Often loose geometry, ie after making some changes find that only get blank screens.
switch to line mode with –golight –line
vary near, far, yfov
check scaled mode
g4daeview.py -t +0 –eye “2,2,2”
To see the lower parts of the geometry with:
g4daeview.py -g 3153:12230 -t +5000 --eye=0,0,10
Have to increase near to 1.01 from initial 0.1. Why is near doing that ?

Need crazy small near in many situations, why? a scaling problem still:
g4daeview.py -g 3153:12230 -t "+0" --nearclip 1e-6,1e6
g4daeview.py -g 3153:12230 -t "" --nearclip 1e-6,1e6
A reasonable near of 10mm gives a blank screen:
g4daeview.py -g 3153:12230 -t "" --nearclip 1e-6,1e6 --near 10
What near is needed for geometry to show up:
g4daeview.py -g 3153:12230 -t "" --nearclip 1e-6,1e6 --near .00029 # extent 8094.19 8 meters
g4daeview.py -g 3153:12230 -t 5000 --nearclip 1e-6,1e6 --near 0.46 # extent 98.14
Removed some scaling, now a more reasonble near of 0.1mm can show large scale and small scale:
g4daeview.py -g 3153:12230 -t "" --nearclip 1e-6,1e6 --near 0.1
Currently working:
g4daeview.py -g 3153:12230 -t "" --nearclip 1e-6,1e6 --near 0.2 --flight 100
Moving scaling into MODELVIEW enables light control:
g4daeview.py -g 3153:12230 -t "" --nearclip 1e-6,1e6 --near 0.2 --flight 1e-6 --eye 2,2,0
After wrapping the unproject calls in matrix push/pop get some coordinates that look like world ones:

Targetting different volumes or all volumes is a quick way to switch between scenarios:
udp.py "-t +500"
udp.py "-t +600"
udp.py "-t +3"
udp.py "-t +2"
udp.py "-t +1"
udp.py "-t +0" # first volume
udp.py "-t """ # all volumes
udp.py "-t -1" # last volume
udp.py "-t -10"
g4daeview.py
g4daeview.py -t ""
g4daeview.py -t "" --nolight --line
g4daeview.py -t +0
g4daeview.py -t +0 --nolight --line
g4daeview.py -t +1000 --nolight --line
View targetting a single small piece of geometry (eg a PMT) within context of many other such pieces of geometry all within containing geometry (eg the AD)
g4daeview.py -g 3153:6000 -t 5000
g4daeview.py -g 3153:6000 -t 5000 --nolight --line # linemode
g4daeview.py -g 3153:6000 -t ""
g4daeview.py -g 3153:6000 -t 3153 --nolight --line
In glumpy original scaled geometry mode the lighting is acceptable with false directional RGB and white background:
g4daeview.py -g 5000:6000
g4daeview.py -g 5000:6000 --lights="rgb" --rlight="-1,1,1" --glight="1,1,1" --blight="0,-1,1" --xyz=0,0,3 # the original defaults, giving same appearance
g4daeview.py -g 5000:6000 --lights="rgb" --rlight="-1,1,-5" --glight="1,1,-5" --blight="0,-1,-5" --xyz=0,0,-3 # white screen, due to position
g4daeview.py -g 5000:6000 --lights="rgb" --rlight="-1,1,-1" --glight="1,1,-1" --blight="0,-1,-1" # flipping z does not mess up just makes a bit dimmer
Reproducing that lighting with world coordinate geometry is being problematic.
