Abstract: A method and corresponding apparatus to perform path rendering include selecting a pixel through which a path passes from among pixels included in a frame, using geometric information of the pixels in the frame. The method and corresponding apparatus include setting sub-samples for the selected pixel, and calculating a winding number of the selected pixel using the sub-samples.

Abstract: A method of rendering at least one of paths forming an object includes setting an initial value to each of tiles included in a frame based on a position and a proceeding direction of the at least one of paths, calculating a winding number of each of the tiles through which the at least one of paths passes, among the tiles included in the frame, based on the set initial value, and determining whether to perform shading based on the set initial value and the calculated winding number.

Abstract: A method and apparatus to perform tile binning for tile-based rendering include obtaining information about paths defining an object to be rendered. The method classifies one of the paths into a first group and another of the paths into a second group based on shapes of the paths, and performs the tile binning based on the classification.

Abstract: A method of performing path rendering, includes acquiring information of vertexes in an object to be rendered in a frame, and calculating a winding number of a pixel in the frame, based on a relationship between a position of the pixel and a proceeding direction of a path connecting the vertexes. The method further includes determining whether to assign a color to the pixel, based on the winding number.

Abstract: A curve rendering method includes calculating a step size based on a length of a straight line connecting a start point and an end point among control points of a curve to be rendered, and calculating initial values of a forward differencing algorithm (FDA) based on the calculated step size and coefficient values of an equation of the curve that is determined based on the control points. The method further includes generating an FDA table based on the initial values, and calculating a coordinate value of a pixel based on the FDA table.

Abstract: A method of performing path stroking includes determining whether or not aliasing based on a primitive included in a path will occur using data about the path, generating a texture to be used for performing path stroking based on a result of the determining, and mapping the texture along an edge of the primitive.
