Graphics processing apparatus and method of processing graphics pipeline thereof

A method of processing a graphics pipeline by a graphics processing apparatus, the method comprising:

• performing pixel shading to process pixels corresponding to a three-dimensional (3D) object of a 3D image, the pixel shading being performed by a shading processor;
• texturing the object, the texturing being performed by a texturing processor;
• determining a post-processing operation mode from among a plurality of post-processing operation modes to adjust visual effects of the textured object, the determining being performed by the texturing processor;
• and
• transmitting data of the textured object to a processing path of a plurality of processing paths for the post-processing operation in accordance with the determined post-processing operation mode, the transmitting data being performed by the texturing processor,
• wherein data of the object is buffered by a reorder buffer in accordance with a processing order when the processing path for the post-processing operation bypasses the shading processor, and
• wherein the plurality of processing paths partially overlap each other.
