Frequently Asked Questions In Interview On Scientific Visualization

Q – 1 Tell me about visualization?

Ans- 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 man.

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.

Q – 2 What is scientific visualization?

Ans- Scientific visualization =also spelled scientific visualisation is an interdisciplinary branch of science and primarily concerned with the visualization of three-dimensional phenomena (architectural, meteorological, medical, biological, etc.), where the emphasis is on realistic renderings of volumes, surfaces, illumination sources, and so forth, perhaps with a dynamic (time) component

Q – 3 What is information visualization?

Ans- Information visualization or information visualisation is the study of interactive visual representations of abstract data to reinforce human cognition. The abstract data include both numerical and non-numerical data, such as text and geographic information. However, information visualization differs from scientific visualization

Q – 4 What is volume visualization?

Ans- volume visualization examines a set of techniques that allows viewing an object without mathematically representing the other surface. Initially used in medical imaging, volume visualization has become an essential technique for many sciences, portraying phenomena become an essential technique such as clouds, water flows, and molecular and biological structure.

Many volume visualization algorithms are computationally expensive and demand large data storage. Advances in hardware and software are generalizing volume visualization as well as real time performances

Q – 5 What is ray casting?

Ans- Ray casting is the use of ray-surface intersection tests to solve a variety of problems in computer graphics.

Q – 6 What is a Histogram?

Ans- Histogram is a graphical representation of the distribution of data. It is an estimate of the probability distribution of a continuous variable
