sciView <> BDV transform sync

[moreApi]

resp: Jan

Notes so far:

• sciview VolumeTimeSeriesDemo
• affineTransform3D
• in run funktion gucken was bdv einem mit auto complete
  • viewer pannel. add transform listener
• https://docs.google.com/presentation/d/1-3qUbKlIRh07mJk7MiXfNTNP-5v2uFvQUmoIlrpJjUg/edit#slide=id.gc9ec5609c0_0_45
• "so i have a mental model where we see a 2d plane/thin box in the volume that corresponds to the current bdv window it scales based on the bdv zoom and rotates/translates as the bdv window is changed and we can move it in sciview as well of course we should be able to hide it, as well, but we get that for free anyway"
• "i see it as a Node with a box representation (w/h/1 voxel deep) that syncs its translation/rotation/scale with a BDV window"
• "it could start as a demo, but ideally it would be a Command that associates this node to a volume and creates a BDV window when it is created"
• the way back? https://github.com/tpietzsch/jogl-minimal/blob/3657fcbeb4dd123f27118b730956d51ea6b5b660/src/main/java/tpietzsch/example2/VolumeViewerPanel.java#L980-L981 https://github.com/tpietzsch/jogl-minimal/blob/3657fcbeb4dd123f27118b730956d51ea6b5b660/src/main/java/tpietzsch/util/MatrixMath.java#L37
• "if you make a camera at 0:x,0:y,-1:z that looks at 0:x,0:y,0:z, then you get the BDV/ ImgLib2/ image processing friendly right handed coordinate system with x pointing right, y pointing down, z pointing into the screen"
• "@moreApi rotate by 180 degree about the X axis (which corresponds to inverting Y and Z) (BDV also uses right-handed system, with Z pointing "into the screen")"
• sciView: x points to the right, y upwards, negative z into the screen
• inverse does strange stuff to translate part

@moreApi @skalarproduktraum what is the status on this?

[moreApi]

If I remember correctly, @skalarproduktraum and I were not able to figure out how BDV builds its model?view matrix and gave up at some point.

Maybe this is something to sync up with @tpietzsch about. @moreApi and @skalarproduktraum are either of you going to the Brno hackathon in October?
