One more ‘hmm’ series experiment.

Motion Blur as a Post Processing Effect.

This is based on an article from GPU Gems 3, which basically takes the motion for each pixel and computes a velocity from the difference with the previous position to sample the rendered scene texture and compute the final color. It works only for camera movement, meaning, if the camera does not move but you have a moving/rotating object in front of you the effect won’t apply.

This two videos shows camera lookat point motion, meaning it randomly looks at different points every second, and the second video shows a camera spinning around a sphere objectwith increasing velocity to reach a maximum blur state. Both are using camera motion as i stated it’s important, anyway, it should give an idea of the effect.
