I am using modern OpenGL with glfw. I made a FPS camera with mouse and it works very well. But I want to move my mouse like Blender's model view mode. When I press the middle mouse button and move the mouse, it should move the camera. I tried it but I couldn't succeed it. I just want it like Blender. That is my camera class (sorry for indentation):

Hello, Welcome to the forums and thanks for the question! Glad you found the answer. My only addition is by default this will return Point.Empty if the specified point is outside the bounds of the image, however of course this is a perfectly valid point if the user happens to hover their mouse over the first pixel in the image.
If one zooms the mouse position is the location on the not zoomed page. But the placement pixels are the position on the new page. So one need to correct for the zoom_factor. $\begingroup$ @Patrick Moving the mouse back without releasing the mouse button while rotating an object usually leads to the same result as if the mouse had not been moved e.g. up and back down at all. I added a few words about this (pretend the mouse moved instantly to the current position). $\endgroup$ – Nero Dec 9 '15 at 21:50
