# mia-3dvfcompare(1)

Compare two Vectorfields.

## NAME

mia-3dvfcompare - Compare two Vectorfields.

## SYNOPSIS

**mia-3dvfcompare -1 \<in-file-1\> -2 \<in-file-2\> \[options\]**

## DESCRIPTION

**mia-3dvfcompare** Compare two vector fields and print the out the difference norm per pixel to cout it it is larger than delta.

## OPTIONS

- \-1 --in-file-1=(input, required); io

  input vector field 1\
    For supported file types see PLUGINS:3dvf/io

- \-2 --in-file-2=(input, required); io

  input vector field 2\
    For supported file types see PLUGINS:3dvf/io

- \-d --delta=0

  Maximum difference between vector to be ignored

### Help & Info
