BlendArMocap

BlendArMocap is a tool preform markerless tracking within Blender using Google’s Mediapipe. The main goal of the add-on is to efficiently transfer the generated detection results to rigs.

For more information, please refer to the documentation.

Features

• Detection of Mediapipe detection results in stream or video
  • Calculation of rotations for mediapipe data
• Import of Freemocap mediapipe session data
• Transfer tracking data to rigs and generate new transfer configurations
  • currently, officially supports the transfer to generated rifigy rigs

Mediapipe Detection

Run Mediapipe within Blender to detect pose, hand, face or holistic features. BlendArMocap calculates rotation data based on the detection results at runtime to drive rigs.

Caution: Requires external dependencies which can be installed via the add-on preferences with elevated privileges.

Freemocap import

Freemocap session data can be saved in a session folder which then can be imported using BlendArMocap. To import session data to blender, set the path to the session directory and press the import button.

Transfer

Currently there's a preset configuration to transfer detection results to generated humanoid rifigy rigs. To transfer, just select the generated humaniod rig as transfer target and press the Transfer Button. The transfer is based on mapping objects which you can modify. The modifications you can save as own configurations.

You'll find the mapping objects in the collections generated while tracking such as cgt_HANDS. Mapping instructions are stored as object properties and can be modified in the object data properties panel (where the constraints live). Here the concept of mapping objects:

mapping_object: object with instructions and constraints
driver_object: generated driver based on instructions
target_object: copies values from driver_object via constraints

If you happen to create a configuration to support another rig, feel free to send it to me for sharing via [email protected].
