Hi Ale,
Thanks for the updating test program, this illustrates a separate bug
in the KdTree copy constructor. I have added missing copying of the

Re: [osg-users] RayIntersector with KdTree causes a crash
Hi Robert, thanks for the update. The issue with ShapeDrawable take us to the wrong way. So at the end we find the cause of the problem is different. I will describe it again: 1 - Take a geode (e.g. we loaded "cow.osg") and build a kdtree 2 - Make a clone with DEEP_COPY_ALL 3 - Applying LineSegmentIntersection to the clone we get the crash If we clone with SHALLOW_COPY it works fine Attached is the modified osgPick example that reproduces the crash. You just need to set the correct path to the file to be loaded and specify the --relative-camera-scene option as before Here is an extract of the code. If you use a SHALLOW_COPY instead of DEEP_COPY_ALL it does not crash. [code] osg::MatrixTransform* xform = new osg::MatrixTransform(); osg::MatrixTransform* xform2 = new osg::MatrixTransform(osg::Matrix::translate(10.0,0.0,0.)); osg::ref_ptr kdtreeBuilder = NULL; kdtreeBuilder = osgDB::Registry::instance()->getKdTreeBuilder()->clone(); xform->addChild(cow); // xform->accept(*kdtreeBuilder); osg::Object * cow2 = cow->clone(osg::CopyOp::DEEP_COPY_ALL); xform2->addChild(cow2->asNode()); group->addChild(xform); group->addChild(xform2); [\code] Cheers, Ale -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=74652#74652 Attachments: http://forum.openscenegraph.org//files/osgpick_not_working_865.cpp ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
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

Re: [osg-users] RayIntersector with KdTree causes a crash
Hi Ale, I built with release. I will try with a debug build. A change in behaviour between release a debug would suggest an unintialized variable. Could you provide the stack trace.

Re: [osg-users] RayIntersector with KdTree causes a crash
Hi Robert, thanks for the update. Have you built in release? We are seeing now that the release version has the behaviour you described (that is also strange becouse I expect to see something… if you do not build the KdTree in the code you can see the sphere). The debug version crashes (the assert Windows says there is a call to front() of an empty vector). It is correct you run with the --relative-camera-scene command line option. If needed I can send you the Windows binaries of the example.

Re: [osg-users] RayIntersector with KdTree causes a crash
Hi Ale, I have now built and run your test and it works fine for me. I have run with the --relative-camera-scene command line option and I don't see any cube or sphere, but I do see reports of hits. This is testing with the 3.6 branch under Kubuntu 18.04. At this point I don't have anything to go any further. Ideally I need a test case that I can reproduce a problem, and if this isn't straight forward then I need stack traces of what is happening on your system.

Thanks for the test example. I don't have time right now to look into it, but once I've achieved a couple of milestones on my Vulkan work I'll return to clear up outstanding OSG bugs.

Hi Robert, my colleague reproduced the crash by modifying the osgPick example. He created a sphere with a negative scaling transformation, build the kdtree and attached to the osgPick scene.

Re: [osg-users] RayIntersector with KdTree causes a crash
Hi Ale, The KdTree was refactored in 3.6.x to add support for points and lines and PolytopeIntersector. While there has been lots of internal changes in it, it of course shouldn't crash. At this point in time I don't have any idea where the issue stems from. Could you create a small example that reproduces the crash, I or others can then step through what is happening and work out a fix. Given this regression it looks like we'll have to make a 3.6.3 sooner rather than later, but not before we fix the crash... Cheers, Robert.

Here is the call stack when crashed: > > > osg157-osgUtild.dll!std::vector > int,std::allocator >::operator[](const unsigned __int64 _Pos) > > Line 1818 C++ > > osg157-osgUtild.dll!osg::KdTree::intersect > > > >(osg::TemplatePrimitiveFunctor > > & functor, const osg::KdTree::KdNode & node) Line 160 C++ > > osg157-osgUtild.dll!osg::KdTree::intersect > > > >(osg::TemplatePrimitiveFunctor > > & functor, const osg::KdTree::KdNode & node) Line 176 C++ > > osg157-osgUtild.dll!osg::KdTree::intersect > > > >(osg::TemplatePrimitiveFunctor > > & functor, const osg::KdTree::KdNode & node) Line 176 C++ > > osg157-osgUtild.dll!osgUtil::LineSegmentIntersector::intersect(osgUtil::IntersectionVisitor > & iv, osg::Drawable * drawable, const osg::Vec3d & s, const osg::Vec3d & e) > Line 540 C++ > > osg157-osgUtild.dll!osgUtil::RayIntersector::intersect(osgUtil::IntersectionVisitor > & iv, osg::Drawable * drawable) Line 122 C++ > > osg157-osgUtild.dll!osgUtil::IntersectionVisitor::intersect(osg::Drawable * > drawable) Line 282 C++ > > osg157-osgUtild.dll!osgUtil::IntersectionVisitor::apply(osg::Geode & geode) > Line 240 C++ >osg157-osgd.dll!osg::Geode::accept(osg::NodeVisitor & nv) Line > 37 C++ >osg157-osgd.dll!osg::Group::traverse(osg::NodeVisitor & nv) > Line 63 C++ > > osg157-osgFXd.dll!osgFX::Effect::inherited_traverse(osg::NodeVisitor & nv) > Line 213 C++ >osg157-osgFXd.dll!osgFX::Effect::traverse(osg::NodeVisitor & > nv) Line 51 C++ >osg157-osgd.dll!osg::NodeVisitor::traverse(osg::Node & node) > Line 278C++ > > osg157-osgUtild.dll!osgUtil::IntersectionVisitor::apply(osg::Group & group) > Line 221 C++ >osg157-osgFXd.dll!osgFX::Outline::accept(osg::NodeVisitor & > nv) Line 54 C++ >osg157-osgd.dll!osg::Group::traverse(osg::NodeVisitor & nv) > Line 63 C++ >osg157-osgd.dll!osg::NodeVisitor::traverse(osg::Node & node) > Line 278C++ > > osg157-osgUtild.dll!osgUtil::IntersectionVisitor::apply(osg::Transform & > transform) Line 417 C++ >osg157-osgd.dll!osg::NodeVisitor::apply(osg::MatrixTransform & > node) Line 158 C++ >osg157-osgd.dll!osg::MatrixTransform::accept(osg::NodeVisitor > & nv) Line 37C++ >osg157-osgd.dll!osg::Group::traverse(osg::NodeVisitor & nv) > Line 63 C++ >osg157-osgd.dll!osg::NodeVisitor::traverse(osg::Node & node) > Line 278C++ > > osg157-osgUtild.dll!osgUtil::IntersectionVisitor::apply(osg::Group & group) > Line 221 C++ >osg157-osgd.dll!osg::Group::accept(osg::NodeVisitor & nv) Line > 38 C++ >osg157-osgd.dll!osg::Group::traverse(osg::NodeVisitor & nv) > Line 63 C++ >osg157-osgd.dll!osg::NodeVisitor::traverse(osg::Node & node) > Line 278C++ > > osg157-osgUtild.dll!osgUtil::IntersectionVisitor::apply(osg::Transform & > transform) Line 417 C++ >osg157-osgd.dll!osg::NodeVisitor::apply(osg::MatrixTransform & > node) Line 158 C++ >osg157-osgd.dll!osg::MatrixTransform::accept(osg::NodeVisitor > & nv) Line 37C++ >osg157-osgd.dll!osg::Group::traverse(osg::NodeVisitor & nv) > Line 63 C++ >osg157-osgd.dll!osg::NodeVisitor::traverse(osg::Node & node) > Line 278C++ > > osg157-osgUtild.dll!osgUtil::IntersectionVisitor::apply(osg::Group & group) > Line 221 C++ >osg157-osgd.dll!osg::Group::accept(osg::NodeVisitor & nv) Line > 38 C++ >osg157-osgd.dll!osg::Group::traverse(osg::NodeVisitor & nv) > Line 63 C++ > > osg157-osgShadowd.dll!osgShadow::ShadowedScene::traverse(osg::NodeVisitor & > nv) Line 69 C++ >osg157-osgd.dll!osg::NodeVisitor::traverse(osg::Node & node) > Line 278C++ > > osg157-osgUtild.dll!osgUtil::IntersectionVisitor::apply(osg::Group & group) > Line 221 C++ > > osg157-osgShadowd.dll!osgShadow::ShadowedScene::accept(osg::NodeVisitor & nv) > Line 36 C++ >
