Method and apparatus for processing image data

An image data processing apparatus comprising:

• at least one processor configured to,
• receive a plurality of image data inputs to be used to perform three-dimensional (3D) shading,
• determine at least one color component to be used to display a current pixel among a plurality of color components to be used to determine values of a plurality of pixels comprising the current pixel based on the received plurality of image data inputs, and
• determine a value of the at least one color component by using at least one operation among a plurality of operations for the plurality of image data inputs, excluding operations for color components other than the at least color one component;
• and
• a display configured to display the current pixel by using the value of the at least one color component.

A method of performing three-dimensional (3D) processing of image data, the method comprising:

• receiving, using at least one processor, image data inputs related to an image to be 3D shaded, the image data inputs including data related to color components associated with at least one pixel of the image data and a first shader and a second shader;
• determining, using the at least one processor, which of the color components are necessary to display the at least one pixel based on the second shader;
• selecting, using the at least one processor, at least one operation of a plurality of operations associated with the second shader based on the determined necessary color components of the second shader;
• generating, using the at least one processor, a combined shader based on the first shader and the second shader, the combined shader including the selected at least one operation;
• shading, using the at least one processor, the at least one pixel based on the combined shader;
• and
• displaying, using the at least one processor, the shaded at least one pixel on a display device.
