    摘要： Methods and apparatus are disclosed for the rapid creation of wire frame representations of 3-dimensional objects using generic wire frames which are prototypical of a class of objects and which are modifiable to correspond to a specific instance of the class. A set of generic wire frames are bundled as a tool kit with software for editing wire frames. A method of morphing from a source 3-dimensional stereo rendered wire frame to a target rendered wire frame is also disclosed and the apparent camera viewpoint can change during morphing.

    摘要： The disclosed calibrated ASV measurement apparatus provides accurate measurements of the ASV (apparent surface voltage) on a photoconductive imaging medium using a relatively low cost, commercially available ASV probe. To obtain accurate ASV measurements, the probe sensitivity (relating probe voltgage output to sensed potential) is periodically recalibrated to compensate for changes in environmental and electrical conditions. The calibration function is implemented using a calibration target mounted directly to the housing of the probe's sensing head so as to occupy a portion of the probe's sensing field. During periodic calibration intervals, when the ASV probe is responsive only to potentials on the calibration target, known potentials are applied to the calibration target, and an indication of a change in probe sensitivity with respect to the calibration target is calculated and used to recalibrate the value for probe sensitivity used in ASV measurement. During periodic ASV measurement intervals (with the calibration target at ground potential), the ASV probe is exposed to a reference ground and to the ASV on the imaging medium to obtain a differential probe voltgage, and this differential voltage is translated using the calibrated probe sensitivity into the desired ASV measurement relative to the reference ground. For a preferred embodiment, the periodic ground reference potential is provided by a grounded seam on the surface of the electrophotographic drum, such that separate means for that purpose are not required to be provided as part of the ASV probe.

    摘要： A viewer for viewing stereo images either downloaded over a network, such as the Internet, or resident on a personal computer uses a graphical user interface (GUI) to facilitate the display of wireframes with or without texture applied in a variety of formats. In stereo mode, the GUI permits adjustment of the neutral plane and of camera offset. The file sizes utilized with the viewer are very small and permit rapid transmission over a network. The files contain wireframe information, texture map information and animation information.

    摘要： In the capture and display of three dimensional images, techniques are provided for controlling the amount of disparity between left and right images used to create a three dimensional representation to permit three dimensional perception which would otherwise be lost as disparity increased beyond psychological and physiological limits. Both mechanical and electronic means for controlling disparity are shown. Techniques are disclosed for creating three dimensional animations which utilize disparity control for adjusting the perceived depth of an object vis-a-vis a neutral plane. When zooming in on an object with a stereo camera pair, the shift in focal length accompanying the zoom is accompanied by a simultaneous shift in disparity so that the stereo effect is not lost when a target object is very close, a moderate distance, or very far from the cameras. Camera separation is changed as a function of target distance to maintain a fixed fraction of the target distance as a default. The default can be overridden by adjusting disparity independently of the default. Personal discomfort which often accompanies viewing of stereo images is reduced by maintaining camera axes parallel so that unnecessary vertical shift is minimized or eliminated.

    摘要： A toner module has a mixing roller and a decorator roller. The decorator roller, which extends partially through a developer opening, has a partial magnetic core enclosed by a developer carrying sleeve. Developer is removed by orientating a nonmagnetic portion of the core toward the developer opening. The decorator roller is then rotated so that the sleeve carries the used developer over the nonmagnetic portion, thereby allowing the developer to fall out of the toner module. New developer is added by orientating the magnetic portion of the core to face the developer opening. The decorator roller is then rotated so that, as the sleeve rotates over the developer to be added, the magnetic force of the developer core pulls the developer onto the sleeve and into the toner module. Orientating a magnetic portion of the mixing roller proximate to the decorator roller causes the developer to be carried further into the toner module, so as to provide for more storage volume for the developer.
