Abstract: An example method includes, responsive to identifying an object and a reflection surface: identifying a reflection incidence point on a current position of the reflection surface; reprojecting the reflection incidence point using a surface motion vector of the reflection incidence point to determine a previous reflection incidence point. The previous reflection incidence point is a reflection incidence point on a previous position of the reflection surface. The method further includes, reprojecting a reflected point (a reflection of the object in accordance with the reflection surface's current position) using a motion vector to determine a previous location of the reflected point on the previous position of the reflection surface; projecting a current view point onto the previous position of the reflection surface to produce a previous view point; and presenting to a user a presentation of the previous location of the reflected point on the previous position of the reflection surface.
