Re: [osg-users] Camera control and view matrix

Hi, Robert. You've said: As for examples of manage the view matrix, there should be examples in the archives, but in the end it all boils down to not using a CameraManipulator and instead calling on each frame: viewer.getCamera()-setViewMatrix(viewMatrix); How do I stop using the default

Re: [osg-users] Camera control and view matrix

Hi Renan, The osgViewer::Viewer by default doesn't have any camera manipulators attached, but... if you call run without attaching a camera manipultor then it'll add a TrackballManipulator as a fallback to make the view usable. If you are controlling the view matrix from your own frame loop then

Here's what I do using euler angles (_camAng) and position (_camPos). osg::Quat quat(_camAng[0],osg::X_AXIS,_camAng[1],osg::Y_AXIS,_camAng [2],osg::Z_AXIS); osg::Matrix viewMat = osg::Matrix::rotate(quat) * osg::Matrix::translate (_camPos);

Re: [osg-users] Camera control and view matrix

Or just writing your own CameraManipulator, as per src/osgGA/TrackballManipulator.cpp etc. Yes, the TrackballManipulator code is a good reference for this stuff. The original post is pretty vague; perhaps the original poster would benefit from some basic OpenGL information regarding the
