Hi Steve,
I am loading up post-processed WRF data and want to use the flythrough
capability.
1. Do I need a plugin or does 2.8u1 already have everything?
2. the pdf user's guide portion on setting up a flythrough is really brief and
I didn't succeed. Are there other sources (written tutorial/webcast) where I
could get spun-up?
3. the import XML file (with points listed) is another way to go, but again, it
was too brief -- I didn't see a format in the user's guide. Where could I find
this?
This is a pretty new facility in the IDV. There is some documentation here:
http://www.unidata.ucar.edu/software/idv/release/nightly/docs/userguide/misc/Flythrough.html
but it doesn't touch on the format that can be externally defined.
The easiest way to create a track is with the IDV Drawing Control. Draw
a polygon and, from its properties dialog you'll see a start flythrough
button, (or by doing control-F for the selected polygon).
You can export the points from the Flythrough dialog File->Export menu.
Its a simple xml format that could then be edited.
You can also manually add a point with the Flythrough dialog Edit->Add
Point. This includes the viewpoint matrix of the 3D view. This kind of
point can also be exported but the matrix format is not readily readable.
