Animation and Visual Effects Questions

Multiple choice

Which of the following is not a common technique for improving the performance of a graphics pipeline?

  1. Using a more powerful graphics card

  2. Reducing the resolution of the rendered image

  3. Using a lower level of detail for objects that are far away

  4. Using a higher level of detail for objects that are close to the viewer
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Using a higher level of detail for objects that are close to the viewer can actually decrease performance, as the graphics card needs to process more data for each object. The other options are all common techniques for improving the performance of a graphics pipeline.
