| Number | Title | Issue Date |
| 7319466 | Method and apparatus for generating and interfacing with a haptic virtual reality environment A method for generating a haptic interactive representation including the steps of defining a haptic interaction space and building a hierarchical construct, for use within the haptic interaction space, using a plurality of underlying constructs. In one embodiment t... | 01/15/2008 |
| 7103499 | 3-D selection and manipulation with a multiple dimension haptic interface Systems and methods provide a user the ability to select three-dimensional virtual objects in a three-dimensional modeling environment using two-dimensional representations of the objects. In broad overview, the invention involves a multidimensional degree of freedo... | 09/05/2006 |
| 7095418 | Apparatus and methods for texture mapping The invention provides texture mapping techniques that facilitate interactive painting of a three-dimensional virtual surface by a user in object space, without requiring global parameterization. The texture mapping techniques feature rendering texture for a given v... | 08/22/2006 |
| 6958752 | Systems and methods for three-dimensional modeling Systems and methods for modifying a virtual object stored within a computer. The systems and methods allow virtual object modifications that are otherwise computationally inconvenient. The virtual object is represented as a volumetric representation. A portion of th... | 10/25/2005 |
| 6181059 | Electron source having a plurality of magnetic channels An electron source comprises a first permanent magnet having a first channel, extending between first and second poles of the magnet, the internal surfaces of the first channel being conductive. A cathode means is located in the first channel at a first p... | 01/30/2001 |
| 4027148 | Vector generator A vector generator having a digital input and a cathode ray tube (CRT) display output is disclosed. Digital values specifying the initial point of the line segment in Cartesian coordinates are converted to proportional voltages applied across the capacito... | 05/31/1977 |
