shadowedScene-setCastsShadowTraversalMask(CastsShadowTraversalMask);
osg::ref_ptrosgShadow::ShadowMap sm = new osgShadow::ShadowMap;
shadowedScene-setShadowTechnique(sm.get());
}
I can't see anymore my widgets.
I make my widgets with
Code:
camera = windowManager-createParentOrthoCamera();
In windowManager I add box, label, widget etc.
and then
Code:
shadowedScene-addChild(camera);
Why?

[osg-users] Question about osgAnimation Bezier curves
Hi, I try to understand and modify osg example osganimationmakepath. I want to realize a simple path like the figure. I've the keyframes keys-push_back(osgAnimation::Vec3CubicBezierKeyframe(0, osgAnimation::Vec3CubicBezier(v[0],v[1],v[1]) )); keys-push_back(osgAnimation::Vec3CubicBezierKeyframe(5, osgAnimation::Vec3CubicBezier(v[2],v[1],v[1]) )); keys-push_back(osgAnimation::Vec3CubicBezierKeyframe(10, osgAnimation::Vec3CubicBezier(v[3]) )); with: v[0] = osg::Vec3( 0, 0, 0); v[1] = osg::Vec3(0, 0, 20); v[2] = osg::Vec3(20, 0, 20); v[3] = osg::Vec3(40, 0, 20); where v[0] = P0 v[2] = P1 v[3] = P3 and v[1] is the control point P3 The curve part works fine, but when the object arrives on point P1 it doesn't move to P2 but it come back to P1 and then goes to P2.

Re: [osg-users] Strange error only in debug mode
Hi, that's not a problem, I had the same also before insert the removecallback. My program use the reactivision tracking system (with TUIO server) and implements an augmented reality software. In osg I receive position of marker taken by reactivision and for every position I call an update callback for update object's position. Then that's impossible that I call an update callback over an object that's not exists. I never destroy objects. Alberto Luaces wrote: daniele argiolas writes: Thank you.

Hi, I've a program with some updateCallbacks of some objects.

Unhandled exception at 0x102b6ef5 (osg65-osgd.dll) in ARGAME.exe: 0xC005: Access violation reading location 0xfeeefeee. And then it breaks my program into void NodeCallback::traverse(Node* node,NodeVisitor* nv) function. I tried different ways but only in Debug mode it generates this error, sometimes immediatly, sometimes after some minutes. Do you know why it is generated only in debug mode? And what error is it?
