From 52c55c8c23a492d4cf7df9c9d496fae1868c6914 Mon Sep 17 00:00:00 2001 From: Teravus Ovares Date: Sun, 1 Jun 2008 04:33:07 +0000 Subject: * Applying Dahlia's patch : 0001429: Patch to fix prism physical mesh and add path start and end to skew z offset of circular path prim meshes (PATCH attached) * Apparently this fixed a bug in my code that caused PushX to appear to work and pushX didn't appear to work after the patch.. so I fixed that after applying this patch and PushX actually works now. --- OpenSim/Region/Physics/Meshing/Extruder.cs | 42 ++++---- OpenSim/Region/Physics/Meshing/Meshmerizer.cs | 150 +++++++++++++++++++------- 2 files changed, 132 insertions(+), 60 deletions(-) (limited to 'OpenSim') diff --git a/OpenSim/Region/Physics/Meshing/Extruder.cs b/OpenSim/Region/Physics/Meshing/Extruder.cs index 8a95df9..54ef4ce 100644 --- a/OpenSim/Region/Physics/Meshing/Extruder.cs +++ b/OpenSim/Region/Physics/Meshing/Extruder.cs @@ -24,6 +24,7 @@ * (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OF THIS * SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. */ +//#define SPAM using OpenSim.Region.Physics.Manager;
