that the terrain is always the Earth planet. I changed the constructor
method to accept the Equator radius and the Polar radius like
parameters. By default, it assumes the Earth radius for the
EllipsoidLocator. I added a setEllipsoidModel method, too.
Now, we are developing some libraries for a GIS applicacion, and our
libraries can visualize terrains of planets like Mars. I think that is
a interesting change."
I added _preDrawCallback member and neccessary access methods plus modified osgUtil RenderStage.cpp to invoke it before all drawInner calls are made. I tried to maintain symmetry with postDrawCallback but you know better where is a proper place for this call ;-)

window.
The win32 implementation is still in its original shape since I have no win32
implementation available.
I have chosen the enum approach for the first cut. That is benefitial since
the user does not need to track creation of mouse cursors for different
windows and displays in presence of multiple viewer windows.
The default set of available mouse shapes is the same set that was available
with glut. That set served many OpenGL applications well, so the hope is that
this is enough.
Even though, that implementation is still extensible:
I have digged out the way SDL defines new mouse cursors and added a still
documented out function prototype in the GraphicsWindow that can be used to
extend the current implemtation for arbitrary mouse shapes. That is not
implemented yet.
I hope that somebody with a win32 test system can catch up that implementation
on win32."
that has greater than unsigned short number of vertexes. An object
called vertexPtrToIndexMap contains vertexes and their indexes. This
std::map object can obviously hold a quantity that is greater than
unsigned short, however osg::DrawElementsUShort objects were being
created to reference these vertexes and their indexes.
osg::DrawElementsUShort can only hold indexes that are 16-bit
quantities.

proposed_patch_2\tessellator.cpp. This solution examines the size of
vertexPtrToIndexMap and selects 1 of 3 possible osg::DrawElements
objects: DrawElementsUByte, DrawElementsUShort, or DrawElementsUInt.
The main drawback of this particular solution is the code duplication.
However, the repair is straightforward."
The major modification concern the LineProjector class in Projector.cpp. The intersection was previously done in window space, I've modified it to compute it in object space."
the specification. With these mods, blink sequences are now created for
flashing light point nodes, either palletized (v.15.8 and later) or
non-palletized (15.7 and earlier). Thanks to Brede for his
implementation of the palletized light point nodes.
There is still work to do on adding the capability to properly handle
light point system nodes, but this does add some capability that did not
previously exist. So, I wanted to at least submit this and I will
hopefully provide the additional capability in the near future.
I've tested the code modifications with Visual Studio 2005. I don't
have the means to test any other operating system, but I would suspect
that there shouldn't be any issue (famous last words). I used the test
files that I uploaded to the users forum to test the changes.
In addition to the added capability, I changed the light point node
radius to the "actualPixelSize" value in the file. Previously, the
radius was set to half the actual pixel size (see
LightPointRecords.cpp). Not sure why this was the case. But, it was
brought to my attention by a co-worker who created the OpenFlight files
and was testing them with different viewers. If there's some history
for setting the radius to half the size, then this change can be
omitted."
implements the LightPointSystem class to allow for the OpenFlight
plug-in to read and handle light point system nodes. The behavior is
very similar to the old plug-in in that a MultiSwitch node is created to
handle the "enabled" flag bit set in the node record. The code also
reverts the changes for the actualPixelSize as mentioned above. And
lastly, the code requires the previously submitted changes for the
plug-in.
As for the other changes, I've tested the code with Visual Studio 2005
and the files that I posted in the users forum.
With all of the submitted changes, the OpenFlight plug-in should now be
capable of loading files with light point system nodes and the use of
palletized light points and non-palletized light points.

accepted file extensions, so that once the plugin was loaded in the
Registry it would grab any image file write request, regardless of the
file extension. This was a particular problem if it was statically loaded."
