Subject: navigating in NVIZ - a suggestion

Platform: GNU/Linux/i386
grass obtained from: Mirror of Trento site
grass binary for platform: Compiled from Sources

NVIZ's navigation is usable but what I saw in VTP is perfectly simple and powerfull
when compared. Please take a look:

And try the VTP if you haven't yet :).

Hi,

A collegue has still implemented a similar navigation for NVIZ... I hope it
will be released as soot as possibile. We called it Flythrough navigation.

If you need explications you can directoly ask to Massimo Cuomo: m.cuomo@acsys.it

Indeed, this looks cool. But the navigation doesn't work properly:
1. in basic, the "hold left and right" does the same what "hold middle" button
does, thus panning is not possible
2. in simple mode "hold left and right" doesn't work at all

I don't think this could be related to my particular mouse configuration. I
experience the problems above with two different mice (both 3 button, PS/2) on
two different machines: one Mandrake 10.1, one Ubuntu 5.10. I didn't mess with
my default mouse setup at all, all keys work as xepected in other apps.

Thanks for this new feature. Nice work. If only those two issues could be
fixed it would be perfect.

Best is to contact the author (Massimo Cuomo)...

I CCed Massimo that time (I think), though it's been some time now and no
response from him, so I'm CCing him again.

Massimo,

Can you take a look at this problem?

Best,
Maciek

A note:

I need to look into how the xorg.conf's

Option          "Emulate3Buttons"       "true"

affect this issue (this is the default setting in all Linux distros I ever tried).

So I finally checked it. Yes, this is the culprit. For the flythrough NVIZ
navigation mouse controls to work correctly one needs to set:

Option          "Emulate3Buttons"       "false"

in his X server config to prevent X server from interpretting the mouse
left+right buttons as the middle button. "Emulate3Buttons" "true" is often set
by deafult in various GNU/Linux distros. Is there a way for NVIZ to somehow
ignore this?

No. The only option is to change the NVIZ bindings so that it doesn't
require LMB+RMB to be pressed simultaneously.

Incidentally, this combination is typically impossible with laptops
which use a touchpad instead of a mouse; there's normally a key which
can be pressed to make the touchpad generate RMB events instead of
LMB, but you can't get both simultaneously.
