Re: No "Preview static pose" in version 3.3

Hi All, Well, it has been a while. In the above posts, I side-stepped the issue by using the API and the SimBody visualizer. Good short-term solution. But I've come back to the issue, and I solved my problem. I had multiple versions of OpenSim running, including versions build from source from the g...

Re: No "Preview static pose" in version 3.3

Hi All,

I've changed machines, re-installed v3.3 64bit and I also have the same issue Sarah mentions, where using 2392 I cannot preview .trc markers from the static trial using the preview experimental data option.

Weird no?

Re: Building OpenSim v3.3. from source, VS 2015

Hi All, I tried Ayman's suggestions about non-release builds, but it did not work. I re-made Simbody and OpenSim with VS 2013 compilers and now it works great. I have not tried Jim's suggestion about the upgrades but it sounds about right. Thanks all. Happy to try any new versions that are full 2015...

Re: Building OpenSim v3.3. from source, VS 2015

Hi Jim, Thanks for the suggestions. In short, I wanted to build from source for giggles and because it should be doable. As it stands, v4.0 will not work for some specific modelling software we use, but in the future perhaps. It could be a VS 2015 issue. I built from source with VS 2013, so I may ha...

Building OpenSim v3.3. from source, VS 2015

Hi All, I realize you have minimal time to support source builds, but here goes: I built Simbody v3.5.3 from source on VS 2015 with CMake 3.6.0. No issues. I downloaded OpenSim v3.3 source files from SimTk (why are they not on GitHub? Curious ;) ). CMake runs fine, VS does not. I'm running Windows 7...

Re: Detecting contact between non-analytical shapes

Hi Mr. Sherman,

Great!

That is a really informative answer.

If I end up implementing this through Simbody, I will keep you updated with the progress and maybe the eventual code would be of some use to the user community.

Best,

David

Re: Detecting contact between non-analytical shapes

Hi Mr. Sherman, Thank you very much for the quick reply. I have implemented a version of mesh contact detection in Matlab, but as it is a numerical approach with a lot of evaluations it is time consuming. I'm looking into methods to spline the point clouds and to evaluate contact analytically to mak...

Detecting contact between non-analytical shapes

Hi All, I am beginning a new project on femoroacetabular impingement. Briefly, this is a disease of the hip due to poor conformation of the head of the femur and the acetabulum. I am curious if Simbody is well suited to solving the following problem? 1) I have .ply files that are finely defined repr...

Re: Matlab crash afterI'm using model scaling using API

Problem solved. 1) I did not realize that somewhere in the scaleTool or modelScaler constructors the unassigned pelvis will cause a scale set of [1 1 1] to be generated. Not so for outboard bodies left unassigned. 2) I was then adding another pelvis scale to the existing scale set. 3) On top of that...

Re: Matlab crash afterI'm using model scaling using API

Hi Guys, A few other things I noticed. First, I'm using 64-bit Matlab 2015b and 64 bit OpenSim v3.3. I have the same issue using a 32b Matlab 2011a and 32b OpenSim v3.1. That is not exhaustive, but I doubt this is a version to version issue. Second, I commented out my section of code that creates a ...
