A method for antialiasing edge pixels in a rendering operation, comprising the steps of: determining coverage of subpixels associated with an edge pixel on an edge of a polygon being rendered that is stored in a first buffer; creating an antialiasing value representing the relationship of the edge pixel to its surrounding neighbors as to the amount of color that is to be blended into the edge pixel of a color corresponding to that of its surrounding neighbors, wherein the step of creating the antialiasing value comprises the steps of: supersampling the edge pixel during rendering thereof to provide a nluralitv of subpixels, wherein each of the subpixels contains information as to coverage by the polygon; and converting the coverage pattern of the subpixels into a single antialiasing value that represents the positional relationship of the coverage as to neighboring pixels; wherein the step of creating the antialiasing value for the edge pixel is operable to further create a depth value in association with the antialiasing value, which depth value comprises the depth value of the subpixel that is covered by the foremost polygon; storing the antialiasing value in a second buffer in association with the edge pixel in the first buffer; retrieving the edge pixel and the associated antialiasing value; determining the color of at least one adjacent pixel to the edge pixel; blending the color of the at least one adjacent pixel with the edge pixel as a function of the positional relationship of the subpixels in the supersampled edge pixel to provide an antialiased pixel; and storing the antialiased pixel in a frame buffer. determining coverage of subpixels associated with an edge pixel on an edge of a polygon being rendered that is stored in a first buffer; creating an antialiasing value representing the relationship of the edge pixel to its surrounding neighbors as to the amount of color that is to be blended into the edge pixel of a color corresponding to that of its surrounding neighbors, wherein the step of creating the antialiasing value comprises the steps of: supersampling the edge pixel during rendering thereof to provide a nluralitv of subpixels, wherein each of the subpixels contains information as to coverage by the polygon; and converting the coverage pattern of the subpixels into a single antialiasing value that represents the positional relationship of the coverage as to neighboring pixels; wherein the step of creating the antialiasing value for the edge pixel is operable to further create a depth value in association with the antialiasing value, which depth value comprises the depth value of the subpixel that is covered by the foremost polygon; storing the antialiasing value in a second buffer in association with the edge pixel in the first buffer; retrieving the edge pixel and the associated antialiasing value; determining the color of at least one adjacent pixel to the edge pixel; blending the color of the at least one adjacent pixel with the edge pixel as a function of the positional relationship of the subpixels in the supersampled edge pixel to provide an antialiased pixel; and storing the antialiased pixel in a frame buffer. supersampling the edge pixel during rendering thereof to provide a nluralitv of subpixels, wherein each of the subpixels contains information as to coverage by the polygon; and converting the coverage pattern of the subpixels into a single antialiasing value that represents the positional relationship of the coverage as to neighboring pixels; wherein the step of creating the antialiasing value for the edge pixel is operable to further create a depth value in association with the antialiasing value, which depth value comprises the depth value of the subpixel that is covered by the foremost polygon; storing the antialiasing value in a second buffer in association with the edge pixel in the first buffer; retrieving the edge pixel and the associated antialiasing value; determining the color of at least one adjacent pixel to the edge pixel; blending the color of the at least one adjacent pixel with the edge pixel as a function of the positional relationship of the subpixels in the supersampled edge pixel to provide an antialiased pixel; and storing the antialiased pixel in a frame buffer.
