Theia's markerless motion capture technology can integrate with Visual3D and Sift since it exports c3d files. Various versions of Theia's software integrate with Visual3D and can be easily imported to further process, analyze, and visualize your data.

Key features of our integration with Theia include being able to import C3D files from:

1. Theia Axiom v2025
2. Theia Apollo v2024
3. Theia 2023
4. Theia 2022
5. Theia 2021

Typically, users want to merge Theia3D's motion capture output and analog signals such as force platform recordings. There is a retired pipeline command called Manage_Theia3D_Merge, instead Manage_File_Merge can be used.

This pipeline command makes it simple to merge markerless motion capture files from Theia with marker-based motion capture files from Qualisys QTM.
