Alright!

We ended up finding what was missing.
Whiile my new class type was well declared, it wasn’t registered to the PythonFactory, which handles the lookup of typenames to find out if the BaseData* object provided could be downcasted.

In order to get the new type registered, a call to SP_ADD_CLASS_IN_FACTORY(cvMatData,…[Read more]

Hi Lionel,

Thanks for your input!
I did that too. There are bindings for AssembledSystem in the compliant plugin, that is slightly different (it has a constructor and destructor, which uses a different SP_* macro.
But fundamentally, the implementation is the same:

1. a SP_DECLARE_TYPE(MyPythonType)
2. multiple static methods for python with the…[Read more]

Hi @hugo,

Thanks for your reply!

I investigated a bit further and found out a saveScreen() method in helper::gl::Capture.
This function does the screen grab (call to glreadpixels) in runSofa, but will not have the expected behavior in runSofa2.

For now, since runSofa2 is not yet fully implemented, I will use runSofa whenever I need this…[Read more]

Hi,

I finally have the solution to my problem:

In order to create template components in Sofa, there is nothing more to do than overloading the templateName() method, inherited from Base.
The templateName function must simply send back, for each template class, the name you want to use in your scene file, coma separated.

usually, your…[Read more]

Hi,

After a bit more research, I found out I over-complicated things:

I managed to get my templates working by templating my component over the source and destination type directly:

template<class SrcType, class DstType>

and for my own types (the cvKeypoint data structure) I implemented a DataTypeInfo as such:

template <>
struct…[Read more]

Thank you Hugo,

After discussion with some pro users, it happens that my problem is a fake problem:
in the scene example of my first post, I show an example where component 3 and 4 actually depends on the output of Node1 and Node2.

So logic would have that my components 3 and 4 would be in a subNode, whose parents are Node1 and Node2.

This is…[Read more]

Hi Jean-Nicolas

Thanks for your quick answer.
I tried what you said, but I got the same issue on windows. Though, I used CMAKE_PREFIX_PATH successfully on Linux, so it must be a CMake issue specific to Windows.

Does anyone have any idea why it wouldn’t work on Windows?
Cheers,
Bruno

Thank you Hugo,

I found a workaround for now (triggering scrot, a screenshooter utility) from python.
Though I think it can be a very usefull feature to add in Sofa. I will probably create a component for this in a near future 😉

Cheers,
