Inventor: LIANG BOB CHAO-CHU
IPC: G06F3/153
Filed: 1987-03-17
Granted: 1990-03-13
Abstract: INTERPOLATED DISPLAY CHARACTERISTIC VALUE GENERATOR Abstract of the Disclosure Method and apparatus for providing interpolated display characteristic values, such as intensity or Z value, for pels within a polygon to be displayed by a computer graphics display system. A scanning sequence generates pel addresses such that each pel address so generated is contiguous with a previously generated pel address. The parametric value rate of change in both the X and the Y direction is determined, and expressed as an integer value and a remainder quantity. The remainder quantity is used to determine a sequence, driven by pel address changes, by which the integer parametric value increment from pel to pel is incremented or decremeted by one in a regular sequence that assures that the error in the computed parametric value for each pel never exceeds 0.5 parametric value units.

Title: Method and apparatus for production of three-dimensional objects by photosolidification
Inventor: FUDIM EFREM V
IPC: G03F7/20
Filed: 1988-02-24
Granted: 1993-06-22
Abstract: METHOD AND APPARATUS FOR PRODUCTION OF THREE-DIMENSIONAL OBJECTS BY PHOTOSOLIDIFICATION ABSTRACT A method for forming three-dimensional objects com-prises irradiating an uncured photopolymer by transmit-ting an effective amount of photopolymer solidifying radiation through a radiation transmittant material which leaves the irradiated surface capable of further cross-linking so that when a subsequent portion is formed it will adhere thereto. In another embodiment other means of preserving subsequent cross-linking are used instead of the transmittant material. Using either method three-dimensional objects can be made layer by layer or point by point. SPECIFICATION This invention relates generally to improvements in a method and apparatus for production of three-dimensional objects. More specifically, it relates to a method and apparatus for forming three-dimensional objects by the irradiation of photopolymers that solidify in response to radiation. All of the commonly practiced processes for fabri-cating three-dimensional objects have disadvantages. For example, the mechanical removal of material to form such objects involves much energy, time and processing; the chemical machining to form such objects has depth limitations and the incapability of making complex shapes; and the thermal molding requires expensive molds; it is very inflexible and it takes much time and energy.
