20090033660 | 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 virtual object using a plurality of composite textures, each formed by blending collapsible texture layers. Texture coordinates in texture space are derived using information determined at the time of surface mesh generation. The invention features dynamic texture allocation and deallocation, allowing a user to interactively modify the shape of a painted, three-dimensional model. Finally, the invention features an architecture for combined graphical rendering and haptic rendering of a virtual object, allowing a user to experience force feedback during the painting of the object in object space. | 02-05-2009 |
20110202856 | Systems and methods for interfacing with a virtual object in a haptic virtual environment - A user of a modeling application modifies an initial virtual object using a sketch drawn on one or more construction planes. Typically, construction planes are connected by an axis that intersects the virtual object. The user can draw a sketch on each construction plane, and the modeling application interpolates a shape along the axis between the sketches to determine what material in the virtual object is to be removed from it. In this manner, material may be removed to create a recess or hole in the virtual object or otherwise to slice away material from the object. A user can use two or more axes and construction planes to produce complex shapes from the initial virtual object. A user can also select a portion of a virtual object and mirror the selected portion. Modifications that the user makes in the selected portion are made correspondingly in the mirrored portion. | 08-18-2011 |

20140333625 | Apparatus and Methods for Haptic Rendering Using a Haptic Camera View - The invention provides systems and methods for using a “haptic camera” within a virtual environment and for using graphical data from the haptic camera to produce touch feedback. The haptic camera obtains graphical data pertaining to virtual objects within the vicinity and along the trajectory of a user-controlled haptic interface device. The graphical data from the camera is interpreted haptically, thereby allowing touch feedback corresponding to the virtual environment to be provided to the user. | 11-13-2014 |

20100167316 | Enrichment of Tissue-Derived Adult Stem Cells Based on Retained Extracellular Matrix Material - Methods for enriching, detecting, or using adult stem cells through the use of recognition ligands that specifically bind to ECM components retained to the surfaces of adult stem cells are described. An ECM component such as hyaluronan that is retained to the surfaces of adult stem cells when removed from animal tissues can be used to detect a diverse population of adult stem cells based on the nature of the ECM niche region in which the adult stem cells normally reside. For example, a separation method such as magnetic separation can be used to detect and isolate or enrich adult stem cells based on a recognition ligand that is specific for an ECM component that is retained to the surfaces of adult stem cells to a greater degree than to other cells in the population. | 07-01-2010 |
