+ | The coordinate system used by the model based items is precisely the coordinate system you see in the animation viewer.

- | ===== sign convention ===== | + | In order to get the signs of the COP_MODEL_COG to be consistent between the left and right leg (e.g. how to get around the fact that Visual3D enforces the right hand rule), you can select the check boxes in the dialog to negate one or more components. |
