Original Abstract Submitted

recurrent blurring may be used to render frames of a virtual environment, where the radius of a filter for a pixel is based on a number of successfully accumulated frames that correspond to that pixel. to account for rejections of accumulated samples for the pixel, ray-traced samples from a lower resolution version of a ray-traced render may be used to increase the effective sample count for the pixel. parallax may be used to control the accumulation speed along with an angle between a view vector that corresponds to the pixel. a magnitude of one or more dimensions of a filter applied to the pixel may be based on an angle of a view vector that corresponds to the pixel to cause reflections to elongate along an axis under glancing angles. the dimension(s) may be based on a direction of a reflected specular lobe associated with the pixel.
