Scissors Clip Test pixel coordinates against clip rectangles and reject them if outside. A set-up engine allows drivers to pass polygons to the rendering engine in the form of raw vertex information, subpixel polygon addresses. Whereas, most common designs force the host CPU to pre-process polygons for the rendering engine in terms of delta values for edges, color, and texture. In raster graphics architecture a primitive is formed by scan conversion where each scan line intersects the primitive at two ends, P left and P right. Each pixel within the span contains the z, R, G, and B data values.
Tessellation is the process of subdividing a surface into smaller shapes.
To describe object surface patterns, tessellation breaks down the surface of an object into manageable polygons. Triangles or quadrilaterals are two usually used polygons in drawing graphical objects because computer hardware can easy manipulate and calculate these two simple polygons. An object divided into quads and subdivided into triangles for convenient calculation. Texture Anti-aliasing An interpolation technique used to remove texture distortion, staircasing or jagged edges, at the edges of an object. Texture Filtering Removing the undesirable distortion of a raster image, also called aliasing artifacts, such as sparkles and blockiness, through interpolation of stored texture images.
