 | Catmull, Edwin | A subdivision algorithm for computer display of curved surfaces (CSTD-74-006) | This report presents a method for producing computer shaded pictures of curved surfaces. Three-dimensional curved patches are used, as contrasted with conventional methods using polygons. The method subdivides a patch into successively smaller subpatches until a subpatch is as small as a raster-elem... | Computer animation | 1974-12 |

 | Phong-Tuong, Bui | Illimunation of computer generated images (CSTD-73-005) | This .report describes a new model for the shading of computer-generated images of objects in general and of polygonally descibed free-form curved surfaces in particular. The shading function is determined by a linear interpolation of the curvature of the surface. It takes into consideration the phy... | Computer animation | 1973-07 |

 | Cannon, Thomas Michael | Digital image deblurring by nonlinear homomorphic filtering (CSTD-74-004) | This report is concerned with the digital estimation of the frequency response of a two-dimensional linear system through which images have been passed and blurred. Almas t no a priori Knowledge concerning the system is required, and only one blurred image is necessar\d for a successful estimation. ... | Computer animation | 1974-08 |

 | Clark, James Henry | 3-D Design of free-form B-Spline surfaces (CSTD-74-005) | This report describes an experimental system for designing free-form B-spline surfaces using a head-mounted display. In this system, the interaction with the surfaces takes place in three dimensions as the designed object's shape Is updated in real-time. The report also examines some of the problems... | Computer animation | 1974-09 |

 | Wessler, Barry David | Computer-assisted visual communication (CSTD-73-004) | The purpose of this research was to build an environment m which an author can create a visual communications vehicle (a film) which will convey his ideas and thoughts. The primary motivation for this effort was the powerful ability of film to combine instruction with entertainment. The entertainmen... | Computer animation | 1973-07 |
