        Still looking for the best way to do that. However, from first tests it is now possible to draw vectors over the video (yeah!) and based on the Tsai calibration method, the transformation between the camera coordinates and the world coordinates can be found only using the corners of the force plate (see QtCalib for an example: http://w3.impa.br/~zang/qtcalib/nochess.html).
        This was the main concerns to implement or not this idea. Now there is still minor problems (user interface for the calibration, storage of this calibration, calibration adatapted to the size of the view, etc.), but this idea will be definitively implemented in Mokka.

      • create a movie from view-panel

        it's would be more user-friendly than freeware like 'camrecorder'

          Mokka 0.6 will have an export function to create an image sequence from a selected 3D view. From this image sequence you can create a movie with for example the cross-platform software avidemux (http://fixounet.free.fr/avidemux/). Note: even if a dialog box will be on top of Mokka, you will be able to interact with the 3D view (to zoom, rotate, etc). It this implementation is enough for you, I will close this ticket.

              • Have the possibility to view and plot the metadata in a specific window

                (not linked to "points" number of frames)
                For example, if a store as a metadata the kinematics and/or kinetics parameters of a gait (normalized in % of gait cycle), I would likt to plot these data in a 0->100% graphs.

                • Subdivisions in the Model outputs

                  Possibility to have subdivisions in Models outputs rather than having directly "Angles", "Forces" ...
                  Example:
                  Model ouputs
                  > Condition 1
                  > Angles
                  > ...
                  > Condition 2
                  > Angles
                  > ...

                  Could be perfect for comparisons (of course without the use of the 3D view ...)

                                More than only saving the layout, save the data that as been dropped in each view for a fast reloading of the data.

                                    Dear Maria,

                                    To remove any possible confusion. The MOT file format which interests you is the one generated by SIMM or OpenSim? At this time, I do not have any MOT file. Could you sent me some of them to create the parser?

                                    Best regards,

                                    Mokka support team

                                      I don’t know the way to do this (have you to use Vicon iQ?) and Mokka is not (yet?) adapted to support the recording of data (circle buffer … as well as the visualization of realtime data. However It will be great to be able to plug Mokka to existing acquisition systems!

                                          The support of the BVH file format will be available only when the notion of “biomechanical model” will be fully implemented in Mokka. The core of the “Models” module is already implemented, but the user interface still needs to be modified in consequence. This will take time.
