  • Patent number: 8217936
    Abstract: A method, system, and computer-readable storage medium are disclosed for minimizing tessellation of surfaces. A first plurality of polygons may be generated, wherein the first plurality of polygons are adjacent to a plurality of exterior curves of a surface. Each of the first plurality of polygons comprises at least one outside edge approximating a portion of one of the exterior curves within a first flatness tolerance. A second plurality of polygons may be generated, wherein the second plurality of polygons are on the interior of the surface. Each of the second plurality of polygons comprises a plurality of inside edges approximating portions of interior curves of the surface within a second flatness tolerance. The first flatness tolerance may be smaller than the second flatness tolerance.
    Type: Grant

  • Patent number: 7948489
    Abstract: A method, system, and computer-readable storage medium are disclosed for minimizing tessellation of surfaces. A first plurality of polygons may be generated, wherein the first plurality of polygons are adjacent to a plurality of boundaries of a surface. Each of the first plurality of polygons comprises at least one outside edge approximating a straight line within a first flatness tolerance. A second plurality of polygons may be generated, wherein the second plurality of polygons are on the interior of the surface. Each of the second plurality of polygons comprises a plurality of inside edges approximating the straight line within a second flatness tolerance. The first flatness tolerance may be smaller than the second flatness tolerance.

  • Patent number: 6043831
    Abstract: There is provided an electrostatic recording head capable of moderating variable density striations generated on a recording blank form. In an applied voltage regulating unit, a closed circuit is formed by connecting a regulator (42), a resistor (32), a diode (34) and a resistance (R.sub.1) and a transistor (T.sub.1) provided in a driving circuit (16 or 18) in series in one needle electrode (12). Here, a cathode side of the diode (34) is connected to the needle electrode (12), and another end of the regulator (42) is connected to the driving circuit (16 or 18). A regulated voltage determining means (44) determines the voltage to be applied to each needle electrode (12) in accordance with the picture image density detected by a picture image density detecting unit (46) and the humidity detected by a humidity sensor (48), and regulates a voltage value of a regulator (42) based on the determined voltage.
