Hi all;

I am a newbie in POVRAY. I was wondering if there is possibility of using
POVRAY 3.5 for 2D and 3D scientific visualization? I appreciate any help
or/reference in this respect -- (I use POVRAY in Windows platform)


Thank you all.

The short answer is yes.

The long answer is a bit more difficult to give as you didn't tell us 
what kind of visualisations you are looking for and there are many 
possibilities.

Just as an example:

Nope, it is entirely impossible to use POV for anything to do with 
science. ;-)

What type of visualization are you thinking of? POV 3.5 has things such 
as isosurfaces, parametric surfaces, and a powerful scene language that 
can be used to generate meshes or other shapes to visualize equations 
and algorithms. It supports density files that can be used in the 
isosurfaces or as media densities. You could also use user-defined 
functions to control media density or to control placement or texture of 
objects.

Thank you for your input -- to be more specific -- my field of research is
Computational Fluid Dynamics and Space and Time nuclear reactor kinetics --
I generally use Tecplot (www.amtec.com) (for more sophisticated projects --
please check the demo ) and Gnuplot for simpler projects.

I see a very great potential in POVRAY for scientific visualization (am I
right?) -- So is there any tutorial  to show how  POVRAY can be used  to
produce Tecplot-like graphics? The answer is probably no -- so another
question

Is there any other learning path for this purpose? where should I start?


Thank you for your help

Christopher;

I appreciate if you provide me a learning path ---


Thanks

I meant check the Gallery Plot

There are several sample scenes in the POV-Ray distribution that could
give you some hints, for example:

advanced/float5.pov (somewhat older, showing a simple way to display
functions)
language/trace.pov (2d visualization)
textures/patterns/crackle_form.pov (3d visualization using isosurfaces)
incdemo/func_gradient.pov (vector analysis macros from math.inc)

Looking at the gallery I'd say all could be done with POV-Ray, but the
effort needed to get a result may vary. 

For learning, I would start with, at least reading, the tutorial, even
if you're not interested in reflective spheres over checkerd planes. It
will give you a basic understanding of how the scene description
language works. 

Objects you may be especialy interested in are mesh2, the heightfield, 
the isosurface and maybe blobs. For mesh you may also be interested in
3DWin at: http://www.tb-software.com/
It can convert a lot of third party mesh formats to POV-Ray's mesh 
formats.

The heightfield is image based and is usefull for things like 
http://www.amtec.com/plotgallery/3-D/3-D21.html

Isosurfaces are function based. With the latter you can plug your math
staight into POV-Ray and generate surfaces. I could be useful for
things like: http://www.amtec.com/plotgallery/V9/v9-3.html

Also of interest may be the density pattern, it uses df3-files, these
are stacks of images. The density pattern can be used with media or as
a funtion with isosurfaces.
http://www.amtec.com/plotgallery/contour/contour2.html is something
that could be done with the density pattern and media. Or 
http://www.amtec.com/plotgallery/3-D/3-D5.html 


Altough POV-Ray has a very usfull language, you'll have to be prepared
to treat your raw data with scripts and programs in such a way that
POV-Ray can deal with them. 

Looking forward to some of your results,

Ingo

Thank you -- as soon as I get some interesting result I'll upload them --
