I stumbled on your own AMB-Plugins. :)
They seem to do pretty much what I need. Mono->B-Format panner provides
only angle controls.
yes. panning is only concerned with angle of incidence, whether in
ambisonics, VBAP, or pair-wise stereo.
So from what I can understand, if I apply doppler
effect, distance
attenuation and other pre-process filters to a mono input and then push
it through the panner plugin I get fairly correct representation of
sound in 3D space. Right?
depending on what you mean by "fairly correct", "representation", and
"3D space" :-D
doppler would come into play only if you change the distance of the
sound, not when you move it on the sphere, as the distance remains constant.
when you hand-craft distance cues, you should not expect wonders for
sounds originating inside your sphere of speakers. travelling through
the center quickly can be made to work, though.
I failed to find anything discussing mixing in AMB.
Can I just sum the
channels of all sounds, like I would do it to any
"direct-speaker-to-channel" formats?
yes. that's a fundamental property of all linear systems, and
independent of the signal representation.
i've written a little howto for ambi mixing in ardour a while ago, maybe
you'll find it useful:

for lac2010, i tried to find out how ambisonic mixing can be applied to
a pop production:
