Reduces the number of points in a Mesh. The module does not write any cell-connectivity information. The output of this module is a Point-Mesh which can be be used as coordinates for a glyph module.

The DVdownsize_scat reduces the Number of points in a point mesh. This is done copying only every n-th (n = factor) 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.
The macro includes a user interface. The downsize factor can be controlled from the user interface panel.
in
Reference to the input field.
factor
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.
out
The most primitive output field of the DVdownsize_scat macro. This contains the new 3D model downsized from the input field.
out_obj
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.
The User Macro DVdownsize_scat makes use of the Functional Macro DVdownsize_scat_func and the UI Macro DVdownsize_scat_UI.
iac_proj/dvdown/dvd_mods.v contains the V definitions of the DVdownsize_scat_Params parameter block and the Downsize_core module.
iac_proj/dvdown/dvd_macs.v contains the V definitions of the DVdownsize_scat_func Functional Macro, the DVdownsize_scat_UI User Interface Macro, and the DVdownsize_scat User Macro.
The low-level DVdownsize_scatMods library containing the low-level module Downsize_core does not specify a process. By default the express process will be used.
