Scaling opensim
WebJun 19, 2024 · For SIMM models, this vector is always the zero vector (i.e., the body reference frame coincides with the joint). -->. . The scaling step scales the mass properties (mass and inertia tensor) of the model, as well as the dimensions of the body segments. Many of the elements attached to the body segments, such as muscle actuators and wrapping objects are also scaled. The scaling algorithm uses a multi-stage process and each stage … See more Scaling is performed based on a combination of measured distances between x-y-z marker locations and manually-specified scale factors. The marker locations … See more After scaling the model, the next step is to move the model's markers to match experimental marker locations in a static pose. The static pose is computed by trying … See more
