Character Studio Marker (.csm)
The CSM (Character Studio Marker) file extension is associated with Autodesk's Character Studio, a component of the 3ds Max software. This file format is used to store 3D character position markers, which are essential for animating biped characters in motion capture data. Introduced in the late 1990s, CSM files are ASCII text files that contain raw marker position data generated by motion-capture devices. These files facilitate the accurate alignment and calibration of character models, ensuring realistic animation sequences. Character Studio Marker files have been instrumental in advancing 3D animation and motion capture technology, providing a standardized format for storing and manipulating character motion data.
