Re: How to display the path of a customized actuator in the gui?
I want to create a McKibbenActuator under api 3.3. Do I need to compile and build all the source code of opensim 3.3 after I create the actuator? Or should I add the McKibbenActuator.cpp and McKibbenActuator.h to under the main.cpp that I create to do a simulation?(I want to visualize my model in Op...

So I was wondering how to display the path of a customized actuator created by myself. Do I need to write some related code when I create my own actuator or ...

How to modify the CoordinateSet
Hi, all! I am trying to define a custom joint using OpenSim API 3.3 and create a similar arm to Arm26 which is one of your offical models. In the arm26.osim file, no matter how I modify my code, I just can't modify the CoordinateSet. Here's my code. CustomJoint* shoulder = new CustomJoint("r_shoulde...

Re: How to define the coordinates under TransformAxis?
I just find the answer.
Code: Select all
OpenSim::SpatialTransform shoulderST;
shoulderST.updTransformAxis(0).setAxis(Vec3(-0.05889802, 0.0023, 0.99826136));
shoulderST.updTransformAxis(0).setCoordinateNames(Array<std::string>("r_shoulder_elev", 1));- Mon Jul 24, 2017 6:33 pm
