creating subclasses of osg::Array that referenced data
stored an application's internal data structures. I took
a stab at implementing that and ran into a couple of
downcasts in Geometry.cpp. Enclosed is my take at fixing
those along with a simple example of how to do this."
1. DAE object no longer held onto by plugin.
2. Filename to URI conversion now handled internally by plugin.
2. User can supply an external DAE object for use by the plugin.
3. User can supply a std:string object for the plugin to return the URI of
the document just processed.
4. User can supply a std::string to receive the unit name information from
the document just read in. (e.g. meters, inches, etc.)
5. User can supply a float to receive the metric conversion factor from the
document just read in.
6. User can supply an enum to receive the up axis orientation information
from the document just read in.
7. Material transparency can be both read and written.
8. User can supply an experimental GoogleMode option on output. The plugin
will try to emulate the way Sketchup specifies transparency (i.e. the
inverse of what it should be!). I am still struggling to get GE to
understand transparency, anyone know what it expects?
9. Rudimentary support for Collada effect parameters (newparam, setparam,
param) on input. Basic nVidia FX Composer dae documents can now be read.

in the DatabasePager. The practical effects of these are to greatly reduce startup time
and the time to load an individual scenery tile in FlightGear.
- From my log message:
Minimize the number of StateSets and drawables that are compiled by checking
if they have already been compiled or will be elminated by the
SharedStateManager.
Move the sorting of the dataToCompile queue out of compileGLObjects
into the man pager run function.
Change the SharedStateManager to use maps instead of vectors."
Previously the complete StateSet was cleared, even the non clipping releted
state attributes and modes in this stateset on a call to
setLocalSetateSetModes.
With this change only those modes/attributes are changed that need to be
changed. That is, if a clip plane is removed from the ClipNode, only this
assiciated mode is removed from the state set, instead of throwing away the
whole state set.
In this way we have less surprising results if the state set of a clip node is
used for more state than just the clip state.

file. I have altered those comments so they now contain valid information for
the BoxPlacer class and the doxygen generated documentation is correct.

fullscreen mode and back between views. (To activate, double click on
the view to toggle.) It demonstrates/uses the new one-liner fullscreen
method introduced in Leopard. Code will still compile and run in
pre-Leopard (thanks to Obj-C dynamic/late binding), but code path is
treated as a no-op in those cases."
CullVisitor/SceneView:
*Feature: This version supports multiple clearnodes in the graph, one per renderstage.
Text:
*Feature: Performance Enhancement when calling SetBackdropColor
Material:
*Fix: OpenGL calls are now made according to the OpenGL Standard

- Material class contained both 'shininess' and 'Ns' member variables
- 'Ns' and 'Ni' are initialized to 0 ('Ni' is unused at the moment)
- only 'Ns' was read from .mtl file but 'shininess' was used for osg::Material
- 'illum' was read from .mtl file but never used; it is now used as follows
-- illum==0 -> no osg::Material created/attached therefore no lighting
-- illum==1 -> osg::Material specular is set to black
-- illum==2 (default) -> specular read from .mtl file is used
- 'map_Kd' and 'map_Ks' may contain additional arguments (e.g. '-s 1 1 1'),
these are now skipped over and the texture filename is properly extracted
