This is done copying only every n-th (n = <i>factor</i>) point of the input field into the output field. If a point is taken over to the output field its Node data is transferred as well. The cell connectivity information is not transferred to the output field. </p> <p> The macro includes a user interface. The downsize factor can be controlled from the user interface panel. </p> <h4>Inputs</h4> <p> <i><b>in</b></i> </p> <p> Reference to the input field. </p> <h4>Parameters</h4> <p> <i><b>factor</b></i> </p> <p> A member of the DVdownsize_scatParams parameter block group. This int value is used as downsize factor(n). Only every n-th point in the input mesh is transferred into the output mesh.</p> <h4>Outputs</h4> <p> <i><b>out</b></i> </p> <p> The most primitive output field of the DVdownsize_scat macro. This contains the new 3D model downsized from the input field. </p> <p> <i><b>out_obj</b></i> </p> <p> The directly renderable object that contains the output field of the DVdownsize_scat macro. This contains a DataObject object that can be rendered by the standard data viewers. The DataObject is generated directly from the field data created from the input model. </p> <h3>Utility Modules</h3> <p> The User Macro DVdownsize_scat makes use of the Functional Macro DVdownsize_scat_func and the UI Macro DVdownsize_scat_UI. </p> <h3>Files</h3> <p><i>iac_proj/dvdown/dvd_mods.v</i> contains the V definitions of the DVdownsize_scat_Params parameter block and the Downsize_core module.</p> <p><i>iac_proj/dvdown/dvd_macs.v</i> contains the V definitions of the DVdownsize_scat_func Functional Macro, the DVdownsize_scat_UI User Interface Macro, and the DVdownsize_scat User Macro. </p> <h3>Other Notes</h3> <p>The low-level DVdownsize_scatMods library containing the low-level module Downsize_core does not specify a process. By default the <tt>express</tt> process will be used.</p> <h3>Author</h3> <p> <pre> Mario Valle Advanced Visual Systems, Inc. </pre> </p> <h3>Modifications</h3> <p> <pre> Tobias Schiebeck International AVS Centre </pre> </p> <h3>Contact</h3> <p> <pre> International AVS Centre Manchester Visualization Centre Manchester Computing University of Manchester Oxford Road Manchester United Kingdom M13 9PL </pre> </p> <h3>See Also</h3> <ul> <li><a href="osl.shtml" target="_top">Oriented Streamline</a></li> </ul>  </td> </tr> </table> </td> </tr> <tr height="100%"> <td class="sideLink" width="25%" align="left" valign="top" nowrap="nowrap"> <p><a href="../../../../general/index.shtml" target="_top">General Information</a></p> <p><a href="../../../../repository/index.shtml" target="_top">Repositories</a></p> <p class="sideLinkLevel2"><a href="../../../new/index.shtml" target="_top">  New Releases</a></p> <p class="sideLinkLevel2"><a href="../../../download/index.shtml" target="_top">  Download</a></p> <p class="sideLinkLevel2"><a href="../../../submit/index.shtml" target="_top">  Submit</a></p> <p class="sideLinkLevel2"><a href="../../../pfiles/index.shtml" target="_top">  Project Files</a></p> <p class="sideLinkLevel2"><a href="../../../avs5/index.shtml" target="_top">  AVS5</a></p> <p class="sideLinkLevel2"><a href="../../../express/index.shtml" target="_top">  AVS/Express</a></p> <p class="sideLinkLevel3"><a href="../../atoz.shtml" target="_top">    A to Z</a></p> <p class="sideLinkLevel3"><a href="../../number.shtml" target="_top">    Project #</a></p> <p></p> <p class="sideLinkLevel3"><a href="../../data_io.shtml" target="_top">    Data IO</a></p> <p class="sideLinkLevel3"><a href="../../filters.shtml" target="_top">    Filters</a></p> <p class="sideLinkLevel3"><a href="../../mappers.shtml" target="_top">    Mappers</a></p> <p class="sideLinkLevel3"><a href="../../misc.shtml" target="_top">    Miscellaneous</a></p> <p class="sideLinkLevel3"><a href="../../special.shtml" target="_top">    Special Projects</a></p> <p class="sideLinkLevel2"><a href="../../../pog/index.shtml" target="_top">  Project Guidelines</a></p> <p><a href="../../../../usergroup/index.shtml" target="_top">User Group</a></p> <p><a href="../../../../training/index.shtml" target="_top">Training Materials</a></p> </td> </tr> </table> <table width="100%" border="0" cellspacing="0" cellpadding="0" bgcolor="c6c6e0"> <tr> <td><img src="../../../../img/foot1.gif" alt="IAC" width="155" height="25"></td> <td width="100%"> Last Updated:  26th November 2002 </td> </tr> </table>
