interp_data_to_unif

Synopsis

use coordinates from a uniform probe mesh as sample points to interpolate data.

Input Port

in_field

Mesh + Node_Data

in_probe

Uniform Mesh

ui_parent

user interface parent object

Parameters

interpolate components

UIoptionBoxLabel

data components to interpolate

Output Port

out_fld

Uniform_Mesh + Node_Data

out_obj

output renderable object

Description

interp_data uses the coordinates specified in an uniform input mesh (in_probe) as a set of sample points for a uniform field. It takes each set of coordinates in the mesh (the sample points), locates these same coordinates in the input field, then calculates what the interpolated data value of the selected component would be at that exact location based on the values of the same component in the adjacent nodes.

Input

in_field

The input is any mesh type with Node_Data.

in_probe

A uniform mesh whose coordinates represent the sample points.

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.)

ui_radiobox

Selects the algorithm for faster versus better quality. See Algorithm below

Parameters

interpolate components

UIoptionBoxLabel. A set of option buttons to pick which data components of the input field to interpolate. The default is the first (0th) component. If node data labels are present, they are displayed.

Output Port

out_fld

The output is a field that is a reference to the merge of the input probe's in_probe mesh, and a new Node_Data object with values consisting of the interpolated component values.

out_obj

This is a renderable version of the output field.

Algorithm

"faster" - For each probe point identify the first cell from from the 'in' field that passes a simple bounding box test. Then loop over the nodes of the cell and do a distance test to determine which node value to use as the value of the output point.

"better quality" - Use the same algorithm as interp_data and DVinterp_data.
