[osg-users] Compute Intersections with GL_POINT drawable

Hello, I am trying to do some hit tests on a geode that only has one drawable of a GL_POINT. It seems my hit test only picks up the very center of the point, no matter how large I draw the point. Could I get some guidance on how to pick the object using the actual size? Here is the picking cod

Re: [osg-users] Deprecated osgViewer::computIntersections

Hi, I'm not sure of the details of your problem, but I recently had a problem with intersections as well. The epsilon value was changed in LineSegmentIntersector.cpp line 410. I changed back to 1e-4 from 1e-13 and it solved my problems. Cheers, Jason -- Read this topic online h

Re: [osg-users] Deprecated osgViewer::computIntersections

Hi, That is the exact build that changed things up. Revision 13710 fixes the uninitialized epsilon, but revision 13753 changed things up again. Cheers, Jason -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=56671#56671

[osg-users] Incorrect rendering when modifying camera

Hello, I am new to OSG and having trouble with modifying the camera. I have added my own event handler to process keyboard inputs to change the camera view. This handler holds references to 5 camera manipulators, and upon a KEYDOWN, it switches to the correct camera manipulator as such: Code:

Re: [osg-users] osgWidget Frame borders

Thank you for your help. Modifying the textures to use CLAMP_TO_EDGE has a positive effect, but does not fix the problem entirely. See attached image. The dark pixels seem to come from some other blending going on... If I switch the theme I use to a full white 66x66 image, the lines do not show
