At block 314, it may be determined whether the computer has not yet identified at least one pixel of the tile that had been identified at block 302. If the computer has not yet identified at least one such pixel, the method may return to block 304. Otherwise (e.g., the computer has identified all pixels of the tile), the method may proceed to block 316.

At block 316, it may be determined whether the computer has not yet identified at least one tile of the image (e.g., whether all tiles are not yet completed). If the computer has not yet identified at least one such tile (e.g., all tiles are not yet completed), the method may return to block 302, such that a different tile of the image can be identified. Otherwise, the method may proceed to block 317. At block 317, it may be determined whether all possible sampling is complete. If possible sampling remains to be executed, then the method returns to block 302. Otherwise, the method proceeds to block 318.

Referring now to FIG. 4, a simplified block diagram of a system 800 for creating computer graphics imagery (CGI) and computer-aided animation is shown that may implement or incorporate various embodiments of the present disclosure. The system 800 may include one or more terminals 801. The one or more terminals 801 may include hardware and software elements configured for designing CGI and assisting with computer-aided animation. The terminals 801 may be implemented as a single computing device or a set of one or more computing devices, corresponding to computer hardware and/or software.
