DVread_vol

Synopsis

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

module DVread_vol {
string+Iparam filename; /* .dat file */
Mesh_Unif+Dim3+Space3+Node_Data+Scalar+Byte
+Oparam out; /* output field */
method+notify_val+notify_inst upd_read_vol<status=1>

};

Description

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

Input

filename

A string. Names the input file to be read as a .dat format file. The string can be either the complete absolute pathname, or a relative pathname. If it is relative, it will be interpreted relative to the user's working directory when AVS/Express was started.

Output

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_BYTEGrid_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 equal Space3
