Calling glm::axis() on an identity quaternion does not result in a normalized vector.
This vector was used within Rig::updateEyeJoint() to limit the rotation of the eye balls,
to prevent the eyes from rolling back into the avatar's head.
If the avatar was looking straight ahead, this could result in bad quaternions in the eye ball
joint matrices, which in turn would cause the eye ball mesh or any mesh influenced by the eyeball joints
not to render.
Previously we were using a infinitely tall vertical cylinder
to push hand IK targets out of the body, this had the
side-effect of preventing the hands from being raised over
the head. Now, we collide against the same 3d capsule
used by the physics system for avatar collisions.
There were three things that were causing issues with eye look at vectors while wearing an HMD.
1) The matrix returned by AvatarUpdate->getHeadPose() was in the wrong space, it should be in avatar space.
it was actually returning a matrix in sensor/room space.
2) The lookAtPosition was incorrect while wearing an HMD and with no avatars to look at.
3) The eye rotation limits in Rig::updateEyeJoint were relative to the model's zero orientation, NOT relative to the head.
this was causing the eyes to hit limits when the avatar head turned.
Now there are two sets of of jump takeoff and in-air animations.
* Run - Used when the character jumps or falls with a small forward velocity.
* Standing - Used when the character jumps or falls in-place or backward.
CharacterController
* increased takeoff duration to 250 ms
* increased takeoff to fly duration to 1100 ms
* added standing jump and in-air animations
* added 250 milisecond delay between ground and hover, to prevent going into hover when walking over cracks.
* take-off to in-air transitions now use the new snapshotPrev interp type for a smoother tweening.
This options are for for developers only and might help debug animation related issues.
* Enable Inverse Kinematics: this can be toggled to disable IK for the avatar.
* Enable Anim Pre and Post Rotations: this option can be used to use FBX pre-rotations from source avatar animations, instead of the current default, which is to use them from the source model.
This only effects FBX files loaded by the animation system, it does not affect changing model orientations via JavaScript.
Hand animations now have 5 states:
* idle
* open
* grasp
* point
* farGrasp
The handControllerGrab.js script now chooses one of these five animations, based on the state of the HandController object.
Also, removed hand trigger AnimVar setting from C++ Rig class.
This makes the accessible for controller mapping and to JavaScript.
Added 'neuronAvatar.js' as an example of reading joints from the neuron and setting them
on the avatar. NOTE: the rotations are currently in the wrong coordinate frame.
Is a subclass of Model, it overrides the updateClusterMatrices so it will pull
the actual joint matrices from a different rig override.
For the avatar soft attachment system, this override will be the Avatar::_skeletonModel rig.
This will give us the ability for an avatar to "wear" non-rigid attachments, such as clothing.
New JavaScript API to get the avatar's default pose.
MyAvatar.getDefaultJointRotation(index);
MyAvatar.getDefaultJointTranslation(index);
See `examples/tPose.js` for example usage
It can be called from script with minimal blocking,
because it inspects a copy of the joint values from the Rig, which is updated atomically.
This copy occurs in Rig::updateAnimations()
