Talk:Scientific visualization

A new start

Hi, I have rewritten this article from scratch, focusing on the new field of science, which emerged as subfield of computer graphics in the 1980s. It is especially not my intention that this article is going to develop as a main article about visualization in science. This was the problem with the first article here.

This new article is part of the development of a series of new articles, thematically:

• Visualization
• Data visualization
• Educational visualization
• Information visualization
• Knowledge visualization
• Scientific visualization - now established 11 July 2008
• Visual analytics - established 26 June 2008

And biographical articles, new and or improved:

• Jacques Bertin • Maxine D. Brown • Stuart Card • Donna Cox • Thomas A. DeFanti • Michael Friendly • Nigel Holmes • Jock D. Mackinlay • Michael Maltz • Bruce H. McCormick • Charles Joseph Minard • Otto Neurath • William Playfair • Clifford A. Pickover • Lawrence J. Rosenblum • Adolphe Quetelet (not yet) • George G. Robertson • Ben Shneiderman • Edward Tufte (not yet)

And the creation of several new categories in wikicommons, and finding new images.

I hope this will improve the Wikipedia representation on visualisation, and all it's aspects. -- Marcel Douwe Dekker (talk) 23:52, 11 July 2008 (UTC)

Core topics of scientific visualization

The current "Scientific visualization topics" is intended to give an overview of the core topics/issues of scientific visualization. In the development of this section I compared the following three sources:

1. The various aspects of Scientific visualization according to Daniel Thalmann (1990)

• graphics workstations and processors,
• covers fundamental problems of computational geometry,
• various aspects related to representing volume and special methods for modeling natural objects.
• Particle systems and modular maps,
• basic and advanced techniques in computer animation, and robotics methods for task-level and behavioral animation.
• applications of visualization and graphics simulation,
• and computer vision.

2. The discipline of Scientific visualization includes, according to Charles D. Hansen (2004)

• Virtual environments for visualization
• Basic visualization algorithms
• Large-scale data visualization
• Scalar data isosurface methods
• Visualization software and frameworks
• Scalar data volume rendering
• Perceptual issues in visualization

3. In a 2006 workshop held at Schloss Dagstuhl, Germany leading experts in scientific visualization included topics as

• user issues in visualization,
• large data visualization,
• unstructured mesh processing for visualization,
• volumetric visualization,
• flow visualization,
• medical visualization
• and visualization systems.

4. The Scientific Visualization Tutorials from Georgia Tech mentions the following Scientific visualization techniques

• Information visualization
• Computer simulation and Steering
• Visual Pictures
• Color coding
• Surface rendering: Dot Surface, Wire Frames, Polygonal Surface, Stacked Contour Maps, Ribbons and Streamers, Shaded Contour, Hedgehogs and Attribute Mapping
• Volume visualization
• Volume rendering techniques
• Data Types
• Animation

Further comment

In the article I made a synthesis between the data in these sources, and the related subjects present in the current Wikipedia. -- Marcel Douwe Dekker (talk) 20:08, 13 July 2008 (UTC)

Publications in the further reading section

The content of all present publications listed in the further reading section has been checked:

• Bruce H. McCormick, Thomas A. DeFanti and Maxine D. Brown (eds.) (1987). Visualization in Scientific Computing. ACM Press.
• Gregory M. Nielson, Hans Hagen and Heinrich Müller (1997). Scientific Visualization: Overviews, Methodologies, and Techniques. IEEE Computer Society.

Maybe even more important, specific publications about information visualisation, and computer graphics have been removed. This list should only apply to publications that really relate to this field. I hope we can keep it this way. -- Marcel Douwe Dekker (talk) 20:17, 13 July 2008 (UTC)

Redirection of citation

In "1980s : The foundation", an excerpt of "Visualization in Scientific Computing", Computer Graphics 21,6 (November 1987), is cited through "The Synthetic Image as Language", - I do not know why this is necessary. First we are told that the excerpt comes from The Synthetic Image as Language, and then appended to the excerpt is a reference to the Computer Graphics article.

I do not dispute that The Synthetic Image as Language adds to this article (it is an excellent piece), but it does so in a confusing and convoluted way. Rather than simply rework this to omit the reference-by-proxy, I'd like to just make a note of it, in the hopes that some better solution is found.

Cheers, Wyatt Carss —Preceding unsigned comment added by 131.104.48.230 (talk) 19:58, 29 July 2008 (UTC)

Thanks. I made some rearrangement. The double redirect is fanished this was. -- Marcel Douwe Dekker (talk) 20:33, 29 July 2008 (UTC)

No more Rainbow

Many of the images on the visualization page now make use of the infamous rainbow color map. It's generally agreed upon that this is a poor quality color map and liberally throwing it around on the Wikipedia article about scientific visualization is not such a great idea. More information about why the color map is bad can be found in the articles "Data visualization: the end of the rainbow", IEEE Spectrum 35,12, pp. 52-59, 1998 and "Rainbow Color Map (Still) Considered Harmful", IEEE Computer Graphics and Applications 27,2, pp. 14-17, 2007. Images using this color map should be replaced or removed. 130.161.157.67 (talk) 13:41, 15 September 2008 (UTC)

Sorry. I don't see the problem here? Just removing the images here seems out of the question for now. But if you have better replacements, please let me know. -- Marcel Douwe Dekker (talk) 14:33, 15 September 2008 (UTC)

Image copyright problem with File:Cliffflit.jpg

The image File:Cliffflit.jpg is used in this article under a claim of fair use, but it does not have an adequate explanation for why it meets the requirements for such images when used here. In particular, for each page the image is used on, it must have an explanation linking to that page which explains why it needs to be used on that page. Please check

• That there is a non-free use rationale on the image's description page for the use in this article.
• That this article is linked to from the image description page.

This is an automated notice by FairuseBot. For assistance on the image use policy, see Wikipedia:Media copyright questions. --05:16, 7 February 2009 (UTC)

Removed red links

I removed the following red links from the article:

Persons

• Thomas Ertl
• Charles (Chuck) Hansen
• Arie Kaufman
• David Laidlaw
• Jarke J. van Wijk

Subjects

• Computer Graphics Forum
• IEEE Transactions on Visualization and Computer Graphics

Links in an article like this should be restrickted to people with an Wikipedia article. That is the whole idea here. -- Marcel Douwe Dekker (talk) 23:05, 19 May 2009 (UTC)

I will check these persons some more:

Thomas Ertl

• Prof. Dr. Thomas Ertl
• Position: Full professor of computer science at the University of Stuttgart
• Head of the Visualization and Interactive Systems Institute (VIS)
• Head of the Visualization Institute of the University of Stuttgart (VISUS)
• Source: [1]

Charles (Chuck) Hansen

• Professor of Computer Science, School of Computing, University of Utah

So I guess there is little doubt these are notable persons in the field of Scientific visualization, who all seem worthy to have an own Wikipedia article. However the right procedure here remains, to first start such an article and then add it to the article here. -- Marcel Douwe Dekker (talk) 23:17, 19 May 2009 (UTC)

Matlab

Shouldn't we add Matlab to the software section.--37.8.3.27 (talk) 22:20, 30 September 2013 (UTC)

Difference between scientific visualization and scientific illustration?

There is a page called Scientific illustration, which redirects to Illustration#Scientific and not to this article. So, is there and difference between scientific visualization and scientific illustration? —Kri (talk) 13:00, 15 June 2018 (UTC)

In my experience, scientific visualization is data visualization as it is applied to scientific data, that is, the algorithm generation of images or animations from data. Examples might be plotting of data, or animations generated from fluid simulations, or circos plots of genetic data. Illustration is the creation of a simplified diagram to picture a scientific object of interest--the wavefront of a particle beam, or, the nervous system of a fly, or botanical illustrations, or an artist's impression of Cassini orbiting Saturn, etc. --Mark viking (talk) 17:12, 15 June 2018 (UTC)
