/CoreModules/World/Cloud/CloudModule.cs b/OpenSim/Region/CoreModules/World/Cloud/CloudModule.cs new file mode 100644 index 0000000..e164f08 --- /dev/null +++ b/OpenSim/Region/CoreModules/World/Cloud/CloudModule.cs @@ -0,0 +1,190 @@ +/* + * 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.
