The following table includes the list of all current opengl es extensions and indicates their support level. Glsl motion blur on mobile possible at acceptable framerates. Motion blur is normally not desirable, but it is sometimes hard to avoid with real cameras, because the exposure time depends for a large part on the amount of light in the scene.
It comes with its own software emulation fallback driver though. Motion blur is produced in an image when there is relative motion between subject and camera while the shutter is open blur n.

Eventually this works its way into a simple simple. In the first pass, the fastmoving geometry is rendered unblurred into a framebuffer object. Since motion blur is computed per object, the motion blur effect is specific to that object and not a true artifact of camera aperture and exposure like it is in the real world.

Motion blur happens when objects move so fast with respect to the camera, or the exposure time of a camera is so long, that during the exposure, some objects have moved more than half a pixel, and therefore appear smeared out. With todays hardware it is quite difficult to do blurring by hand using the color buffer at least in a way that is supported by all the gfx cards, so we need to do a little trick. Therefore, it is not dependent on camera motion or pose. For example i can move in the z axis back and front and also using one more glut button to move faster however when i rotate the camera in the x axis the camera rotates all right but then all movements stop and i cannot.
