 |{{:V3D_Composite_wiki.png}}|The V3D_Composite pelvis refers to a pelvis segment created by C-Motion which is a variation on the [[Visual3D:Documentation:Modeling:Segments:Coda_Pelvis|Coda Pelvis]]. The pelvis segment is defined using the anatomical locations of the ASIS (Anterior Superior Iliac Spine) and the PSIS (Posterior Superior Iliac Spine). These landmarks are bony protuberances on the Pelvis bones that can be palpated on most (but not all) subjects. They are particularly useful if the subject is very thin, a cadaver, or a skeleton, and historically have been the reference points for defining the segment coordinate system for many experimental studies focused on determining regression equations for locating the hip joint centers. **Unfortunately, these landmarks are not easily palpated, or more importantly, cannot have motion capture markers placed accurately on them, for overweight subjects.**|
