* The space bubble around a player's avatar is now visualized. When another avatar enters a player's bubble, The bubble visualization will appear, a soft tone will play, and the "Bubble" HUD button will flash.
* The space bubble radius setting has been removed. Space bubble size now scales based on avatar scale.
* Space bubble collision detection is now more accurate and reliable.
* CTRL + N toggles the bubble.
* The "Bubble" HUD button has been moved to the proper location.
Many render items/payloads contain smart pointers back to the
objects that added them to the scene, including entity and avatar
objects. Currently, those render items are destroyed when the
scene is destroyed very late in the application life-cycle.
There are rare crashes that can occur when these render items are
destroyed. Possibly, due to them referencing objects that have
already been destroyed via raw pointers. In an effort to
eliminate these crashes, we now destroy the scene earlier, within
Application::aboutToQuit() which is connected to the
QCoreApplication::aboutToQuit signal. Also, we guard against null
scene pointer dereferences. Any location that accesses the scene
off the main thread, now checks the validity of the scene pointer.
* Bug fix for eye tracking in HMD, the "up" orientation of your eyes now match your head.
* DebugDraw: added drawRay method.
* Application: Renamed preRender to postUpdate
* AvatarManager: added postUpdate method that iterates over all avatars.
* MyAvatar: Renamed preRender to preDisplaySide
* MyAvatar: split preRender code into postUpdate and preDisplaySide.
* Removed "Show who is looking at me", "Render focus indicator" and "Render lookat target" debug draw.
* Split "Show Look At Vectors" into "Show My Look At Vectors" and "Show Other Look At Vectors", to make it easier to debug eye tracking.
* "Show Look at Vectors" now draws the right eye red and the left eye blue.
* Removed Avatar and MyAvatar renderBody
* Removed look at rendering from head.
* GLMHelpers: Bugfix for generateBasisVectors when up primary and secondary axis were orthogonal
This extraordinary event can occur if a MessageBox is popped up by the opengl driver.
* removed AvatarData::avatarLock
* removed AvatarUpdate
This code was left over from an earlier avatar threading experiment.
Removed AvatarData avatarLock and AvatarUpdate class
Moved MotionState deletes out of PhysicsEngine.
EntityMotionStates are deleted by the PhysicsEntitySimulation.
AvatarMotionStates are deleted in the Avatar dtor.
The previous code inadvertently added a default constructed shared pointer
to the avatar hash, causing it to crash when dereferencing it in
the update loop.
