3D visualisation Techniques
Three-dimensional visualization is the ability to see, analyze and manipulate data as if it is physically present in front of you. Meteorologists have been using this technique since 1990 to compile weather forecasts and other geological data.

In the past, it was used basically for research purposes. Over the recent years, it is being used commercially and has received wide appreciation. 3D visualisation is used extensively and in many fields like science, geography, mathematics, cognition, reasoning and hypothesis building.
Uses For 3d Visualisation
When used in science, 3D visualisation is a simulation of how the research or set of hypothesis will turn out. Chemical, astrophysical and medical visualisations are common areas where 3D visualisation is used in science. Different scientific techniques like direct volume rendering and isosurface reconstruction are used to visualize different scientific studies and formulae.
In education, 3D visualisation is used on computers to show how certain things can appear. It is helpful in showing children things that are not used commonly or are not visible to the naked eye. For example, to show the atomic structure of an element and explain how the neurons, protons and electrons work together, 3D visualisation will provide a better understanding.
Product visualisation is a very prominent three-dimensional visualisation technique. This technique involves the use of computer aided design (CAD) to simulate and explore the possibilities of a structure or a program. You can view a product before it is manufactured; allowing you to alter it and change the outcome till it reaches the desired potential. CAD is used extensively when designing models for vehicles and such items.
There are many other fields that use 3D visualisation. A simple 3D picture can also explain more details as compared to a normal 2D picture. There are some very popular techniques used in 3D visualisation.
3D modeling is usually done by engineers or artists by using a modeling tool. At times, images from the real world are scanned and these engineers work on them to transform them into a physical simulation. After modeling, the image or the diagram goes through a list of animations and layouts that help it grow into a life like 3D model.
Once the model is created and all the layout and animation is added, you now render the 3D model to the required 2D image. 3D rendering can be used for games, simulations or other area where CAD is used. 3D rendering techniques vary from scanline rendering, radiosity, ray tracing to polygon-based rendering to non-realistic wireframe rendering.
When it comes to 3D visualisation techniques, 3D rendering is the most extensively used technique. Real-time rendering is used for simulations, games and other interactive media. When rendering is used for feature films and videos, it is mostly non real-time. It enables the ability to leverage limited processing power to get a better quality of the image. Obviously when an image is processed to be three-dimensional, it has to have 3D reflections and shadings. Again, there are many different techniques involved when shading and reflection is done.
