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.
Claims6
A Graphics Processing Unit (GPU) for rendering an object including a path, the GPU comprising:
- a vertex shader configured to obtain path data including information about vertices included in the path and a command corresponding to the path from a global memory, calculate a final winding number of each of tiles included in a frame based on the path data and determine, for each tile, whether to perform shading based on the final winding number of the tile;
- and
- a pixel shader configured to perform shading on each of pixels included in the frame based on a result of the determining.
