[SOLVED] Available objects in the factory (python or xml)

[jjcasmar]

I am trying to create some SOFA scenes , but I’m having some trouble trying to know the name of the objects or the properties it has.

In python for example I have:

def createScene(node):
    node.addObject("GridMeshCreator", resolution=[2,2])

I copied this from a .scn file

 <GridMeshCreator name="loader" filename="nofile" resolution="2 2" />

but its not clear at all what all the available properties for a particular object, which objects are available in the factory (and which with templates) and what type each property is. For example, in the GridMeshCreator example, resolution in .scn is a string but in python is a list.

It would be nice to have documentation to know object names, available templates, properties and type of property.

Hey Juan José,

You are right, it is not simple to have a global idea of the available components and their templates/datas. In my case, I always have the source code of Sofa close and look at the constructors of the component for which I want to see their data. The available templates are usually in the .cpp of the component (looking for RegisterObject calls).

I think it would not be too hard to implement a python bindings that look through the object factory of Sofa and gives you the list of registered components and their template, I’ll have a look at this.

For the data values requiring a list, it is up to you to give a string or a list. For example, both

node.addObject("GridMeshCreator", resolution="2 2")

and

node.addObject("GridMeshCreator", resolution=[2,2])

should work.

Thanks for your feedback !
