Interpolators

[Maik Figura]

Hello, 

for my bachelor thesis I am doing some research intro Field3D Format, which so far is really amazing and good.

My question regards the interpolators mentioned in the doc: 

A simple interpolation example:
DenseField<T>::Ptr field = someField;
DenseField<T>::LinearInterp interp;
// Prefix indicates coordinate space
V3d wsP(0.0, 0.0, 0.0);
V3d vsP;
// Use mapping to transform between coordinate spaces
field->mapping()->worldToVoxel(wsP, vsP);
// Interpolation always uses voxel space
T value = interp.sample(field, vsP);

I tried using this example like this: 

 

 

... Field3D::DenseField3f::LinearInterp interp; interp.sample(someFieldA, vsP) ... 

 

and 

 Field3D::DenseField3f::CubicInterp interp; interp.sample(someFieldB, vsP) ... 

but in both cases, the sample function ('interp.sample') does not show up for me. 

Do I take it right, that one has to implement the sample function? I've noticed that 'Field3D::DenseField3f::CubicInterp' points to 'Field3D::CubicGenericFieldInterp' which defines a virtual sample function. 

I am a bit confused about this topic in the docs. Can someone please clarify this for me? 

Cheers

Hi, I think you just need to #include <Field3D/FieldInterp.h>. The interpolation classes are only forward declared in the field header files.

Ahhhhrg, 

youre probably right. Ill try this on monday. I totally forgot to check the include. 

Thanks, Ill post an answer on monday.

Cheers

Hey Magnus,

you where right. The include was indeed the problem. 

Thanks for the fast response. 

Cheers
