REFLECTION-VISUALIZATION

CHALLENGE SELECTION

The first tool used is Visualization tool to understand the given problem in a  easy way. Visualization or visualisation  is any technique for  creating images, diagrams, or animations to communicate a message.  Visualization through visual imagery has been an effective way to  communicate both abstract and concrete ideas since the dawn of humanity.  Examples from history include cave paintings, Egyptian hieroglyphs,  Greek geometry, and Leonardo da Vinci's revolutionary methods of  technical drawing for engineering and scientific purposes.

Visualization today has ever-expanding applications in science, education,  engineering (e.g., product visualization), interactive multimedia, medicine,    etc. Typical of a visualization application is the field of computer graphics.  The invention of computer graphics (and 3D computer graphics) may be the  most important development in visualization since the invention of central  perspective in the Renaissance period. The development of animation also  helped advance visualization.

APPLICATION

Scientific visualization

As a subject in computer science, scientific visualization is the use of  interactive, sensory representations, typically visual, of abstract data to  reinforce cognition, hypothesis building, and reasoning. Scientific  visualization is the transformation, selection, or representation of data from  simulations or experiments, with an implicit or explicit geometric structure,  to allow the exploration, analysis, and understanding of the data. Scientific  visualization focuses and emphasizes the representation of higher order data  using primarily graphics and animation techniques.[5][6] It is a very  important part of visualization and maybe the first one, as the visualization  of experiments and phenomena is as old as science itself. Traditional areas of  scientific visualization are flow visualization, medical  visualization, astrophysical visualization, and chemical visualization. There  are several different techniques to visualize scientific data, with isosurface  reconstruction and direct volume rendering being the more common.

Data visualization

Data visualization is a related subcategory of visualization dealing  with statistical graphics and geospatial data that is abstracted in schematic  form.

Educational visualization

Educational visualization is using a simulation to create an image of  something so it can be taught about. This is very useful when teaching about  a topic that is difficult to otherwise see, for example, atomic structure,  because atoms are far too small to be studied easily without expensive and  difficult to use scientific equipment.

Knowledge visualization

The use of visual representations to transfer knowledge between at least two  persons aims to improve the transfer of knowledge by using computer and  non-computer-based visualization methods complementarily.[8] Thus  properly designed visualization is an important part of not only data analysis  but knowledge transfer process, too.[9] Knowledge transfer may be  significantly improved using hybrid designs as it enhances information  density but may decrease clarity as well. For example, visualization of a  3D scalar field may be implemented using iso-surfaces for field distribution  and textures for the gradient of the field.[10] Examples of such visual formats  are sketches, diagrams, images, objects, interactive visualizations,  information visualization applications, and imaginary visualizations as  in stories. While information visualization concentrates on the use of  computer-supported tools to derive new insights, knowledge visualization  focuses on transferring insights and creating new knowledge in groups.  Beyond the mere transfer of facts, knowledge visualization aims to further  transfer insights, experiences, attitudes, values, expectations, perspectives, op inions, and predictions by using various complementary visualizations.

Product visualization

Product visualization involves visualization software technology for the  viewing and manipulation of 3D models, technical drawing and other related  documentation of manufactured components and large assemblies of  products. It is a key part of product lifecycle management. Product  visualization software typically provides high levels of photorealism so that  a product can be viewed before it is actually manufactured. This supports  functions ranging from design and styling to sales and marketing. Technical

visualization is an important aspect of product development.  Originally technical drawings were made by hand, but with the rise of  advanced computer graphics the drawing board has been replaced  by computer-aided design (CAD). CAD-drawings and models have several  advantages over hand-made drawings such as the possibility of 3- D modeling, rapid prototyping, and simulation. 3D product visualization  promises more interactive experiences for online shoppers, but also  challenges retailers to overcome hurdles in the production of 3D content, as  large-scale 3D content production can be extremely costly and time- consuming.

Insight and approach

The benefits of knowledge visualization are myriad. We briefly highlighted  them earlier in this article, but in this section, we’ll go into greater depth.  This will help you have a better understanding of why you might want to  incorporate more opportunities for visualizing information into your own  organization.    For instance, knowledge visualization benefits include such things as:

1. Better Understanding – Visualizing knowledge is useful for identifying

patterns, outliers, and trends. And of course with this information,  companies can better predict where their organization, industry, or  market is headed, strategically planning for the future.

2. Improved Recall – You’re probably familiar with the saying, ―A picture

is worth a thousand words.‖ That definitely applies to knowledge  visualization. When concepts are presented to people in a visual way,  memory retention increases. As a result, knowledge visualization has  been proven to facilitate learning.

3. More Engaging – Imagine you’ve been presented with two options—

either to read a manual explaining a process flow or to actually see that  same process presented visually. If you’re like most people, you’d  probably opt for the diagram. Diagrams are usually interesting and fun  to look at. Long, boring manuals, on the other hand? Not so much.

4. Deeper Insights – Knowledge visualization shows details in context, as

well as the relationships among various objects. Because these  relationships are so clearly mapped out in graphic format, more  opportunities exist for ―a-ha‖ moments.

5. Faster Knowledge Transfer – When non-experts need to learn new

information fast, diagrams can be especially useful. Say, for instance,  that a marketing department manager needs to explain to the IT  department exactly what tasks his team performs, because he wants

marketing software to streamline their operations. Sometimes, this can  be overwhelming to try to communicate orally or even in writing.  With knowledge visualization, however, the marketing team’s  processes and workflows can be documented in such a way that the  entire IT team can quickly get up-to-speed.
