Rasterization engine and three-dimensional graphics system for rasterizing in order adapted to characteristics of polygon

#This application claims the benefit of Korean Patent Application No. 10-2007-0126848, filed on Dec. 7, 2007, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

#The present invention relates to a rasterization engine and three-dimensional (3D) graphics system, and more particularly, to a rasterization engine and 3D graphics system for performing rasterization in order adapted to the characteristics of a polygon, such as use or non-use of texture mapping, use or non-use of alpha blending, and relationship with an adjacent polygon.

#Three-dimensional (3D) graphics are graphics that show objects in three dimensions, instead of two dimensions, and are used in movies using special effects, geological analysis, and architecture or car designing using computer aided design (CAD). Recently, 3D graphics are being used to construct game screens.

#The present invention will become more apparent in view of the attached drawings and accompanying detailed description. The embodiments depicted therein are provided by way of example, not by way of limitation, wherein like reference numerals refer to the same or similar elements. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating aspects of the invention. In the drawings:

#FIG. 1 is a block diagram of an embodiment of a 3D graphics system according to some aspects of the present invention;

#FIG. 2 is a flowchart of an embodiment of operations of the 3D graphics system illustrated in FIG. 1, according to some aspects of the present invention;

#Embodiments in accordance with the present invention will now be described more fully hereinafter with reference to the accompanying drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity. Like numbers refer to like elements throughout.

#It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

#It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first signal could be termed a second signal and, similarly, a second signal could be termed a first signal without departing from the teachings of the disclosure.
