I'm attempting to explicitly set the view matrix for a camera in osgViewer. I'm not using viewer->run() so I'm not using the default camera manipulator. Here's the code I'm using:
osg::Matrixf vm;
vm.setRotate(osg::Quat(0.0, osg::Vec3(0.0, 0.0, 1.0),
0.0, osg::Vec3(1.0, 0.0,
0.0),
0.0, osg::Vec3(0.0, 1.0,
0.0)));
vm.setTrans(osg::Vec3f(eyex, eyey, eyez));
viewer->getCamera()->setViewMatrix(vm);
I'm expecting to see a view of the terrain that is centered around (eyex,
eyey, eyez) and I see nothing. Can someone tell me what I'm doing wrong in
the code above?
Thanks,
-Shayne
P.S. When I use the command:
viewer->setViewMatrixAsLookAt()
with the same eye point (with lookat and up vectors), I can see the terrain
as expected.
