Hi there, I am using a custom CameraManipulator class (inheriting osgGA::MatrixManipulator) which is added to my scene after the OpenSceneGraph is initialised
The CameraManipulator has two member variables I've added, a Vec3d target and position. These are used to create a projection matrix by calling Matrix::makeLookAt. As the events are handled by the manipulator, I am updating the position/target and recomputing the matrix, then on Frame I am returning the constructed matrix. This provides a great perspective view, however I cannot work out how to construct an orthogonal projection using a target/position. In addition, I'd like to be able to change the Field Of View when I create the matrix. I realise there is a Matrix::makeOrtho and Matrix::makePerspective, however I'm not sure how to use these with my CameraLocation/Target variables. Could anyone offer me some advice? Thank you!
