- Support for writing unsigned 16-bit images (GL_UNSIGNED_SHORT)
- Code to parse the options string for the following options:
-- Flag to turn off the compression. The PACKBITS compression type causes issues for me with some programs on Windows (Picasa for example).
-- Options to set the XRESOLUTION and YRESOLUTION tags (DPI) in the TIFF file.
Existing behavior (PACKBITS compression, DPI tags left at default) is preserved if the options string is not set.
"
"I checked your solution and found one missing point which makes it still produce the tif error:
The very first seek_set on the empty stream with zero offset."
"This means that the empty stream is seeked again resulting in the fail bit to be set. Your code does not check this case, furthermore you use t_off instead of std::ostream::streampos for the tellp() calls. In this special case (empty stream) tellp() returns -1 which is cast to 0xFFFFFFFFFF as t_off is unsigned. I suggest this addition to your code (within the switch statement)"
Here is a quick list of the modified files:
Archive - getDirectoryContents() no longer pure virtual
Archive.cpp - default getDirectoryContents() implementation
unzip.cpp - modified to fix a bug where the same file will not load twice in a row
ZipArchive.h / ZipArchive.cpp - extends osgDB::Archive and provides support for random access loading within a .zip file
ReaderWriterZip.cpp - modified to use the ZipArchive class"

Other changes in this sumbission include the added ability to tessellate polygons in Collada reader, with appropriate options.
- No tessellation
- Tessellate as triangle fan (previous behaviour, kept as default for backward-compatibility)
- Full tessellation
I also put auto_ptr<> for RAII of DAE structure (as discussed), and moved reader options in a structure, as for the writer.
Code also make use of osgDB::ExternalFileWriter I submitted, so please merge this submission after the PluginImageWriter one.

Added implementations of these new methods into src/osgPlugins/osga/OSGA_Archive.h src/osgPlugins/osga/OSGA_Archive.cpp
The pvr format which can be used as a wrapper for different compressed and uncompressed formats supports this compression algorithm. The original pvr compression uses the pvrtc format. The handling of pvrtc is already implemented in the pvr plugin. PVR provides wrapper functionality for some formats, e.g. etc or even dxt/dds.
Our target system (gles2) is able to use the etc compression format. With minor changes in the submitted files, there is no need to write a separate plugin. However the original pvr texture compression formats are not supported on our target, which is the reason for this extension.
The changes mainly consist in the definition on new enum values in the classes and headers of ReaderWriterPVR,Image and Texture. I also found some locations where the handling of the original pvr textures was not implemented. These are also part of this submission."

in the model I have tested cot->getParam()->getRef() return 0x0 and make
it crahes inside GetFloat4Param.
I have added a test before calling GetFloat4Param

One can override this value via the sampleDensityWhenMoving="value" property in the volume tag, i.e.
<volume sampleDensityWhenMoving="0.01">CardiacCT</volume>
To switch the feature off set the value to 0, i.e.
<volume sampleDensityWhenMoving="0">CardiacCT</volume>
