The article explores the concept of motion blur, going beyond traditional approaches to create an infinite motion blur animation using a torusphere accelerator in a real-time shader. By integrating volume motion blur, the animation combines an orbiting sphere and a rotating torus to achieve essentially infinite speed blur. The shader method may not be photorealistic but offers real-time performance for long motion trails. The process involves finding motion-blurred density for orbiting shapes in polar coordinates, taking into account speed and time intervals. The unique approach challenges conventional camera simulations to create a natural and seamless motion blur effect on the screen.
