Question

An old set of 2D animated cartoons from the 1940s has been discovered and it is decided to modify them to turn them into 3D animation.

Define the term visualization.

[1]

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

[2]

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

[6]

Markscheme

The creation of a human interpretable image from data;

Award [2 max].
The characters are defined as mathematical models;
They will need rendering to give a 3D effect;
Each movement will need to be fluid;
The animation is less interesting with flat figures;

Allow mark for explanation of rendering.

Award [6 max].
Rendering for non-interactive media such as animations is a much slower process than for interactive media/games;
Rendering times for individual frames may vary from a few seconds to days depending on the complexity of the scene;
Rendered frames are stored to a hard disk and then transferred to other media for playback;
3D rendering is computationally resource hungry;
Computer processing power has increased rapidly and greatly over the years;
Allowing a much higher degree of photorealism / realistic rendering;

Examiners report

The question was reasonably well answered by majority of the candidates.

Most answers tended to be superficial and generic in nature. The responses were mostly focused on a description of rendering rather than why it was important in the process.

Most candidates focused on explaining the process of rendering and creating 3D animation rather than technical implications of doing so.
