* 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.

units may not match the Linden implementation.

of some of the parameters we pass to it's constructor now like, 'm_allowPhysicalPrim', 'seeIntoOtherRegions', etc.. so on
* 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.

not the attachment.

|
* Nothing user facing yet.
|
|
* 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.
|
|
* Added WaterLevel support to the ODEPlugin. More on this later.

joints. This will change quite drastically, however it's fun to play with.
* 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.

* 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.

got a solution for you! For a limited time, you can be the right height after border crossings automatically. Just three easy payments of $9.95 and make sure your neighbor is sending child agent updates!
|

turned out to be that the Static PhysicsVector.Zero was transferring velocities between all non fixed objects. Not so static after all :(. Finding it was cruel and unusual punishment from the CLR.
* Therefore, when you run through a pile of prim you won't see things rotate when they're not supposed to anymore.
* Avatars don't float off either.
|
|
* 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.

(though I still don't recommend it for welcome regions unless object build is off.
* 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.

* In ODE, disposing of all of the ODE objects and the ODE World to reclaim memory when the simulator restarts.

gently at first to test the waters or you'll lose prim to the pit at the edge of the sim. Make sure the object is physical before trying to toss it or it'll just move to the new location.
|
|
* shortened references
* Removed redundant 'this'
* Normalized EOF
|
|
* 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
|
|
* I stress, this is an initial implementation and the Agents(Child and Root) are definately obviously incorrect.

threadlocked code. ODEPrim was almost completely re-written.
Copy/Space test needed.
|
|
* All thanks to unimplemented packet listing :D
|
|
* 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.
|
|
* Experimental. Linux Prebuild needs testing.
* One more update after this to remove the ODEMeshing directory....
|
|
* 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.
|
|
* Added Angular Velocity reporting for smooth-ish rotations on object collisions

Much thanks to Gerhard!
Merged with Darok's recent changes re: physical prims

PhysicsActor and it's the ancestor for BulletXCharacter and BulletXPrim.Physical modifications: Changes for pass the value of Physical flag in the SceneObjectPart class to the Physics engines. New call for AddPrimShape so it has a new parameter called "isPhysical". The old call will be obselete soon (i believe). PhysActor and its descendants have a new property called IsPhysical. By the way no new special funcionallity added. It's more like preparing the way for new modifications.

all three physics plugins.
|
|
* Shortened type references
* Removed redundant 'this' qualifier

Have flattened the OpenSim.Framework project/namespace. The problem is that the namespace is still wrong as its "OpenSim.Framework" while the directory is "OpenSim\Framework\General" , so we need to decide if we change the directory or correct the namespace.
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.

not too much crouching). I think that we'll have to rethink what the
terrain resolution is down the road, as we don't really have enough sample
data to actually get people placed right on the land.

should equal project and directory.

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.
