Photography and Graphics Questions

Multiple choice

What is the purpose of environment mapping?

  1. To simulate the effect of light bouncing off multiple surfaces in a scene

  2. To create the illusion of a reflective surface

  3. To add detail to the surface of an object without increasing the number of polygons

  4. To generate shadows from point light sources
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Environment mapping is a technique used to create the illusion of a reflective surface. This is done by storing the environment map in a texture map, which is then used to calculate the reflection of the environment on the surface of the object.

Multiple choice

What is the purpose of light probes?

  1. To store information about the lighting in a scene

  2. To generate shadows from point light sources

  3. To create the illusion of a reflective surface

  4. To add detail to the surface of an object without increasing the number of polygons
