* Tweak the LLSetStatus results in the ODEPlugin. Hopefully it's a little less unstable.
* ODEPlugin is using experimental math for LLSetStatus, use with caution! :)
* WebStatsModule doesn't crash on restart. GodsModule doesn't crash when there is no Dialog Module. LLUDPServer doesn't crash when the Operation was Aborted.
* ODEPlugin does 'Almost NaN' sanity checks.
* ODEPlugin sacrifices NaN avatars to the NaN black hole to appease it and keep it from sucking the rest of the world in.
* Now validating input to the Physics scene and warning when something is awry.
* This should help nail down that Non Finite Avatar Position Detected issue.
* This may help one of the symptoms or mantis 3363 , however it probably won't solve the occasional NonFinite Avatar Position detected.. issues that some people see. That is probably an entirely different issue(NaN).
* In most cases, the setting in OpenSim.ini.example is taken as the canonical one since this is the file virtually everyone ends up using
* OpenSim will start up with a blank OpenSim.ini, in which case sqlite is the default database (as before)
* Add some comments to the Wind Module
* Add the BinBVH decoder/encoder as a scene object (to encode/decode animations programmatically).
* Add m_sitState for upcoming code to improve sit results.
* I'm concerned however that the 'minimum fly height' should really be implemented in ScenePresence and not in the specific physics plugin so that all of the physics plugins can take advantage of it and if desired, a person could swap out the 'minimum fly height' functionality with other functionality.
llSetHoverHeight() should not clamp the x/y position of an object the way MoveTo does,
and it should recalculate the absolute height to hover at as an object moves to reflect
the current ground/water height under it.
Correctly implementing required adjusting the Physics interfaces and implementing at
the physics plug-in level. The attached is a patch that correctly implements
llSetHoverHeight() including updates to the ODE physics plug-in.
* Added log4net dependency to physxplugin in prebuild.xml.
* Added missing m_log fields to classes.
* Replaced Console.WriteLine with appropriate m_log.Xxxx
* Tested that nant test target runs succesfully.
* Tested that local opensim sandbox starts up without errors.
* This fixes crashing on large sets of physical prims because of stack collisions (assuming you follow the directions on linux for starting ode with ulimit). After the maximum joints are created, objects will start to fall through the ground and be disabled. Not the best solution, but it's better then a crash caused by a stack collision with the process exceeding the maximum available memory/recursions per thread.
* Make a clean region, make a stack of 5000 prim, 20 layers high. Make them physical, *SLOW*, but no crash.
* The actual AABB of the heightfield on the Z is now determined by the minimum and maximum heightfield value in the terrain array (assuming it's a reasonable number). This might optimize collisions in simulators that have a small difference between minimum and maximum heightfield values.
* If you log-in while the simulator is starting up, you won't be able to move and the sim stats will say 0 FPS, and 0 Physics Frames and you may see only terrain. Once the sim finishes starting up, it'll all resume as normal.
- Adapted code to match the corrected signatures
- Fixes Mantis #2934. Hopefully.
Note: Physics on linked objects still don't work correctly:
It doesn't crash the region anymore, but the example object in
the mentioned mantis now falls through the ground.
On a call of llVolumeDetect(1) (or any other number !=0) volume
detection is enabled. Together with VD, the phantom flag is set to the GUI.
On a call of llVolumeDetect(0), vd detection is switched of again,
also the phantom state is removed. On a call to llSetState(STATE_PHANTOM,
false) while VD is active, also VD is switched off. The same is true for
unchecking the phantom flag via GUI. This allows to take back VD without
the need to script just by removing the phantom flag.
Things missing in this patch: persistance of the volume-detection flag.
This needs more discussion and will be included in another patch soon.
* This pushes an identifier for the OpenSim scene to the physics scene. This allows log messages from the physics scene to identify which OpenSim scene they relate to.
* Thanks Gerhard
* Warning! Physics API change. This means that the NBodySimulation needs to be updated!
* PhysicsActor -> void SetVolumeDetect(int) needs to go into classes that use PhysicsActor as their base class.
* Fixed a bug that caused physics proxies to be scattered when you link an object.
* Single physical prim work exactly the same as before, just linked physical prim will have changed.
* Initializes ODE only when a scene is grabbed rather than on plugin load. This means we don't initialize ode if that physics engine is not used, and it allows other ode use
plugins to be used instead.
* Implement the linear impulse portion of llPushObject. We should have a lsl compatible implementation of that portion of the push. Angular.. well. still have yet to implement a torque accumulator.
* llPushObject respects the region and parcel settings for Restrict Push, it also respects GodMode as is defined in the LSL spec.
* Additionally, you can probably get more physical prim now together.. though, I think this puts us back on par with where we were in the beginning of the year on number of physical objects. Experiment. Make videos. Send Feedback. Enjoy.
* If you are hosting many regions on a single instance, you will probably notice a decrease in region startup time and maybe a slight increase in performance.
* Single regions won't notice anything different
* Re-enabled the native ODE prim types when possible
* Fixed several invalid assumptions in the prim recycle process.
* Added better message for 'reused a disposed physicsactor'
* Added a way to recover from errors during collision_optimized
* Added a way to recover from an error condition where prim_geom wasn't reset properly
* If you're experiencing knee bendiness try the windows settings, as the *nix settings seem to now be incorrect. (this update does that, but you may have your own opensim.ini settings active.
* Mac users, pray to chi11ken to make you a .dylib version
* This is semi-tuned and post teravus hack. (Though I didn't apply the terrain pitting fix hack. I'm still deciding if it's necessary as there was a lot of work over the past several months on the heightfield collider.
* Please use '--enable-shared --disable-demos --disable-asserts' if you are building your own libode in the configure step. Asserts are pretty much useless for use with .NET
* This also updates ODE.NET as, there were some API changes in May that were just added to ODE.NET today.
* This is a HUGE OMG update and will definitely have unknown side effects.. so this is really only for the strong hearted at this point. Regular people should let the dust settle.
* This has been tested to work with most basic functions. However.. make sure you back up 'everything' before using this. It's that big!
* Essentially we're back at square 1 in the testing phase.. so lets identify things that broke.
Small prims now get a full mesh if they are physical
Fixed a logic bug that was preventing many prim meshes from having excess memory cleaned up
Switched to more conservative method of vertex and triangle list trimming to prevent possible crash
* Some situations do not match the client's render of the tori, we know and are working on it. This is an initial support patch, so expect it to not be exact.
* Some tapers are acting slightly odd. Will fix.
* This includes if you want to mesh sculpties and the Level of detail on the sculptie meshing for non physical and a separate LOD on physical sculpties.
* The options range from gravity.. to avatar movement speed, to friction management.. to object density.. to update throttling.
* The main purpose of this is to provide configuration options for ODE and other physics plug-ins that are advanced enough to be able to be configured.
* Detaching from right clicking in world, detaches to your inventory.
* If you go up to a prim and attach it from in world, it appears in your inventory.
* Attachment placement is saved when you detach them.
* Choosing wear remembers your last attachment point from inventory.
* Wrote a method to update an inventory item's asset and sends the updated inventory item to the Client
* Wrote a recursive method to find the folder of a known existing inventory item.
* Removed a block on physics object position on creation. This might crash a region or two, let us know via Mantis if your region crashes because of a physics out of bounds error.
* Drop doesn't work. The menu item doesn't even come up. Don't know why :P.
* Your friends can see your attachments now. People who appear in the sim after you've attached something can also see your attachments.
* You can position & rotate your attachments now. Positions do *not* save.
* You can detach attachments now the regular way.
* Attachments do not cross into other regions with you..(this isn't too far off)
* Updated ODE to not request terse updates on child prim.
* Currently if you apply that to only one or two axis you get unpredictable and sometimes explosive results.
* Three axis works well enough to play with it anyway. More work is needed here.
* Fixed an incorrectly named method in ODE.NET
* It doesn't generate at_target events, because they don't exist yet in the script engine.
* The Tau is different, however, compatible with scripts I tested.
* Not perfect... but pretty good.
* Added osSetPrimFloatOnWater(BOOL) to make Physical prim float at the water level.
* osSetPrimFloatOnWater(TRUE); or osSetPrimFloatOnWater(FALSE);
* By default, prim do not float at the water level.
* More work is needed on the floating, but it's a start.
* ODE: Added support for larger box stacks. (they're slow, but they work)
* ODEPlugin no longer tries to 'catch up' with the simulator frame rate if it gets behind. Catching up was causing a lot of problems with larger box stacks and other things that stall the simulator (like saving prim in the datastore)
* To play with this you must link your prim before setting it physical, otherwise they won't link in the physics engine properly. This will also be fixed.
* Currently the linked prim are extremely unstable because I have yet to implement combining of forces with the same normal. This will also be fixed. In fact, the whole PhysicsActor, ODEPrim relationship will be reworked to consider groups from the get-go.
* This implementation is better then it crashing your sim, so I'm commiting it for now.
** Added more realistic calculations of mass for the rest of the supported prim shapes+holes+cuts+tapers. Previously they were the generic height * width * length. Spheres roll (Angular velocity) more realistically, etc.
* When you select a physical prim, it stops while you've got it selected.
* When you move or alter a prim in some manner, it doesn't become collidable until you de-select it
* When you select a prim, it doesn't become temporarily 'phantom' until you make some change to it while it's selected. (this prevents accidental selections in prim floor from causing it to go phantom on you(but don't move it or you'll fall))
* There's one major difference, and that's a physical object won't stop if you don't have permission to edit it. This prevents people who don't have edit permissions on a prim from stopping it while it's moving.
* Converted all instances of "256" spotted to use RegionSize instead. Some approximations used for border crossings (ie 255.9f) are still using that value, but should be updated to use something based on RegionSize.
* Moving Terrain to a RegionModule, implemented ITerrainChannel and TerrainModule - nonfunctional, but will be soon.
* Updated the ode.dll for windows with a more reasonable stack space reserve. Linux users will need to type ulimit -s 262144 before starting up OpenSimulator if using Physical Prim to protect against stack collisions. or run the included ./bin/opensim-ode.sh to start up OpenSimulator in ODE mode.
* Added internal collision score and am keeping track of 'high usage' prim.
* Tweaked collisions some more
* Tested up to 460 physical prim in extremely close quarters (which was previously impossible in OpenSim). After 460 in tight quarters, physics slows down enough to make it hard to do any moving, however.. non physics things still work, such as logging on to the simulator, etc.
** Sending the actual TimeDilation to the client now instead of the 62455 constant. The client is *supposed* to use that value to sync with the simulator. (actually sending ushort.maxvalue * TimeDilation)
** Disabling prim that inter-penetrate instead of just not attaching a joint
** Reduced prim spin a 'little' bit, but not *enough*
** Tweaked the TimeDilation algorithm to be closer to 1.0 by default and various changes to the sim stats reporter
** Created a .SetValues method to PhysicsVector so we can simply call the setvalues function instead of .x, .y, .z sets.
** Experimented with a .GetBytes Method on PhysicsActor to be able to use the LLVector3.FromBytes() method.
** Upped the Inter-penetration depth to 0.25 instead of .08.
* Just to give you an idea of the difference .. previous ODE_STEPSIZE was 0.005f - 1000/5 = 200fps - 10 substeps with fallback to 5 substeps when things get slow
* *nix avatar may fall over again, *sorry*
* Set the avatar's radius to 0.37m, I think this gives the *best* balance between spaces the avatar can fit, and the ability to climb steps
* Fixed a few things
* Tweaked some more
* Played with gravity (-9.8m/s)
* Cleaned up copyright notices in AssemblyInfo.cs's
* Added Copyright headers to a bunch of files missing them
* Replaced several common string instances with a static constant to prevent reallocation of the same strings thousands of times. "" -> String.Empty is the first such candidate.
* There will be bugs, you can count on that. To avoid them, set the linksets phantom
* After region restart, the linksets restore in a non collidable state.
* Linksets can but shouldn't be made physical with the physical checkbox or when you unlink them, they tend to explode.
* After creating a linkset, you have to move the linkset or set it phantom and not phantom for it to become collidable.
* There's a few ParentGroup references that need to be refactored.
* Did some goofy math undoing in the Sim Stats Reporter
* More reduction to the amount of calls per second to UnManaged ODE code
* Added a significant amount of comments to ODE
** - avatar can navigate stairs better now
** - avatar can land without shooting into the air
** - excessive collisions with the ground are tempered somewhat and should only shoot the avatar up 20m instead of 200m
** - Try Catched a TextureDownloadModule.cs array out of bounds error with a report that causes it not to crash the sim, however it reports a few important items for tracking it down.
* Fixes:
* -- duplicating Active physical object causes objects to explode in opposite directions
* -- Rezzing objects too close to you avatar causes avatar to shoot around in odd directions
* Vanity
* Exposed the mass as a PhysicsActor read only property (so scripts can get at it - hint hint -)
* Hollow and Path Cuts affect the prim mass (all Hollow Types are supported in this calculation (sphere,square,triangle))
* Prim no longer sink into the ground.
* added Util.Clip(value, min, max)
* modified asset cache's numPackets calculation to use max packet size (600) instead of 1000
* removed a few magic numbers
* Added the child_get_tasks OpenSim.ini flag for testing the UDP packet sending code and packet throttler. This flag gets purposely disabled in grid mode. This flag also has the consequence that you can see the prim in neighboring regions without going into them. Be warned, this causes tons of dropped packets.
* Reduced ground friction when an avatar is moving
* Followed Dan's advice and moved the walk/run movement controller to target_velocity instead of on the total movement
* Reduced PID_D power by 1/5th (80)
* More avatar movement tweaks.
* Added glue to send it to the Physics Engines (in meters)
* ODE Initial implementation of Avatar Height :D Change your height and not get all knee bendy
* ODE - Fixed the iscolliding property to report a static true when colliding.
* Added reporting of collisions to call UpdateMovementAnimations
* Added Jump - air animation (with arms outstretched).
* Added Fall Animations
* ODE - Added a small amount of X, Y motion control while jumping or Falling
* ODE - Avatar movement animations are still a bit odd sometimes, and had to get this up there.
* Added a ThrottleUpdates member to PhysicsActor to expose 'throttle' ability to the Scene.
* Updated the ode.dll file with a fix to invalid data passed to ODE's heightfield collision calculator.
* Removed the 'constant poll method' from SceneObjectPart.cs - It was bad :P
* Updated some Masses in ODE to help large prim slow down by friction easier.
Note this has lead to a big flat project, but I think a lot of the files we most likely don't even use any longer. And others belong in other projects/namespaces anyway.
seriously, this is quite the update. Fixes a number of nagging physics problems, including avatar shell size/shape
The internal logic is quite different, and CPU usage may be affected.
Also some work remains wrt flying. Please test this rev out before you deploy widely
Implemented that method in ODE plugin.
Hooked it up so when deleting/taking prims into your inventory they will be removed from physics engine.
Enabled the other physics hook ups in Scene.cs (and also added registering prims with physics plugin when they are rezzed from Inventory.)
So now to get the avatar to prim collision testing working, just change to use the ODE plugin (in the OpenSim.ini file, physics = OpenDynamicsEngine). Remember though ODE only really works (without problems) when running with a single region.
attached the links to that from SceneObject, so now resizing works (as much as resizing currently works in opensim, fixing resizing in general is on my todo list for today).
Rotation of a root prim also now updates the physics engine.
So think there really is only deleteprim left, then it should be usable (Different shapes (other than boxes that it currently uses) can wait a little bit longer).
[of course there are still the other issues of ODE not really working when there is more than one region in a instance of opensim].
