I was wondering: how can I let the trigger volume for GRF prediction follow the foot also in the normal direction? At the moment, it only follows the CoP on the level ground plane, but I would like to experiment with GRF prediction in multi-level trials.
Is there an easy way to accomplish this?
I don’t think there is a easy way to do this. Also note that it is just a visual thing when you say the trigger volume appear to be following the foot in the horizontal direction. The trigger volume is basically just a fixed plate/floor of very large size. It is only the visualization that follows the foot.
I think you can change the implementation so the plate has a limited size or shape. Maybe you can then add more plates at different heights to represent stairs etc. Sorry, it is not really something which we have tried.
@msan00 Have any of your students ever done something like this?
Hi Marco and Morten
I think it is in principle possible to make but comes with a limitation worth thinking about. Currently, the contact is detected by two conditions: 1) the node is close ground and 2) the vertical velocity is close to zero.
If you want to allow the plate to move vertically automartically, you cannot use condition 1 anymore. Hence, you would get contact anywhere in space when the velocity is low. Whether that will work for your application, I do not know.
Thank you. Yes, I also thought about that, but I could not easily predict whether that would make sense for the activities we have. For now we decided to prioritize other activities that occur mostly on the level-ground.
