20150091215 | FABRICATING LIGHTWEIGHT SKIN SYSTEMS FOR LARGE SCALE ROBOTIC CHARACTERS - A method of fabricating a skin system or its elements using a laser cutter. The laser cutter is controlled to perform multiple passes to selectively cut away layers of material on a surface of a sheet of cellular foam materials. Each layer of material to be removed is defined by a cut or texture pattern. The laser cutter is operated to cut deeper with each layer of material removed by setting a different resolution for the laser cutter for each layer. For example, a laser cutter may be selectively controlled to operate within a resolution range, and each layer defined by the same or different cut pattern is cut using a different resolution. The method includes associating lower resolution settings for the first or outer layers to remove a first depth of material from the skin sheet's surface and associating higher and higher resolution settings for additional layers. | 04-02-2015 |
20150241960 | 3D DRAWING SYSTEM FOR PROVIDING A REAL TIME, PERSONALIZED, AND IMMERSIVE ARTISTIC EXPERIENCE - A method for providing a three dimensional (3D) drawing experience. The method includes capturing a 3D image of a participant and then processing this image to key the participant's image from a background. The keyed participant's image is mixed with a 3D background image such as frames or scenes from a 3D movie, and the mixed 3D image is projected on a projection screen. For example, left and right eye images may be projected from a pair of projectors with polarization films over the lenses, and the projection screen may be a polarization-maintaining surface such as a silver screen. The user moves a drawing instrument in space in front of the projection screen, and spatial tracking performed to generate a locus of 3D positions. These 3D positions are used to create a 3D drawing image that is projected with the 3D background and participant images in real time. | 08-27-2015 |
