parameter in osg::Image. To support this Image::setData(..) now has a new optional rowLength parameter which
defaults to 0, which provides the original behaviour, Image::setRowLength(int) and int Image::getRowLength() are also provided.
With the introduction of RowLength support in osg::Image it is now possible to create a sub image where
the t size of the image are smaller than the row length, useful for when you have a large image on the CPU
and which to use a small portion of it on the GPU. However, when these sub images are created the data
within the image is no longer contiguous so data access can no longer assume that all the data is in
one block. The new method Image::isDataContiguous() enables the user to check whether the data is contiguous,
and if not one can either access the data row by row using Image::data(column,row,image) accessor, or use the
new Image::DataIterator for stepping through each block on memory assocatied with the image.
To support the possibility of non contiguous osg::Image usage of image objects has had to be updated to
check DataContiguous and handle the case or use access via the DataIerator or by row by row. To achieve
this a relatively large number of files has had to be modified, in particular the texture classes and
image plugins that doing writing.
I don’t have access to an OSX or Linux dev machine to make the changes required to the quick time plugin. This plugin will just default to returning 0."
Motivation ;
When using PagedLODs, you don't always know the real size of loaded children,
If it occurs that they are out of predefined bounds, picking on the parts that are out of bound will fail
They also can be culled out too soon.
The problem often occurs with long object (roads).
I've modified LOD and ProxyNode to include this option."
and later email:
"Attached the UNION_OF_BOUNDING_SPHERE_AND_USER_DEFINED version
There are impacts on some serializers (dae, osgWrapper).
I haven't modified deprecated osg, since it's deprecated"
So with the 3.0 api change we propose the following change:
- put OSG_EXPORT on the QueryGeometry class so that we get access to the getNumPixels method.
- Create a function called getQueryGeometry that returns a casted _queryGeode->getDrawable(). Or a function called getQueryGeode that returns _queryGeode."
Added COMPUTE_NEAR_FAR_USING_PRIMITIVES option that provides the original functionality where only the near plane
is computed in a fine grained way, with the far plane being computed simply from bound volumes.
with a osg::DefaultUserDataContainer subclassed from this. The user object access methods have now all
been moved from osg::Object into the UserDataContainer class, except for the set/getUserData() methods
that are left in osg::Object for backwards compatibility, and the description list access methods have
been moved back into osg::Node.
main UserObject access methods are now all def
Refactored original UserData and Descriptions strings to be managed alongside the new user object suppport within
a single osg::Object::UserDataContainer.

CID 11447: Unchecked dynamic_cast (FORWARD_NULL)
Dynamic cast to pointer "dynamic_cast <struct osg::NodeCallback *>(nc->clone(this))" can return null.
Assigning null: "first" = "dynamic_cast <struct osg::NodeCallback *>(nc->clone(this))".
The clone() implementation is written using macro's so that it always returns the type of Object
being cloned so it's normally safe to assume that a dynamic_cast<> will always return a valid pointer as long
as the new T that involves creates a valid object. However, if the class being cloned doesn't correctly
implement the clone() method then their potential for the dynamic_cast to fail and will return a NULL and will
result in a memory leak of the object of paraent class that the clone would have defaulted to.
I've tightened up the CopyOp.cpp code to check the return type and added better handling of the clone in the
osg::clone() methods so thay don't have any potential mememory leaks and report warnings to OSG_WARN when
problems are encountered. It may be more apporpriate to throw an exception so will need to ponder this
issue further.
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."
I also fixed the vsync implementation introduced with rev.11357 that was crashing with the Windows Error #170. So I removed your temporary /* */ around the vsync condition..."
