handle scenes with multiple views with elements that need coordinating on a per view basis.
Added beginings of new osgText::FadeText class (not functionality yet).
"I've made some changes to osg which I think make it easier to control
the render order of CameraNode's. Instead of using the built-in orders
(PRE_RENDER, POST_RENDER, NESTED_RENDER), you can specify an integer
order. Values less than zero are pre rendered in order. Values greater
than zero are post rendered in order. And a value of 0 is equivalent
to NESTED_RENDER.
The changes should be fully backward compatible. Also, I changed the
RenderStageList type from a vector to a list because I needed to be
able to insert values anywhere in the list.
The reason I made these changes was because I wanted to be able to set
the render order of a CameraNode at runtime without having to reorder
it in the scenegraph."
and later in the final submission message (relating to what has been finally been merged) :
"I've rethought my implementation and came up with something a little
better. The setRenderOrder will continue to take an enum, but will
have an optional orderNum parameter which can be both positive and
negative. I think this method is more intuitive and flexible."
"I was experiencing hard crashes of my application when using PBO's on
machines that don't support PBO's. I think osg incorrectly checks if
PBO's are supported.
I added a new method to the BufferObject::Extensions class which
returns if the "GL_ARB_pixel_buffer_object" string is supported. This
fixes the problem on my end. Machines without PBO support will
continue to work and machines with PBO support will still be able to
use it."
think it can be simplified quite a bit. The old code includes
<cmath> for pre-10.2 and anything using something other than g++ 4
and then uses std::isnan. For the most current version, it leaves
out cmath and uses isnan(). std::isnan and cmath work for the
current version, so I just made it include cmath if __APPLE__ is
defined and removed the ifdef between versions of OS X for isnan
related things.
This way the code is all the same, and it's not fragile to someone
including <cmath> prior to including osg/Math."
in incorrect texture assignment. Solution was to a compareTextureObjects() test to the Texture*::compare(..) method that
the osgUtil::Optimizer::StateSetVisitor uses to determine uniqueness.
setFactorAndUnitMultipliersUsingBestGuessForDriver() static methods to
osg::PolygonOffset to help implement workarounds for lack of portablity of
settings between different hardware.
make it consistent with the constructor and prevent the
BlendFuncSeparate path being called. This patch fixed the artifact
with the osgpointsprite demo on ATI cards reported by Mike Weiblen."
"Attached is some fixes for Image::readImageFromCurrentTexture. It was
failing when used with a new Image object (some of the fields were
not set before they were used, and some were set to the wrong values).
A new optional parameter was added to give the desired data type, which
defaults to GL_UNSIGNED_BYTE, so programs should only need a recompile
to work properly."
