I wish to implement a zoom-to-mouse-position-with-scrollwheel-algorithm for a CAD application I work on. A more elegant solution would be to modify the projection matrix for the zooming. I tried to implement this, but only got a zoom to the center of the window working.Drag the mouse vertically in the viewport to zoom in/out (with left mouse button down). Note: It is not true zooming (of the fov), but a translation (dolly) of the ‘camera’ backwards and forwards that produces the zooming effect. Dec 12, 2008 · Possible Values. normal: No magnification is applied. The object is rendered as it normally would be. [number]: Positive floating point number indicating a zoom factor. Numbers smaller than 1.0 indicate a “zoom out” or size reduction effect, while numbers greater than 1.0 indicate a magnifying effect. Ctrl - right mouse button click: Zoom down around the clicked point. Left mouse button drag: Holding the left button down and moving the mouse will pan the image, if it is zoomed bigger than will fit in the window. Shift - left mouse button drag: Draw a line for measuring a distance or angle. Press and hold the shift key, then press the left mouse button at the starting point of the line.
It is sometimes useful to get a ray corresponding to a screen position and then move the camera along that ray.

For an FPS, use OpenTK.Input.Mouse.GetState() with CursorVisible = false. Does not work on mac with an external mouse. The trackpad works fine, but the external mouse does not change the reported position from OpenTK.Input.Mouse.GetState(). The first set of coordinates is called world coordinates, the second one camera coordinates. Sometimes it is needed to convert between the two coordinate systems, for example to get the position of a mouse click in the game world in a strategy game, or to see if an object is visible on the screen.
