Abstract: A method of removing an intersection test error in ray tracing includes obtaining an intersection by performing an intersection test on a ray and a primitive; determining location information of the intersection indicating whether the intersection is located inside or outside an object; determining an intersection error based on comparing the location information of the intersection to path information of the ray.

Abstract: A method of performing path rendering includes selecting a tile including a path from tiles in a frame based on tile bin data, splitting the selected tile into a plurality of first sub-tiles, selecting a first sub-tile that does not include the path from the plurality of first sub-tiles, and updating an initial winding number of the selected first sub-tile. The tile bin data includes an initial winding number of each of the tiles in the frame.
