-=-=-=-=-=-=-=-=-=-=-=-=-=- 3D Physics: -Fixed "Bounce" parameter in 3D -Fixed bug affecting Area (sometims it would not detect properly) -Vehicle Body has seen heavy work -Added Query API for doing space queries in 3D. Needs some docs though. -Added JOINTS! Adapted Bullet Joints: and created easy gizmos for setting them up: -PinJoint -HingeJoint (with motor) -SliderJoint -ConeTwistJoint -Generic6DOFJoint -Added OBJECT PICKING! based on the new query API. Any physics object now (Area or Body) has the following signals and virtual functions: -input_event (mouse or multitouch input over the body) -mouse_enter (mouse entered the body area) -mouse_exit (mouse exited body area) For Area it needs to be activated manually, as it isn't by default (ray goes thru). Other: -Begun working on Windows 8 (RT) port. Compiles but does not work yet. -Added TheoraPlayer library for improved to-texture and portable video support. -Fixed a few bugs in the renderer, collada importer, collada exporter, etc.
