Read_Volume

Synopsis

read an AVS volume (.dat file) and output an AVS/Express field

Input Port

Parameters

Output Ports

Description

Read_Volume reads an Application Visualization System volume format file (.dat suffix) and converts it into an AVS/Express Field_Unif.

Input Port

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

Read vol Filename

File browser. Selects the disk file to input and convert. The default search pattern is $XP_PATH<0>/data/volume/*.dat.

The input file is an AVS volume (.dat) format binary file such as the AVS write volume module produces.

Output Ports

out

The output is a new Field_Unif object containing:

Node_Data

•      nnodes equal to the product of the dims array (X x Y x Z)
  nnode_data equals 1 (one Data_Array component)

 

Data_Array

•      nvals equals nnodes
  veclen equals 1
  values array contains the scalar node values
  primitive data type OM_TYPE_BYTE

 

Grid_Unif (portions derived from Grid_Struct)

•      ndims equal to 3 (from Dim3)
•      dims array equal to dims[0] = x dim; dims[1] = y dim; dims[2] = z dim
  points array equal to: points[0] = 0.0
  points[1] = 0.0
  points[2] = 0.0
  points[3] = (float) x - 1.0
  points[4] = (float) y - 1.0
  points[5] = (float) z - 1.0

 

Grid

•      nspace equals Space3
