摘要： A graphics data processing method and apparatus are disclosed. The graphics data processing method includes determining a guard band region having a distance range which is predetermined in a viewing direction from a position of a virtual camera, outside a virtualization region representing regions of objects able to be displayed on a screen among a plurality of objects included in graphics data. The method further includes acquiring position information of each of the plurality of objects, determining a region where at least one object among the plurality of objects is located, based on the acquired position information, and performing at least one of clipping and culling on data of the at least one object, based on the determined region.

摘要： 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.

摘要： 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.

摘要： The electric pen device includes an optical system including a lens and an image sensor configured to convert an image signal of light that has passed through the optical system to an electrical signal. The electric pen device includes a control board configured to interact with an electronic device and a communication module configured to communicate by wire or wirelessly with the electronic device, so that an image or a picture taken by a camera is confirmed and an optical zoom is controlled from the external electronic device.

摘要： 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.
