Re: OpenSim Tutorial 1 error

Hi Jason, Considering that we literally have hundreds of students using the tutorial without an issue, I suspect that the problem lies with the instructions you received to run the tutorial rather than with the tutorial itself. If you can provide more context as to what version of the software you'r...

Re: Configuration MATLAB/OpenSim - Error Java

Hello, While the steps to hookup Matlab with OpenSim are a bit error prone, once you have it working it should continue to work. There are a couple issues though that you have to keep an eye on: 1. What version of OpenSim you used to perform the hookup? you generally can't change the version or the ...

Re: Erroe: Failed to load OpenSim Libraries

Hi Deepak, While a little bit surprising, it's not totally unexpected because of the way Windows resolves libraries/DLLs based on one single common PATH environment variable. What likely happened is that 3.3 added the path to the 3.3 distribution to the front of the common PATH environment variable ...

Re: C3DFileAdapter is Undefined

Hi Davide, Within C++, there're some settings and files/directories that need to be included at the top of the source file e.g. OpenSim/OpenSim.h if working with a distribution or the full path OpenSim/Common/C3DFileAdapter.h, and the paths need to be searched by your project build files etc. If you...

Re: Import cad model

Hello, CAD models as much as OpenSim models contain not just the geometry/meshes that you see visually, they also contain other info: Joint definitions, Constraints, possibly forces, controllers, .... As such there's no universal format to transfer arbitrary CAD models into OpenSim or into any other...

Re: Scale Model error(step 3: Placing markers on model)

Hi Lee, Can you do the scaling without placing markers? At least this will help us identify the problem area. From there it's an IK problem utilizing some fixed/anatomical markers followed by moving the non-fixed markers. Note that to solve the IK problem the model needs to be able to move/adjust co...

Re: OpenSim Scale Issue

Hello, My recollection is that this was an issue with visualization rather than scaling due to the fact that the model uses custom geometry/mesh files that the scaled model can't find. If you save the scaled model in the same folder as the original/pre-scale model and reopen it, it will display corr...

Re: OpenSim in Unity

Hello, 1. Can you explain specifically what does not work and how? Generally when mixing or loading libraries/dlls from one system into another you need to know the specific compiler version/settings/runtime. Do you need to run OpenSim live in the loop or can you interact with it through command lin...

Re: Opensim for use with XSENS

Hello, Can you step back a second and explain why you're trying to convert timeseries data (as represented by c3d file) into an XML file that contains fixed marker locations? What is your planned workflow? Typically the markers live on different segments/frames of the model while the c3d data is all...
