Hi all,
i'm trying to implement PickHandler in my application with osg 1.2.
Following example osg::pick i have written the following lines of
code:
bool PickHandler::pick (const double x, const double y,
osgProducer::Viewer* viewer)
{
std::vector<osgUtil::Hit> hlist;
if ( viewer->computeIntersections(x, y, hlist) )
{
//Here i handle the information recovered from computeIntersections()
hlist.clear();
}
return true;
}
Im working under Windows: the resulting application works well if i
compile it in release mode but when use in debug mode it give me the
following error on instruction hlist.clear(). If i don't call this
instruction it give me the same error at the return (because the
application try to empty Heap).
Debug Assertion Failed
File:dbddel.cpp
Line:52
Exception: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse).
I have tried to comment the code containing computeIntersection and
all works well. It seems that computeIntersections function do
something on hlist, avoiding to empty memory.
How can i resolve this problem? Does exist another functionto to have
the same behaviour? How can i try to resolve this problem?
Thanke in advance
Francesco Argese
