AMMR v.3.1.4

AMMR 3.1.4 (2025-09-03)

🩹 Fixed:

• Refactored references in the hand model so BVH MoCap models can share the same
  marker protocol regardless of whether the detailed or simple hand is enabled.
• Updated the subscapularis insertion to the lesser tuberosity, improving its
  moment arms during humerus internal rotation. Special thanks to researcher
  Margaux Peixoto (Laboratoire d'Innovation ETS, Montreal) for contributing this
  enhancement to the shoulder model.
• Fixed contact thresholds in the Leg Press Machine example to ensure contact with all nodes.
• The `joint strength evaluation models now
  use the "MinMaxAux" muscle recruitment solver, improving robustness without
  changing results.

➕ Added:

• Refactored the implementation of the pelvis rotation vector measure in the
  interface folder to allow overriding the global reference frame.

AMMR v.3.1.3

AMMR 3.1.3 (2025-06-16)

🩹 Fixed:

• Fixed a regression in the VideoLookAtCamera VideoTool that prevented
  animated GIFs from being created when the video source was not an .mp4
  file. It now supports any video format compatible with the ffmpeg library.

🔧 Changed:

• The intermediate joint angle files used in MoCap models now have headers
  which reflect the original output measure instead of the variable name in
  the output class. This is useful if the files are used for anything other
  than transferring the joint angles from marker tracking to inverse dynamics.

➕ Added:

• Two new outputs have been added to the JointAngleOutputs folder in the
  MarkerTracking study in MoCap models:

  • JointAngleOutputs.AllDoFs.Values
  • JointAngleOutputs.AllDoFs.Names

  These variables contain the values and names of all joint angle variables
  saved during marker tracking. They provide an alternative way to access the
  same intermediate joint angle values that AnyBody writes to files when
  running marker tracking.

AMMR v.3.1.2

AMMR 3.1.2 (2025-06-02)

This release of AMMR contains an important fix to the robustness of the MoCap models.
If you experienced problems with kinematic errors when running inverse dynamics then
please update to this version.

🩹 Fixed:

• Improved how kinematics calculated in marker tracking is applied
  to inverse dynamics MoCap models. The previous
  method for applying joint angles from marker tracking could sometimes
  struggle with complex rotations (gimbal lock situations). The updated
  implementation enhances the stability of the kinematic solver, particularly
  for numerically large pelvis rotations, leading to more reliable motion analysis.

  TL;DR: The implementation was previously using AnyKinMeasureLinComb to
  enable adding a pelvis offset. This had the side effect that the kinematic
  engine had to assume small angles, and thus, had difficulties handling
  large rotational quantities (e.g. +/- pi, 2pi) for pelvis rotations.
  The new implementation only includes the 3 pelvis positions in the
  AnyKinMeasureLinComb instead of all trunk angles. This makes the kinematic
  solution more robust for large rotational quantities, which typically may arise
  for pelvic's global orientation.

AMMR v.3.1.0

AMMR 3.1.0 (2025-03-31)

🔧 Changed:

• Modified the Human-Ground residual implementation in MoCap models to use
  rotational measures configured for angular velocities. This change enhances
  the robustness of the residuals and makes the residual output easier to
  interpret geometrically, without affecting the results.
• Updated the insertion and origin points of the Gluteus Medius to ensure
  correct moment arms for external rotation in specific postures. The posterior
  Gluteus Medius now twists inside the anterior part and attaches more
  anteriorly on the femoral trochanter.
• The wrapping surface for muscles at the wrist has been changed from a cylinder
  to an ellipsoid. This lowers the risk of muscle via points penetrating the
  wrapping surface in postures involving both flexion/extension and
  abduction/adduction at the wrist.
• Excluded force plates from the parameter identification study, as they were
  unnecessary. This change may slightly speed up the parameter identification
  process.
• The coordinate system used when scaling the shank segment has been aligned
  with same reference frame used when scaling the thigh segment, instead of
  using the anatomical frame of the shank. Now both segments use the direction
  given by the femoral epicondyles as the lateral direction. This change
  ensures consistent scaling across the knee joint.

➕ Added:

• Introduced a new class template,
  CreateCoMRefNode,
  for generating a reference node at the center of mass of a segment, aligned
  with its principal axes of inertia.
• Added the TRI(N) macro to create a lower triangular (NxN) matrix.
• Added the TOTAL_POLYLINE_LENGTH(P) macro to compute the total length of a
  polyline defined by a set of points.

🩹 Fixed:

• Corrected the PelvisGround rotation drivers in the {ref}Free Posture Static example<example_freeposture>. The X and Z rotation drivers were previously
  mixed up and are now properly assigned.
• Resolved an issue that prevented disabling the drawing of marker arrows in
  CreateMarkerDriverClass within MoCap models. The search string in
  Main.ModelSetup.Views.All_MarkerArrows.Objects has been updated to correctly
  identify the arrow drawing objects.
• Fixed a spelling typo in the disc stiffness BM control statements. The
  BM_TRUNK_*_DISC_STIFNESS parameters have been renamed to BM_TRUNK_*_DISC_STIFFNESS.
  The misspelled parameter names have been deprecated.
• The data points for the femoral epicondyles with respect to the shank in the
  neutral posture have been corrected. These values were not updated when the
  knee axis in shank was redefined in TLEM 2.2 and AMMR 3. This change has no
  influence on the default AnyBody Models, but it fixes an issue if the model
  was configured to use the {bm_constant}special 'bony landmark' defined <_JOINT_TYPE_BONY_LANDMARK_>
  joint axis configuration.

Removed:

• Removed the python hooks to check for modified AMMR folder. This feature was
  not used and has been removed to simplify the AMMR codebase.

AMMR v.3.0.4

🩹 Fixed:

• Fixed an issue in the Bike Model example that included thoracic support in the full body model also.
• Fixed an issue with the visualization of the marker coordinate system arrows. They now
  correctly update while running running parameter identification in the MoCap models.

AMMR v.3.0.3

AMMR 3.0.3 (2024-06-10)

This is a minor release of the AnyBody Managed Model Repository.

🩹 Fixed:

• Fixed a penetration warning for the pectoralis muscles when the thoracic
  segments are scaled very non-uniformly. The fix involves a small (5 deg)
  adjustment to the orientation of the pectoralis wrapping surface.
• Fixed default limits in Range of Motion limits
  class template. The default limits for PelvisThoraxExtension, PelvisThoraxLateralBending,
  Right/LeftWristFlexion had the upper and lower limits flipped. This is now fixed and a
  check is added in the class template to catch this kind of error.
• Fixed an issue where blinking Windows would appear when loading models stored
  in git repositories. This issue was caused by a python subprocess that queried
  the git repository for branch information.
• Updated the foot marker position in the Xsens protocol to accommodate the
  changes made to the foot anatomical frame in the TLEM 2.2 leg model. The
  R/LTOE and R/LTOE2 markers have been moved upwards by 1.5 cm.

AMMR v.3.0.1

This minor release of AMMR contains no updates to the models compared to the major AMMR 3.0.0 released the previous month. It only has a few minor changes to the documentation and new tolerances in the FDK models.

🔧 Changed:

• Finer FDK tolerances for the Knee Simulator example, to take advantage of the improved robustness of the
  AnyBody FDK solver in version 8.0.1.

AMMR v.3.0.0

See the changelog for information on what is included in the release.

✨ Highlights:

• Integrated pelvis, lumbar, and thorax models into a consistent trunk model in preparation for a full thoracic model in AMMR 4.
• Updated the leg model (TLEM 2.2) with improvements to the ankle complex, shank orientation, and alignment of the patella tendon.
• Added new wrapping surfaces to the Achilles tendon around the ankle in the TLEM 2.2 leg model.
