writing f3d file

[Grace Lee]

When I run the snippet of code below (which btw is directly from f3d
documentation), I get this error : bool
Field3D::v1_1::writeFieldMapping(hid_t,
boost::intrusive_ptr<Field3D::v1_1::FieldMapping>): Assertion `io !=
0' failed.

// Create a scalar field to store a levelset
DenseField<float>::Ptr scalarField(new DenseField<float>);
scalarField->setSize(V3i(50, 50, 50));
scalarField->clear(1.0f);
scalarField->name = "character_head";
scalarField->attribute = "levelset";

// Note that the template type for writeVectorLayer<> is the
template type
// of the vector, not the vector type itself.
Field3DOutputFile out;
out.create("debugf3d.f3d");
out.writeScalarLayer<float>(scalarField);

I'm not sure why it's generating this error. Have you seen this error
before?

Thanks

Did you call initIO()? It might be that the standard IO classes
haven't yet been registered. I'll add a note for us to print a better
error message when that happens.

Hi Magnus,

Thanks for answering my question. The error is now gone thanks to your
suggestion.

Happy,
