Claim 3:
4. The method of claim 3, wherein determining the camera MV0 for the selected pixel based on the world space position of the selected pixel's corresponding vertex in the previous frame comprises:
determining an eye space position of the vertex based on a depth of the selected vertex in the previous frame and a ray pointing from the virtual camera to the selected vertex on a near clip of a homogenous clip space and applying an inversed view matrix from the previous frame to the eye space position to determine the world space position;
applying a first view matrix of the current frame to the world space position to generate a position of the selected vertex in the homogenous clip space;
applying a second view matrix of the previous frame to the world space position to generate a preposition of the selected vertex in the homogenous clip space; and
calculating the camera MV0 as a difference between the position and the preposition, in each of a vertical axis, a horizontal axis, and a depth axis.
