![]() | 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 |

![]() | 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 |
