textures. Near the top of the function that implements texture
subloading, osg::Texture::applyTexImage2D_subload(), the local variable
compressed_image examines the _image's_ pixel format to see if it is
compressed. However, further on, in calls to getCompressedSize() the
_texture's_ pixel format is used. In my application's Texture2D class,
I use osg::Texture::USE_ARB_COMPRESSION to
osg::Texture2D::setInternalFormatMode(), which causes the internal format
to become one of the generic ARB_COMPRESSED types, which do not have a
specific size. Thus the recent warning message added to
osg::Texture::getCompressedSize() is triggered. The correct behavior is
to use the format mode from the Image class instead of the Texture class
within the subload implementation, and then the size is calculated
correctly."
based on the internal format. There is similar code in the Texture class
but it does not account for the ARB types. I modified the Texture class
implementation to show a warning when an incomplete internal format is
used to calculate the image size."
_TYPES_H_. types.h in the directx plugin defines the same include
guard. I've renamed the guard name in this file to _DX_TYPES_H_. Now
the plugin compile in mingw too."
"Previously, the new OpenFlight plugin only allowed ext ref models to use
their own palettes. With this change, parent models can override child model
palettes with the parent palettes.
These changes are made against very current CVS (just updated about 1/2 hour
ago, eliminated conflicts, and retested before this posting).
To regurgitate what I did:
A new class, ParentPools (public osg::Referenced), is created when an ext
ref record is parsed, and it is populated with any parent model pools that
should override the child model pools (according to bits in the ext ref
record). The ParentPools object is then set as UserData on the ProxyNode
corresponding to the ext ref.
When the ReadExternalsVisitor hits the ProxyNode, it takes its UserData and
sets it as UserData in the Options parameter to the osgDB::ReadNode call,
which then read the ext ref model. In the course of parsing the Options
string, ReaderWriterFLT also looks at the Options UserData and sets the
parent pools in the Document class accordingly.
When palette records are encountered while loading a file, they are ignored
if the corresponding pool was set by the parent.
Thanks to Brede for consulting with me on the implementation.

"attached you'll find some modifications to Producer, osgGA and
osgProducer to enable Mac OS X support for
+ scrollwheels,
+ mightymouse-srollballs
+ new tracking-pads with scroll feature
+ tablet-support (pressure, proximity and pointertype) (Wacom only tested)
I think there was a bug in the windows-implementation of scroll-wheel
support (wrong order of ScrollingMotion-enum, casting problem) which is
fixed now.
The scrollwheel-code is a bit klunky across platforms, some devices on
OS X can report an absolute delta in pixel-coordinates not only the
direction, so for now there is scrollingMotion (which describes the
direction) and scrolldeltax and scrolldeltay. I decided to leave the
scrollingmotion-stuff to not break old code relying on this."
that users can assign to it without it being overriden. If none is
assigned externally it now uses a StateSet associated wit the Font assigned
to the Text.
"The attached file corrects two small typos in MultiSwitch.cpp. The
local "values" reference and the "_values" member attribute are of
different types but both are vectors so the size() operator happily
compiles. A renaming of _values to _masks or similar may be a more
future proof solution but the submission only removes the underscore
in two places.
The switch_1701.flt model part of the Creator gallery revealed this bug."
through the osgDB::readImageFile and osgDB::writeImageFile functions.
This is useful for storing compressed textures on disk for rapid playback
for animations."
From Robert Osfield, remapped Paul Martz's changes to Pools.h and PaletteRecords.cpp w.r.t texturePatternIndex being a in16, and converted a char* string to a std::string.
