CCamera& mrpt::opengl::CFBORender::getCamera

(

const COpenGLScene &

scene

)

Get a reference to the scene camera.

void mrpt::opengl::CFBORender::getFrame	(	const COpenGLScene &	scene,
		mrpt::utils::CImage &	image
	)

Render the scene and get the rendered rgb image.

Resizes the image buffer if it is necessary.
