Abstract
In one embodiment, a computer-implemented method for rendering a three-dimensional computer-aided design model includes storing in a computer memory a subset of data fragments for a certain pixel location, receiving a next data fragment, and determining whether the next data fragment has a depth value indicating a position closer to a viewer than any one of the data fragments in the subset, in which case, the next data fragment replaces the data fragment in the subset having a depth value indicating a position farthest from the viewer. The subset is sorted according to respective depth values of each of the data fragments in the subset, and a blending process is performed to compute a pixel value representing a transparency characteristic of the three-dimensional computer-aided design model at the certain pixel location.
