Hi, I'm trying to set up viewer for picking using osgpick as a base but I've run into a problem. What I've done is to put the relevant code from osgpick.cpp into code and header files which I then worked into my main program.
I expected that this would just have the effect of displaying an HUD on each of my cameras as well as vertex information (like in osgpick), allowing me then to modify the code and get the functionality I need. However, this resulted in my program crashing. After some debugging, I found out that specifically, whenever I call the line: _viewer->computeIntersections(ea.getX(),ea.getY(),hlist()) the program crashes when it exits the function it was called in. I'm using VC++7, and Visual Studio gives me the following errors upon exiting the function (specifically, PickHandler::pick(const osgGA::GUIEventAdapter &ea)): Debug Assertion Failures: Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse) Expression: _CrtIsValidHeapPointer(pUserData) As well as various unhandled exceptions. I've been using two cameras on my renderSurface and the renderSurface comes up as a borderless window. I've set up the PickHandler to perform a pick upon RELEASE rather than FRAME, so I know that the HUD displays correctly on both cameras and that the PickHandler is functioning properly (if I don't call computeIntersections). I don't know what I've been doing wrong, since the code compiles without errors and I'm fairly certain I'm not referencing anything that's been deleted. Any help?
