This code converts an ascii VTK file to a raw binary file.

Input File:

The input file can be either of the followings:

Output file:

The output file has *.raw file extension and can be stored as either an ASCII file or a binary file.

Converted Arrays:

The content of files that will be converted are all vtkDataArrays in the vtkPointData. The arrays can consist of:

• All scalar arrays
• All vector arrays
• All normal arrays
• All tensor arrays
• All field data arrays.

Each array may has different number of components. But all arrays should have the same number of tuples.

Output Arrays:

The output is written to the output file as following:

The output array is an array of size:

"Number of total components of all arrays" x "number of tuples".

where, the "Number of total components of all arrays" is the sum of number of components of all arrays. If we have found three Arrays:

Array A: size a * m
Array B: size b * m
Array C: size c * m

Then the output array is of size (a+b+c) * m, and is written as follow : Column 1 Column 2 Column 3

First row:    A11 A12 A13 ...  B11 B12 B13 ...  C11 C12 C13 ...
Second row:   A21 A22 A23 ...  B21 B22 B23 ...  C21 C22 C23 ...
              <-- a times -->  <-- b times -->  <-- c times -->
              ...
              ...
m-th row:     Am1 Am2 Am3 ...  Bm1 Bm2 Bm3 ...  Cm1 Cm2 Cm3 ...

1. Install GNU GCC compiler, OpenMP, and Cmake:

   sudo apt-get install g++ libomp-dev cmake -y
   

2. Install VTK development:

   sudo apt install libvtk5-dev -y
   

   Alternatively, download VTK and compile it.

Get the source code

git clone [email protected]:ameli/vtk2raw.git
cd vtk2raw

Compile in ./build directory

mkdir build
cmake -B build .
make -C build

After the compilation, the executable file is located in ./bin/vtk2raw.

./bin/vtk2raw  InputFileName.vtk  OutputFileName.raw  <BinaryOutputFile>

The argument BinaryOutputFile is optional, it can be either 0 or 1 to indicate whether the output file should be ASCII or binary, respectively.
