[osg-users] GL profiles issues on Windows
Hi all, I have some osg-based libraries that are addressing only GL3+ Core profile functionalities, as I need them to work on Mac. Now on Windows, I expected them to work just by compiling osg with the OSG_GL3_AVAILABLE flag. What happens instead is: - if I build osg with GL core profile (no GL 1 and 2, no FFP enabled, ecc...) everything works - if I build osg just adding the OSG_GL3_AVAILABLE flag and launch the application by specifying a GL 3.2 Compatibility profile, I get no errors but nothing shows up Are my expectations correct? Should I check some more compilation / runtime settings to have it working? My setup is: osg 3.6.2 win 10 nvidia GTX card Thank you, Riccardo ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Please test OpenSceneGraph-3.6 branch, to help prep for 3.6.3 release
Hi All, I have checked in fixes/improvements to 3.6 (also applied to master) to address all of the issues that I recall having popped up on osg-users ML/forum since 3.6.2. I have have missed an issue, if so please let me know on this thread. My plan this month is to make a OpenSceneGraph-3.6.3 maintenance release, I am presently only working on a Linux dev system so need the community to test out on other platform combinations and their own applications to make sure that 3.6.3 is solid. https://github.com/openscenegraph/OpenSceneGraph/tree/OpenSceneGraph-3.6 Robert. -- ChangeLog since 3.6.2 Tue, 4 Sep 2018 15:26:30 +0100 Author : Robert Osfield Changed the ShapeDrawable::build() methpd so that it does run when the ShadpwDrawabe is a KdTree.

Re: [osg-users] RayIntersector with KdTree causes a crash
Hi Ale, I have invested the issue further, focusing on why the sphere appears fine when the KdTree isn't build, but disappears when it is. I tracked this issue down to the ShapeDrawable::setShape() being invoked by the KdTreeBuilder that creates a KdTree for a ShapeDrawable then assigns this KdTree to the ShapeDrawable via the Drawable::setShape() method which in turn invokes the ShapeDrawable::build() method that attempts to build a geometry from the KdTree. It's a bit of circular reference - KdTree wasn't ever meant to work with ShapeDrawable, it's only now working because of the change of ShapeDrawable from subclassing from Drawable to subclassing from Geometry. To prevent the unintended rebuild I have disable the ShapeDrawable::build() from doing anything when the shape assigned is a KdTree. https://github.com/openscenegraph/OpenSceneGraph/commit/5f9c6a01704e26e6760cc023e09ab1dcf0da1a15 There is still a bit of mismatch in that KdTree is a special case of a Shape, but still a valid use. Shape's were always intended to be used for intersection testing and physics, but never originally intended to support a ShapeDrawable. The ShapeDrawable was a quick and easy thing to add to help visualize primitive shapes but in hindsight I should never have implemented it as it's misused too much by the community as a serious means for drawing objects. It's not possible to remove ShapeDrawable without breaking lots of user applications so it's still part of the OSG. Please consider it just there for backwards compatibility. The above change is now checked into master and the OpenSceneGraph-3.6 branch. so it will be part of the 3.6.3 release I'll make this month. Testing of these changes would be appreciated.

Re: [osg-users] RayIntersector with KdTree causes a crash
Hi Robert,
I attached the stack trace for the modified osgPick example.
We analyzed the LineSegmentIntersector::intersect code (see below) and we saw
that if we build KDTree AND the transofmation matrix has negative scale then
"geometry->getVertexArray()" returns an empty array and "settings._vertices"
becomes empty.
In debug an assert stops the execution (see stack trace), in release the
execution continue but the geometry is not shown
Code:
void LineSegmentIntersector::intersect(osgUtil::IntersectionVisitor& iv,
osg::Drawable* drawable,
const osg::Vec3d& s, const osg::Vec3d& e)
{
if (reachedLimit()) return;
LineSegmentIntersectorUtils::Settings settings;
settings._lineSegIntersector = this;
settings._iv =
settings._drawable = drawable;
settings._limitOneIntersection = (_intersectionLimit ==
LIMIT_ONE_PER_DRAWABLE || _intersectionLimit == LIMIT_ONE);
osg::Geometry* geometry = drawable->asGeometry();
if (geometry)
{
settings._vertices =
dynamic_cast(geometry->getVertexArray());
}
Cheers,
Ale
