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. The Manage_File_Merge command is designed to merge multiple files that recorded data from the same motion capture trial. This command merges data types from each .c3d file into one trial in the Visual3D workspace. This command was originally called Manage_Theia3D_Merge, but since has been updated to be used for file types other than from Theia3D. This pipeline command makes it simple to merge markerless motion capture files from Theia with marker-based motion capture files from Qualisys QTM.

The following sample data can be used to follow along with the outlined steps in Merge Theia with QTM Analog Data
