Abstract

Aspects of the present disclosure includes methods for realistic real-time motion blur of a primitive. The methods can calculate a first movement of a primitive, blur texture space data based on the first movement, cache the blurred texture space data, and re-use the blurred texture space data when later movement of the primitive calculated at a later time is found to be similar to the first movement. The methods can re-blur the texture space data to generate second blurred texture space data, store second blurred texture space data, and use the second blurred texture space data to generate blurred primitives if the later movement differs by a threshold amount from the first movement.
