* 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.

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
|
|
* commenting out unused variables
|
|
|
|
added 44 configurable options!
* 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.

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.

Trimesh collisions should now work relatively efficiently. BulletX plugin should now be functional - feedback would be appreciated as to how it performs vs ODE.
|
|
collision into BulletX plugin. Additional work to come in the next few days.

not the attachment.

* Nothing user facing yet.
|
|
* Made a bunch more members static, removed some dead code, general cleaning.
|
|
* 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
|
|
(this took a while to run).
|

|

|
|
* 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.
|
|
Changed LogBase to ConsoleBase, which handles console I/O.
This is mostly an in-place conversion, so lots of refactoring can still be done.
|
|
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.
|
|
been an update on bullet in a while and the console notifications consume the entire CPU to make bullet completely unusable.
|
|
* 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.
|
|
* 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.
|
|
* I stress, this is an initial implementation and the Agents(Child and Root) are definately obviously incorrect.
|
|
notice of doom
|
|
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.
|
|
sends terse updates when needed.
* 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.
|
|
* Added Angular Velocity reporting for smooth-ish rotations on object collisions

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