Summary:
missing python wrappers for some SimTK classes?

Detailed description
Hello, I am using python wrappers of opensim to build my models, and I have some issues while writing my scripts. Indeed, I need to create some 'SimTK::Transform' for positioning geometries, and I need a 'SimTK::Rotation' and a 'SimTK::Vec3' to instantiate my class. The problem is 'SimTK::Rotation' seems not to be available in the wrappers. By searching in the source file "OpenSim/Wrapping/Python/swig/pyWrapOpenSim.i", it seems that <SWIGSimTK/Rotation.h> and <SWIGSimTK/CoordinateAxis.h> are never included. If it is not made on purpose, I guess it is sufficient to add in "pyWrapOpenSim.i" something like: """ // Rotation %include <SWIGSimTK/Rotation.h> namespace SimTK { %template(Rotation) SimTK::Rotation_<double>; } %include <SWIGSimTK/CoordinateAxis.h> """ Best regards,

Date: 2014-10-15 17:14 Sender: Ayman Habib Hi Joseph, Excellent find, here's the section of the .i file we use for Java wrapping (that should've been in the python interface file as well) .... %include <SWIGSimTK/SpatialAlgebra.h> namespace SimTK { %template(SpatialVec) Vec<2, Vec3>; %template(VectorOfSpatialVec) Vector_<SpatialVec>; %template(VectorOfVec3) Vector_<Vec3>; } %include <SWIGSimTK/CoordinateAxis.h> %include <SWIGSimTK/Rotation.h> namespace SimTK { %template(Rotation) SimTK::Rotation_<double>; %template(InverseRotation) SimTK::InverseRotation_<double>; } // Transform %include <SWIGSimTK/Transform.h> .... Will fix in the next release but you can make the edits above to the interface file and get going. Best regards
