Three-dimensional use of visualization

Modeling & Simulation

In general there is a correlation between the size of the data you are visualizing and the amount of memory required to efficiently process and create the visualization. In addition, consider graphics car memory to graphically render the actual visualization.

Some test questions and answers

• Outline a situation where 2D visualization would be more appropriate than 3D visualization.
  • For example, a map showing the journey from one point to another;
  • When only the route needs to be shown on a phone or otherwise;
  • As 3D version could take up too much space;
  • If no internet connection would be too slow;

An artist is planning to create a statue, but decides to do some planning before she starts.

• Outline the advantages, to the artist, of using a computer aided design (CAD) and graphic processing software for 3D modelling, instead of a series of sketches drawn by

hand, to experiment with designs. [3]

• • A series of sketches could show the design from a limited number of angles; Whereas the CAD system would allow an initial wire frame to be constructed which could be rotated;
  • Changes could be (easily) made and the effect of the 3D shape from other angles seen immediately;
  • Easy to undo a change to the model, rather than erase part of the sketch;
  • Easy to scale the design;
  • CAD files are less likely to get damaged than physical drawings;
  • Note: Do not accept vague statements like “CAD is more precise”.

• Outline the basic steps used in the process of rendering to give a 3D visualization of the final proposed statue.

• • Rendering would take place;
  • To apply light and texture to the model;
  • Using such techniques as ray tracing;
  • To the (wireframe) 2D representation;
  • To produce a realistic view of the final product in the chosen material;

Standards

• Identify a three-dimensional use of visualization.

Give a brief account.

Produce a plan, simulation or model.

A unit of abstract mathematical system subject to the laws of arithmetic.

Represent by means of a diagram or graph (labelled as appropriate). The sketch should give a general idea of the required shape or relationship, and should include relevant features.

Use an idea, equation, principle, theory or law in relation to a given problem or issue.

Provide an answer from a number of possibilities. Recognize and state briefly a distinguishing fact or feature.
