Code Snippet: Converting OpenMetaverse.Primitive to OpenSimulator.SceneObjectPart at Adam Frisby

without comments

Pardon this being a code-only post, but I figured it might be useful to anyone doing work with both OpenMetaverse and OpenSim – currently we store primitive data in a fairly different manner internally, this code converts between the two, and allows you to take a OpenMV.Primitive and get a OpenSim SOP out of it.

private SceneObjectPart FromPrim(Primitive orig)
        {
            bool root = orig.ParentID == 0;

SceneObjectPart sop = new SceneObjectPart();
            sop.LastOwnerID = orig.OwnerID;
            sop.OwnerID = orig.OwnerID;
            sop.GroupID = orig.GroupID;

sop.CreatorID = orig.Properties.CreatorID;

sop.OwnershipCost = orig.Properties.OwnershipCost;
            sop.ObjectSaleType = (byte)orig.Properties.SaleType;
            sop.SalePrice = orig.Properties.SalePrice;
            sop.CreationDate = (int)Utils.DateTimeToUnixTime(orig.Properties.CreationDate);

// Special
            sop.ParentID = 0;

sop.OwnerMask = (uint)orig.Properties.Permissions.OwnerMask;
            sop.NextOwnerMask = (uint)orig.Properties.Permissions.NextOwnerMask;
            sop.GroupMask = (uint)orig.Properties.Permissions.GroupMask;
            sop.EveryoneMask = (uint)orig.Properties.Permissions.EveryoneMask;
            sop.BaseMask = (uint)orig.Properties.Permissions.BaseMask;

sop.ParticleSystem = orig.ParticleSys.GetBytes();

// OS only
            sop.TimeStampFull = 0;
            sop.TimeStampLastActivity = 0;
            sop.TimeStampTerse = 0;

// Not sure nessecary
            sop.UpdateFlag = 2;

sop.InventorySerial = 0;
            sop.UUID = orig.ID;
            sop.LocalId = orig.LocalID;

            sop.Material = 0;
            sop.RegionHandle = orig.RegionHandle;

sop.GroupPosition = orig.Position;

if (!root)
                sop.OffsetPosition = orig.Position;
            else
                sop.OffsetPosition = Vector3.Zero;

            sop.Color = Color.White;
            sop.Text = orig.Text;
