We can reduce the on-disk plane footprint.
I did a quick test compressing f-14b/Models/common2.rgb (texture atlas with
fuselage skin, it seems):
baseline common2.rgb: 792k
png common2.png: 295k (irfanview, best png compression, keep transparent
color ON)
ziped common2.zip: 375k (winrar .rgb, best zip compression)
rared common2.rar: 353k (winrar .rgb, best rar compression)
So there seems to be a case for converting all .rgb to .png. It should
result in a smaller distribution and
a smaller disk footprint (possibly quicker loading 1st time loading). It is
my naive understanding that the
references to .rgb should only be in .xml and .ac files.
A quick shell script could find all .rgb convert them to .png, do a search
replace on .xml and .ac files and
then commit to cvs.
Also i looked into a .AC file to confirm they are text and a /bin/sed
search replace is possible.
My 1 sample size research file f-14b.ac is 2485k uncompressed, 337k
compressed as rar
(winrar, best rar compression). I would even expect gzip to achieve a better
compression ratio.
Again, it should be possible to compress all .ac, either as a pre-pass
on installer generation or to commit it to cvs. The OSG AC loader may need
patching to load .gz files, I ignore if
the osg loader can do the gz streaming itself on all supported file types.
greetings,
yon
