[osg-users] moving camera from FirstPersonManipulator/StandardManipulator without mouse button

I'm trying to adapt camera movement from FirstPersonManipulator or StandardManipulator. I've found an example here and was able to compile it. However, I can't seem to find how to move the camera when there's no mouse button pressed. How

Re: [osg-users] How to hide mouse cursor?

To make it work, I have moved it to after viewer.realize(); like that: viewer.realize(); osgViewer::Viewer::Windows windows; viewer.getWindows(windows); for(auto &window : windows) { window->useCursor(false); window->setCursor(osgViewer::GraphicsWindow::NoCursor);

Re: [osg-users] [forum] Change the position and rotation angle of the camera

Dear Robert, this doesn't answer the question. Most of us use a manipulator, so the question is: how to change camera position using a CameraManipulator. Is this possible? Rodrigo. On Thursday, April 17, 2014 at 5:22:32 AM UTC-3, Robert Osfield wrote: > > Hi Becky, > > If you viewer has a Cam

Re: [osg-users] [3rdparty] How to change camera's yaw and pitch, and move front, back and sideways according to that?

Hi Sam, I managed to implement my own manipulator (OVNIController, derived from FirstPersonManipulator), but still can't change the camera position (I want to change it in the beginning of the program, and also when the user press the Home key). You can see my code here: https://github.com/ec

Re: [osg-users] [forum] Change the position and rotation angle of the camera

Hi Becky, I managed to change the camera position using a manipulator called controller. viewer.setCameraManipulator(controller); viewer.realize(); // osg::Matrix matrix; // matrix.makeLookAt( osg::Vec3(), osg::Vec3(), osg::Vec3() ); osg::Quat quad; // matrix.get(quad);

I'm showing a large map over a terrain. In the beginning the user sees the whole map from above (call it "position 0"). I want to create an animation before that, with the camera approaching the terrain from very far, up to the initial position (position 0). Only then the user will be able to c

Thank you for your reply, Robert, but one of us is not understanding the other. "if you are reuse the same subgraph the node above the reused part like the osg::Billboard is what is unique so put your unique name on that" Actually, I have only one osg::Billboard (geodeHidreletrica) for hundreds
