This will allow us in the future to pull preRotations from
animations instead of the model skeleton. It is disabled
by default because our current animations preRotations are
not correct for the left hand.
This makes it much simpler for code out side of the rig to manipulate AnimVars
* Removed mat4 type from AnimVars
* AnimVariantMap now has a _rigToGeometryTransform matrix
used to transform positions and rotations into the correct coordinate frame.
* Moved AnimPose code to extract a quat from a scaled matrix into GLMHelpers
* Moved JointData into shared library
* added methods to the rig to copy into and out of JointData
* JointData translations must be in meters this is so the
fixed point compression wont overflow, also, it's a
consistent wire format.
* 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
Changed default eye position to 1.9 meters because
the hifi_team avatars are 2.0 meters tall.
Also, prevent array access with negative indices when eye bones are missing.
ಠ_ಠ
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
This should fix the issue with the hips moving erratically when arm IK
is enabled. The main issue is that the IK system assumed that the "Hips"
joint was the root of the skeleton. For Blender avatar this is not the case
as it inserts an "Armature" node at the root instead.
