关闭漫游器:在使用 setViewMatrixAsLookAt 函数之前,通常需要关闭相机的漫游器(Camera Manipulator)。这是因为漫游器会自动更新相机的观察矩阵,从而覆盖你通过 setViewMatrixAsLookAt 设置的参数。可以通过调用 viewer->setCameraManipulator(NULL) 来关闭漫游器。 坐标系:OSG 使用右手坐标系,其中 X 轴向右,Y 轴向上...

1、对于场景漫游器_cameraManipulator,执行其 setNode 函数和 home 函数,也就是设 置漫游器对应于场景图形根节点,并回到其原点位置。不过在我们使用 setCameraManipulator 函数时也会自动执行同样的操作。 2、将场景图形赋予主摄像机_camera,同时设置它对应的渲染器(Renderer)的相关函 ...
如果总结为一句话,应该是:CameraManipulator是EventHanler的子类,EventHandler本身也可以实现漫游功能,只不过osg开发者为了更加丰富便捷的控制事件与漫游,从而单独设计了一个漫游操作器,以便使用者能够更加轻松方便的控制自己的场景。 清除camera中的深度缓存:camera->setclearMask(GL_COLOR_BUFFER_BIT | GL_DEPTH); ...
