Hi,
2008/9/6 Paul Kelly <[EMAIL PROTECTED]>:
Except for one thing: the g.mremove script has dview= rather than
3dview=. The C modules has 3dview=, and both versions of g.mlist use
type=3dview. I'm not sure if there's a reason for this, or if it was
just a typo.
I don't see any reason why to support 3dview type in GRASS7.
Why - is there a replacement for this? (Really sorry I haven't been keeping
up to date with improvements to OGSF and 3-D visualisation functionality.)
Tcl/Tk Nviz will be replaced by wxGUI Nviz extension. All settings
should be stored in the workspace file (gxw).
Nviz never really worked properly with 3dview files. (Bob Covill added some
support at one stage after some nagging by me, but it didn't fully work so
wasn't much use for faithfully recreating a 3d-view.) The really useful
thing about 3dview files IMHO is specifying an exact observer location,
field of view, yaw, pitch and roll angles and recreating the view as would
be seen by an observer at that point. This worked great in the old SG3d
(and in d.3d) and I used it in some research a few years ago. But the
Silicon Graphics machines in my old lab (needed to run SG3d) are long
since scrapped and the ability to faithfully recreate a 3-D view has been
sorely missing from Nviz. Last time I looked the functions to load a 3-D
view file were still there in the OGSF library so I was kind of hopeful
that this could be got working again at some stage.
