摘要： 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.

摘要： 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.

摘要： 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. Thus, the voltage applied to the needle electrode (12) can be regulated by applying an electric current to the circuit and dropping the voltage with resistance 32 and resistance R.sub.1.
