Outline the need for rendering in the creation of the animated 3D characters.

Explain two technical implications of implementing a 3D animation in this way.

With the help of examples, discuss how the development in the way such data is visualized has made the results of these simulations more accessible to the general public.

Define the term visualization.

Define the term visualization.

The medical school is considering updating its simulation software, which currently displays the simulation in 2D, to one that displays it in 3D.

Discuss whether this change to a 3D display would improve the quality of the training.

Explain why the development of a visualization model was necessary in this scenario.

Identify four items of data that would be included to create the 2D visualization model.

Explain why a 2D visualization model would be used rather than a 3D visualization model in this scenario.

Define the term visualization.

Identify how a 2D visualization could be used in this scenario.

Explain the benefits of using visualization when simulating rising sea levels.

Once the 3D visualization has been rendered, when the user drags a slider bar to simulate the amount of ice that has melted, the visualization is re-rendered without any delay.

Vehicles are tested for their exhaust gas emissions using simulation software at specialist garages. During a period of 5 minutes, a vehicle with the engine switched on is monitored for emissions of carbon dioxide (CO₂) and fine particulates. The software uses 3D visualization techniques to display these parameters on a screen for the whole duration of the test.

Explain how emissions of CO₂ and fine particulates could be represented in 3D by the software.
