thresh_null

Synopsis

remove cells with nodes that contain NULL data from input field

Input Ports

in_field	Mesh + Node_Data
ui_parent	user interface parent object

Parameters

thresh data

UIradioBoxLabel

selects data component to remove NULL cells

Output Ports

out_fld	Mesh + Node_Data
out_obj	output renderable object

Description

thresh_null removes cells where the selected component's node data is NULL. For example, to improve the performance of the renderer when rendering fields with NULL data you use thresh_null. While the renderer automatically deletes NULL data cells, it must do so every time the object is transformed. You remove this overhead using thresh_null as a data "preprocessor."

Input Ports

in_field

The input field must contain any mesh and Node_Data.

ui_parent

A port to connect to a user interface object that contains the macro's widgets. By default, it is connected to the default user interface object in the application in which the macro is instanced. (This default connection is not drawn.)

Parameters

thresh data

UIradioBoxLabel. Radio buttons to pick which component to use during the search for NULL data. The component can be scalar or vector. The default is the first (0th) component. If node data labels are present, they are displayed.

Output Ports

out_fld

The output is a field with a new, reconstructed unstructured mesh. Its new Node_Data contains all data that is not from a deleted cell.

out_obj

This is a renderable version of the output field.

Example
