Hello,
I'm using VisAD library to visualize a large data sets of mass
spectrometry data in 3D.
I would like to resample the visible part of the data set according
to the current zoom (scale), to get a primitive "level of detail"
support.
I have added a listener for the projection control, so I know when
the scale changes and using MouseBehaviorJ3D.unmake_matrix() I can
get the current scale, rotation and translation values.
But I don't know how to determine the subset of the domain (X/Y
axes), which is currently visible.
Is there any simple way how to do it?
Thanks!
Best regards,
Tomas
