model degrees-of-freedom ...

Dear OpenCap team, In the future, will the possibility exist to contribute different models to the OpenCap system? It's probably not necessary to say this, but some people require models that have a lot of detail at the neck, or the lumbar spine, or the hands. Obviously it's probably not desirable t...

data privacy ...

Dear OpenCap team, I'm working in Germany where data privacy is a very big topic. To that end: 1. Are the recorded videos processed by the webserver? Or is the video processing done on the local machine? 2. What data is sent out over the web? Is it sent over SSL? Is the security certificate of the s...

maximum number of cameras?

Is there a maximum number of cameras that OpenCap can support? If there is no limit, what is the highest number of cameras that have been used so far?

I'm *very* excited about OpenCap! The possibilities!

Re: CMC error in relation to fiber length

Dear Namwoong, I've taken a quick look at the exception that is being thrown, at Catelli et al., and at Catelli-V4.0_Nu.osim for a hint of what might be causing the problem. There are two things you can try modifying in the muscle model settings that may stop the exception from being thrown: 1. The ...

Re: Error with force velocity curve in Millard_equilibrium model

Dear Saurabh, The problem on lines 138-141 of Millard2012EquilibriumMuscle.cpp in Millard2012EquilibriumMuscle::extendFinalizeFromProperties: - if the eccentric_slope_at_vmax or concentric_slope_at_vmax are less than 0.1 they are set to this minimum - this update, however, is made without also updat...

drawing objects to the GUI from a C++ file

Hello, I would like to draw some geometry to the GUI but from a C++ file (main/plugin/api object). Is there a standard way to do this? If not, should I try a work around? I could probably get what I want by adding a free body to the model and then use a custom constraint to force the body to assume ...

Re: Segfault on initSystem

Thank you for the explanation Chris - that helps a lot. Using the command 'ldd' in linux I got a list of the dependencies - see below (I've built the target in Debug). Do you see a similar list when you run dependency walker? Should I be concerned that it appears that both the release and debug vers...

Re: Segfault on initSystem

Indeed I do have to keep the pointers: putting Simbody.h in the header causes conflicts with the other libraries I'm using. I've built OpenSim and Simbody in debug and rebuilt the project in debug. Oddly it looks like my program is linking against the non-debug versions of the OpenSim libraries. Thi...
