osgconv --compressed-dxt1 cow.osg cow.ive
due to different handling of the extentions in osg 3.4 and up.
attached is a zip with the files:
OpenSceneGraph\applications\osgconv\osgconv.cpp
This file is valid for svn branch and stable3.4."
git-svn-id: http://svn.openscenegraph.org/osg/OpenSceneGraph/trunk@15124 16af8721-9629-0410-8352-f15c8da7e697
80 columns. I reorganized some of the help strings to make the output of
osgconv --help --all
fit to 80 columns. This avoids difficult to read line breaks added by the
terminal program itself."
First Submission email from Gustav:
"This submission adds a --cache option to osgconv and osgviewer that enables setObjectCacheHint(osgDB::Options::CACHE_ALL); It greatly reduces memory usage when a .osg file has lots of external references with ProxyNode:s that points to the same file.
Options are also added to the osg plugin. The code was already mostly implemented but there was no way to change the options.
includeExternalReferences
writeExternalReferenceFiles
A counter is added to keep track if an external file has already been written down to avoid writing the same file over and over again. If it has already been written once then it is not written again.
The counter is added to the Output class in osgDB.
"
Second Submission email from Gustav:
"This is a continuation to my previous submission.
I noticed that the same problem that I fixed in ProxyNode.cpp for the osg plugin (external files being written over and over again) also existed in the ive plugin. I attached a submission where the ive plugin remembers which external files that have already been written and do not write them again."
Changes to the above done by Robert Osfield,
changed command line parameter to --enable-object-cache
changed set/get methods in osgDB::Output and ive/DataOutputStream.cpp to be s/getExternalFileWritten(const std::string&)
cleaned up set up of osgDB::Options.
" + "Further improvement for conversion to IVE format. Compressed DDS files are written for IVE output when noTexturesInIVEFile option is defined i.e. osgconv --compressed -O noTexturesInIVEFile dir1/input.osg dir2/output.ive will write images into dir2."
The code changes osgconv so that "osgconv --help" displays help info about --formats and --plugins, plus it also displays documentation for --format and --plugin, which were previously missing."
2) complementarily add a "--overallNormal" to replace
per-vert/per-facet normals with an overall. simplifier doesn't work
in certain cases without less complex normals. this gets that done.
3) add env var output with full verbose output so people realize it's
active when the app is run - i see this all the time in training where
people run osgconv, with unintended data transformations due to
osgUtil:;Optimzer, for example"
provides a mechansim for adding in a white colour where none previously
existed. This solves the problem that exists on some databases where
no colour is present, causing the colour to be inherited randomly.

into applications directory. Leaving them in the examples directory
as well, for now.
Made examples optional via the make COMPILE_EXAMPLES=yes option
Added static lib and static plugin build support.
