From 2ef4ccf89edc591319d0b43915b02d7bc8b8e3c9 Mon Sep 17 00:00:00 2001 From: Teravus Ovares Date: Mon, 18 Aug 2008 08:25:58 +0000 Subject: * Slightly better implementation of prim volume drawing on the maptile using projection of an oriented bounding box. This isn't quite right yet. Experimental. It takes about 3 times longer then the previous version, however produces better results. --- .../Modules/World/WorldMap/MapImageModule.cs | 187 +++++++++++++++++++-- 1 file changed, 177 insertions(+), 10 deletions(-) (limited to 'OpenSim/Region/Environment') diff --git a/OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs b/OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs index 52ee84d..6d51c88 100644 --- a/OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs +++ b/OpenSim/Region/Environment/Modules/World/WorldMap/MapImageModule.cs @@ -42,10 +42,24 @@ using libsecondlife;
