Things You Must Know If You’re
Thinking about Visualizing and
Animating Your Simulation in
Fortran and C++ Environments…

The Demands
Are you keeping up with the trend of
dynamic visualization?

Do you know it can be done within a
few lines of codes without any windows
programming or graphics initialization?

Over 70% of effort is wasted on post-processing. Are you
looking into data processing at run-time?

Lots of researchers are already using interactive movie
presentation. Are you still presenting your work with static
graphs?


What’s MATFOR® ?

MATFOR® is a set of numerical and visualization libraries
especially designed for programmers in scientific computing
field.

MATFOR® is a new generation graphics library fully
exploiting the modules and the array features of Fortran
90/95 and C++ languages.

MATFOR® is a collection of high-level graphical procedures
developed with the mission of reducing time spent on the
program development.
5
What Does MATFOR® Do?
By adding a few lines of
MATFOR® codes to
your Fortran/C/C++
program, you can easily
visualize your
computing results,
perform run-time
animations, or even
produce an interactive
movie presentation as
you execute your
program.

Reasons that Make

8 AnCAD Incorporated
Advanced 3D Visualization
The graphics library of MATFOR®
contains high quality visualization plots
for complicated data exhibition. By
only adding a few lines of codes to call
MATFOR® graphics procedures, the
program can be visualized in threedimensional mode. The graphical
procedures include streamline, surface
plot, vector plot, contour plot, mesh
plot, slicing, isosurface, molecules plot,
And more…
9
and more.
Real-Time Animation
MATFOR® features realtime program-monitoring
mechanism to reduce
time and effort spent on
post-processing and
debugging.
The simulation can be
presented as an animation
while the calculation
proceeds and shows in the
console window.
10
• MATFOR presenting simulation while calculating the data.
Runtime Data Manipulation
MATFOR® allows manipulation of the data displayed during execution;
data can be examined with higher precision and customization at
runtime.
• Graphics Viewer
11
• Data Viewer
Interactive Movie Presentation
12
Existing
Visual
Tools
The existing visual tools mainly focus on post
processing; segments of motion pictures are
assembled in sequence and saved as a movie file.
This mechanism only allows viewers to see the
animation from one viewpoint.
MATFOR®
MATFOR® enables interactive movie presentation
by saving the simulated data into a MATFOR®defined data format. The completed video clip can
be seen from different view angles with built-in
graphical manipulation features.
Simplicity

Besides its simple and powerful visual functions, MATFOR® enables
scientists and engineers to code in Matlab fashion using the simple
calling concept in Fortran and C++ environments.
MATLAB
a = inv(x)
MATFOR a = mfInv(x)

e = eig(x)
e = mfEig(x)
Calling msSVD in MATFOR® to perform singular value decomposition
gives the same result as calling DGESVX in LAPACK. However,
MATFOR® function only takes 3 pre-initialized parameters while LAPACK
function takes 20 pre-initialized parameters.
Call DGESVX( FACT, TRANS, N, NRHS, A, LDA, AF, LDAF, IPIV, EQUED, R, C,
B, LDB, X, LDX, RCOND, FERR, BERR, WORK, IWORK, INFO )
LAPACK
Call msSVD( mfOut(A, B), C )
MATFOR
13
Standalone

Currently, the proprietary format dominates in most
visualization tools generate files that can only be
executed on one specific application.

MATFOR® possesses the ability to convert
visualization files into standalone executables.

Through the conversion, data sharing and
publishing become much easier.
Compiling and
linking the programs
with MATFOR library.
Running compiled
executables without
installing MATFOR.

MATFOR® Graphics Object I
MATFOR® utilizes the Graphics Object Oriented Programming (GOOP)
concept to enhance 3D visualization and manipulation. Especially designed to
ease maintainability, MATFOR® Graphics Object contains two attributes Data and Representation. “Data” contains the computation results and
“Representation” embraces the manipulations of the final graphs.

An exclusive Visual Tool
mfPlayer is an exclusive visual tool by which the previously saved
numerical data is read and displayed as an interactive movie presentation.
As MATFOR® saves the simulated data into a MATFOR®-defined MFA
file, mfPlayer is one approach to present the recorded animation. The
complete video clip can then be viewed from different angles.
