Pushed some code to a branch named vbap_style_interpolation. Here is the example from above. (The upper point actually gets a weight of zero. Just the markersize has an offset.) ```...

(This is in fact VBAP if all points lie on a sphere.)

Sorry, I made a mistake in these examples: I compute the triangulation via the 3D convex hull. For this to work, the origin must be contained in the convex hull....

As an example, let's assume a grid which covers only a spherical cap around the northpole (of the unit sphere). Then origin is outside the convex hull. Two kinds of...

Maybe the delay line should be responsible if it needs zero-padding?

Same thing with `driving_function_mono_wfs_ls()` and `greens_function_mono()`. It would be nice to do this in a consistent way, but there will be some difficulties: With the driving functions, `xs(3:6)` indicates orientation...

Do you mean a function called "filter" should actually apply a filter? For the moment, it would be applied manually by the user.

Then I guess `get_wfs_fir_prefilter` might be a better name? @mgeier : Could you point me to a better way to convolve N (or 1) signals with N (or 1) filters?...

> Since the filter is specific to 2.5-dimensional synthesis I would expect 25D in the function name. @spors : The docs use the term "pre-equalization filter" also for the 6dB...

Then what about `wfs_prefilter_fir` or `wfs_fir_prefilter_coefficients`? We can use wrappers if dimensionality should be part of the function name. Since this only about filter coefficients, no assumptions about usage are...
