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.
Claims35
A method of performing path rendering, the method comprising:
- acquiring information of vertexes in an object to be rendered in a frame;
- 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;
- and
- determining whether to assign a color to the pixel, based on the winding number.
An apparatus configured to perform path rendering, the apparatus comprising;
- an acquisition unit configured to acquire information of vertexes in an object to be rendered in a frame;
- an operation unit configured to calculate 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;
- and
- a determination unit configured to determine whether to assign a color to the pixel, based on the winding number.
An apparatus configured to generate a winding number of a pixel in a frame, the apparatus being connected to a graphics processing unit that performs path rendering, and the apparatus comprising:
- a processor configured to
- receive information of coordinates of a vertex of a path and information of coordinates of the pixel, from the graphics processing unit,
- calculate a winding number of the pixel, based on the information, and
- output the winding number to the graphics processing unit.
An apparatus configured to perform path rendering, the apparatus comprising:
- an operation unit configured to calculate a winding number of a pixel, based on a direction of a path connecting vertexes of an object, the path being at a side of the pixel;
- and
- a determination unit configured to determine whether to assign a color to the pixel, based on the winding number.
