Parallel Projection in 3D Viewer

[JPW]

When setting the projection (from the default Perspective Projection) to Parallel Projection, the view of the 3D object appears to be greatly zoomed in and is unable to zoom out. Is this a known issue?

I have also been using the 3D Viewer API to make a Java application, but I am unable to find any methods for setting the view to Parallel Projection.


Thanks for any help

Parallel projection is not supported in the 3D Viewer at the moment.

In that case, does anyone know of another plugin with similar functionality to 3D Viewer?
I want to render a 3D object (in Parallel Projection), rotate it to specified angles and take snapshots of it.

Thanks

You might want to try the alternative 3D Viewer for Fiji called VisAD. It
is part of the LOCI plugins for Fiji:

        http://loci.wisc.edu/software/fiji-plugins

Of course, we will try to fix the bug in the 3dD Viewer, but it is alwayss
good to have alternatives, right?

Ciao,
Johannes

To add to what Johannes said: the plugin he is talking about is here:

   http://loci.wisc.edu/software/visbio-fiji-plugins

It is the beginnings of an attempt to bring the functionality of VisBio (
http://loci.wisc.edu/software/visbio, which uses the VisAD visualization
library) into ImageJ. Right now the only functionality is a fairly
specialized parallel projection stack visualizer called VisBio Ortho Stack.

If you want to do parallel projections of 3D volumes, you could try the
full VisBio application, but please note that we are not actively
supporting it right now. Rather, the goal is to eventually bring all of its
functionality into ImageJ2 as plugins.

Regards,
Curtis
