Method and apparatus with adaptive super sampling

An adaptive super sampling apparatus, the apparatus comprising:

• one or more processors;
• memory storing instructions configured to cause the one or more processors to:
• render frames of a 3D medel object including a current frame and a previous frame;
• to determine motion vectors indicating a correspondence relationship between pixels comprised in the current frame and the previous frame;
• generate a first G-ID map and a second G-ID map respectively corresponding to the current frame and the previous frame based on geometric properties elements of the 3D object associated with the pixels in the current frame and the previous frame, each G-ID map comprising identifiers of the geometric elements of the 3D object;
• based on the motion vectors and the first and second G-ID maps, generate an artifact map indicating where artifacts will occur during super sampling of the current frame;
• and
• perform adaptive super sampling on the current frame based on the artifact map.

A method comprising:

• receiving a current frame and a previous frame rendered from a 3D object comprising data;
• generating motion vectors based on the current frame and the previous frame;
• determining first associations between pixels of the current frame and identifiers of 3D geometric elements of the 3D object;
• determining second associations between pixels of the previous frame and the identifiers of the geometric elements of the 3D object;
• determining which regions of the current frame to perform inter-frame super sampling on based on comparing the first associations with the second associations.
