Why we like it

Stands out in the superhive library because it connects Blender to the open-source Pose2Sim pipeline, importing camera calibration, markers, and OpenSim data and supporting markerless rigging, all under a permissive MIT license.

What is Pose2Sim Blender?

Pose2Sim Blender is an add-on for visualizing Pose2Sim results inside Blender and rigging a character with markerless kinematics. Pose2Sim itself is an open-source pipeline for obtaining research-grade 3D motion analysis from consumer-grade cameras such as phones, webcams, and GoPros.

Inside Blender, the add-on imports and displays several data types from that pipeline. It reads camera calibration from a .toml file, markers from .trc or .c3d files, and OpenSim data including .osim models, .mot motions, and .mot forces. It also bundles camera tools, OpenSim imports, and other utilities.

The add-on is documented for both a quick install and a full install, and its documentation also explains how to cite the project and how to contribute. It is released under the MIT license and listed for Blender 4.0 and 3.6, with the source code available on the developer's GitHub page.

Who is Pose2Sim Blender best for?

Pose2Sim Blender is best for working with Pose2Sim motion analysis data in Blender — visualizing camera calibration, markers, and OpenSim results, and rigging a character with markerless kinematics.

How much does Pose2Sim Blender cost?

Pose2Sim Blender is completely free to download and use.

Frequently asked questions

Which Blender versions does Pose2Sim Blender support?

Pose2Sim Blender is listed for Blender 4.0 and 3.6. If you run one of those versions, you can install it through either the quick install or the full install route described in its documentation. The add-on's source code lives on the developer's GitHub page, which is the best place to confirm any additional version details or setup requirements before you install it.

What file formats can Pose2Sim Blender import?

Pose2Sim Blender reads several file types produced by the Pose2Sim pipeline. It imports camera calibration from a .toml file, markers from .trc or .c3d files, and OpenSim data including .osim models, .mot motions, and .mot forces. Alongside these imports it provides camera tools and other utilities, so you can bring calibration, marker, and OpenSim results together inside Blender for visualization and rigging.

Is Pose2Sim Blender free to use?

Pose2Sim Blender is listed as free here and released under the MIT license, which is a permissive open-source license. For the most current licensing terms and any usage conditions, check the developer's page and the GitHub repository. The source code is publicly available there, and the documentation also covers how to cite the project and how to contribute if you want to get involved.

How do I install Pose2Sim Blender?

Pose2Sim Blender comes with documentation describing two installation paths: a quick install and a full install. Both are covered in the project's documentation on the developer's GitHub page, which is the recommended reference for setup steps. That page is also where the add-on's source code lives, along with notes on how to cite the project and how to contribute. Check there for the current instructions before installing, since the documentation is maintained alongside the code itself.
