Markus,
I have gotten around to a few more updates to NVIZ that I thought I
would pass along for testing / checking.I have included the accelerated surface drawing routines (gsd_surf.c)
for you to try out. I do not think it is quite right, but some more
testing would be good. The routine is now embedded in both floating
point and integer based maps. When testing you need to look for pieces
of the map that are not getting drawn. This will occur at the edges of
the map.
It looks pretty good and quite fast if you zoom into a map portion.
Up to now I haven't seen any undrawn areas.
I have updated another piece of the key frame mask. The field of view
(FOV) and twist variables are now saved and read from the key frame
animator. In other words you can chenge these parameters from key frame
to key frame. The only remaining piece of the key mask that is not read
and written is the cutting plane info.
The twist ruler is nice and helpful!
The key frame someone with experience should test (I can bounce the
mail from Bob to you, dear tester, then).
Because I added the twist support to the Key Mask I thought it would be
helpful to add an interface for twist. There is now a slider underneath
perspective for adjusting twist. This is a simple adjustment from -180
to +180. The display panel seems to be getting a little crowded. Any
suggestions for an improved position interface? I was also thinking that
a 3D view style panel might be helpful. Here the user could manually (or
from display) set view paramters (like open 3D view) for a specific
view. Most of the commands are already there to implement this.
Well what do the others think? Helena, Jaro?
I have also attached the program (d.nviz) I mentioned a while back for
interactively creating a fly-though script for nviz. I have cleaned it
up a little bit. If you think it has potential I can throw together a
man page for it.
I tried to use it, it is writing a script file (the stdout does not work,
though. It generates a file '-' only instead of writing to stdout).
Further volunteers to test the nice NVIZ improvements?
Thanks
Markus
