* Fixes recognizing when a sit target is and isn't set.
* * 1. Vector3.Zero.
* * 2. Orientation: x:0, y:0, z:0, w:1 - ZERO_ROTATION
* * (or) Orientation: x:0, y:0, z:0, w:0 - Invalid Quaternion
* * (or) Orientation: x:0, y:0, z:1, w:0 - Invalid mapping, some older objects still exist with it

this for each region in your Regions.ini[PhysicalPrimMax = 10(default)])
* Adds a configurable maximum object mass before the mass is clamped. Default is 10000.01. Configurable by changing maximum_mass_object in the [ODEPhysicsSettings] section.
* Clamping the mass is important for limiting the amount of CPU an object can consume in physics calculations. Too high, and the object overcomes restitution forces by gravity alone. This generates more collisions potentially leading to 'deep think'.

linkset where EnableBody was called and the body is immediately disabled. The previous functionality assumed that a body was received in EnableBody but.. in some cases, it wasn't.

avatar. This prevents the 'double jump' capability that's been occurring for ages when avatar collide with prim on the side.

dragged a prim, in some cases, it would corrupt the datatype in memory and throw spurious IndexOutOfRangeExceptions.
* Physics a situation that causes physics to spew redline messages to the console forever.

normally again.

one fixes the situation where the object on the server is moving but no updates are being sent.

last week, change av_capsule_tilted to false by default
This appears to now give better ODE physics response (less sinking into the ground, etc.)
Please change it back if this is actually a bad idea for some reason

* Change the PhysicsCollision callback for objects to send full contact point information. This will be used to calculate the collision plane for avatars
* Send the physics engine velocity in terse updates, not the current force being applied to the avatar. This should fix several issues including crouching through the floor and walking through walls

drifting prims/avatars
* Added contacts_per_collision to the ODE config section. This allows you to reduce the maximum number of contact points ODE will generate per collision and reduce the size of the array that stores contact structures

checking for velocity in certain directions, and was calling the get_Velocity() function three times)

The scene is still the one reporting dilation so this does not break the API or remove flexibility, but it gets the calculation happening in the right place for the normal OpenSim usage. The actual calculation of physics time dilation probably needs tweaking

dictionary to store unique meshes in Meshmerizer based on creation params. This patch contains a dictionary to map each of those unique meshes to its ODE TriMeshData. This eliminated hundreds of megabytes of memory consumption in the unmanaged heap when there are lots of the same prim (roof tiles, bricks, siding, decks, chairs, etc). The objects do not need to be physical to benefit from this patch.

track threads once the first call to UpdateThread() has been made, and allow re-tracking of threads that timed out but revived later
* Added a commented out call to Watchdog.UpdateThread() in OdeScene. If it turns out that loading a large OAR file or some other operation is timing out the heartbeat thread, we'll need to uncomment it

Inconsistent locking of ODE tainted prims

consistent with the rest (and so chi11ken's auto copyright adding script doesn't duplicate the copyright.

relogging.

scenepresence that there was an issue so it doesn't try to make the capsule again. I have a feeling that this is some kind of object leak. We'll know for sure.. soon.

it will definitely get us closer to the root cause.

|
debugging easier. Without this, from the user's perspective.. they cannot move, fly or otherwise do anything physical and without a message on the console, it would be hard to tell that this is what is occurring.

allocate memory, and therefore the unmanaged wrapper call fails or worse.. there's some unmanaged resource accounting in the ODEPlugin for ODECharacter that isn't being done properly now.
* The broken avatar may not be able to move, but it won't stop simulate from pressing on now. And, the simulator will try to destroy the avatar's physics proxy and recreate it again... but if this is what I think it is, it may not help.

enabled, the first Heartbeat loop call to UpdatePhysics takes 20 minutes. 75% of that time is spent in this sleep. (100k prims * 10ms)
|
|
ScenePresence.AddToPhysicalScene.
* This causes time to be counted in ODECharacter and, when a collision occurs, the physics scene will report the collisions only if the the difference of last time it reported the collisions from now was more then the set ms.
* This is cool because the time accrues while collisions are not taking place and when they do take place again, you get an immediate update.
|
|
* Set the Scene collision update time to 500 ms

allocated on the unmanaged heap. This prevents fragmentation of the managed heap and the resulting stress on GC. A region with ~150,000 prims using ODE and Meshmerizer saw memory remain flat around 1.2GB as opposed to 1.5GB and continually growing due to pinned memory. This patch complements the unique mesh dictionary patch applied to Meshmerizer but is independent. The net effect is a 60-75% reduction in memory for our largest regions.

parameters. CreateMesh() returns a Mesh from the dictionary or creates a new Mesh if it has not been created before. Meshes are never purged from the dictionary. The raw Mesh data is discarded once the memory is pinned for ODE use. All copies of the same prim/mesh use the same pinned memory. ONLY IMPLEMENTED AND TESTED WITH MESHMERIZER AND ODE
