SLF File Format

The main import/export file format for LifeMOD™ is called the SLF file. This ASCII file contains information on:

• units
• anthropometrics
• joints
• posture
• motion capture data

Units:

Anthropometric Data:

Joint Data:

Posture Data:

Motion Capture Data - Motion Agent Sets

Motion capture data consists of two blocks, a marker set and a motion data block. The marker set block indicates which marker location has available data. The ordering in the motion data block is dictated by the order of the marker locations in the marker set block. See appendix for motion data location descriptions.

Motion Capture Data - Augmentation Motion Agent Sets

Augmentation motion capture data consists of two blocks, a part set and a motion data block. The part set block indicates which part location has available data. The ordering in the motion data block is dictated by the order of the part locations in the marker set block. See appendix for motion data location descriptions.

Geometry File Format

Geometry for segments, such as bones, skin, etc. may be imported into LifeMOD™ by using the generic shell file format. Geometry files from many sources may be modified simply for inclusion in LifeMOD™.

The file format is a simple, one-header line followed by the vertices locations, and then the element topologies.

The vertex location is described by the metric system. If the data is not in meters, it should be converted or read using the units conversion number on the first line.
