Computer animation consists of a series of images each taken for a specific point in time. This can create temporal aliasing; motion, especially fast motion, appears discontinuous. Motion blur can be used to prevent a strobing effect and to enhance the perception of motion. Motion blur is commonly achieved by one of the following three methods: stretching the object along the path of motion, stochastic sampling in the time domain, and supersampling over time. When creating stereo images while using stochastic sampling, each eye sees different points on the object at a pixel location over time, creating discrepancies in the left and right views. Supersampling produces images that are averages of several disparate images of the same object, making it difficult to fuse the views. Traditional methods for creating motion blur can therefore produce images with ambiguous depth when combined with stereo. The stretched object method works well with stereo as there is consistency in both views. However, it exaggerates sizes of moving objects and lacks the blurring effect of the sampling methods. Our technique for creating motion blur in stereo is to stretch moving objects and then apply functions to give blurring effects such as transparency or fading.
