This paper introduces a new algorithm that renders motion blur using triangular motion paths. A triangleoccupies a set of pixels when moving from a position in the start of a frame to another position in the end of aframe. This is a motion path of a moving triangle. For a given pixel, we use a motion path of each movingtriangle to find a range of time that this moving triangle is visible to the camera. Then, we sort visible timeranges in the depth-time dimensions and use bitwise operations to solve the occlusion problem. Thereafter,we compute an average color of each moving triangle based on its visible time range. Finally, we accumulatean average color of each moving triangle in the front-to-back order to produce the final pixel color. Thus, ouralgorithm performs shading after the visibility test and renders motion blur in real time.
