[osg-users] How can I get last frame time inn order to create indepent FPS aniamtions?

[Ricardo Ruiz]

Hi all.

How can I get last frame time inn order to create indepent FPS aniamtions?

For instance, something like m_last_time_frame:



Code:

	double angle=0;
	while (!viewer.done()) {
		angle=angle+0.1*m_last_time_frame;
		viewer.getCamera()->setViewMatrixAsLookAt(osg::Vec3(0,-400,150), osg::Vec3(0,0,0), osg::Vec3(0,0,1));
		viewer.getCamera()->setViewMatrix(osg::Matrix::rotate(angle*DEG_TO_RAD,0,0,1)*viewer.getCamera()->getViewMatrix());
		viewer.frame();
	}




Thanks.
