This Y_180 flip is defined in skeletonModel not in the rig.
This is important if we wish to use the Rig for both Avatars (180 flip) and Entity models (no 180 flip).
We can hide this 180 flip from script, if we wish, by including it in all the accessors to and from
MyAvatar -> skeletalModel -> Rig.
Added Quaternions::Y_180 to GLMHelpers.
* No longer normalizing scale in AnimSkeleton and AnimClip
This means graph is animating in 'geometry' coordinates
before unit scale is even applied. This is necessary to
properly work with both Avatar based models and ModelEntity
based models
Many things are broken.
* debug rendering (translations are x100)
* IK hand targets
* follow cam
* I did not even dare to try HMD mode
Except for SkeletalModel::computeBounds() JointStates are now completly
encapsulated by the Rig. Now we can start using AnimPoses instead and
in parallel with the JointState implementation. Then we can assert that
they are identical, before removing JointStates.
This check in has many comments with the AJT tag.
Each one of these cases will need to be revisitied and fixed.
In particular // AJT: LEGACY will be used to enclose all code
in the Rig which manipulates the _jointState QVector.
* Deleted AnimationHandle class
* Removed enableAnimGraph and anableRigAnimations from Menu.
* Removed *some* references to old IK system.
But it is still used when computing collision bounding volumes
Also moved Rig::updateAnimations() now occurs after
Rig::updateFromHeadParameters() and Rig::updateFromHandParameters().
This should remove a frame of lag for head and hand IK targets.
Rig::updateFromEyeParameters() occurs after Rig::updateAnimations().
But now the eye JointStates are re-computed, this is the actual
fix for the local eye tracking issue.
The main fix for this was to set the JointState animation priority to 3.0
The secondary fix was only noticed when we changed the animation priority
Basically, the debugRendering was using the JointStates after they were
manipulated by SkeletonModel to 'relax' them toward thier default pose for
IK purposes.
This is a blend of the previous 'sitting' and 'standing' HMD modes.
Basically, when you move your head within a small range (20cm) your
avatar will lean appropriately, however when you cross that threshold
your body will move underneath you, re-centering your head above the body.
While this occurs the avatar should play the appropriate walking animations.
Because the current IK system doesn't quite handle what we need
for the head and neck IK, we do it procedurally in the rig, and
manually set both neck and head IK targets.
