3D FA6

QuestionAnswer
Ambient occlusion occurs when indirect light rays are prevented from reaching a surface. Ambient occlusion is a soft and subtle type of shadowing. It’s usually found in the cracks and crevices Choices: T or F True
Using raytrace shadows produces more accurate results, but it often takes a little more time and processor power to calculate. Choices: True False True
This effect describes the amount of reflection and refraction that occurs on a surface as the viewing angle changes. Choices: Anisotropy Refraction Diffusion Fresnel Effect Fresnel Effect
This is the region of sharp focus in a photograph. Choices: Depth of field Ambient Aperture Exposure Depth of field
A transparent surface can change the direction of the light rays as they pass through the surface. The bending of light rays can distort the image of objects on the other side of the surface Choices: Diffusion Reflection Refraction Fresnel Effect Refraction
With a 3D texture, objects appear to be carved out of a substance, such as rock or wood. You can scale, rotate and move 3D textures interactively in a scene view to achieve the desired results. Choices: True False True
Layering shaders are considered physical-based shaders. Therefore, they should interact only with lights that are physically plausible; that is, the light should act like a realworld light Choices: True False true
describes how a light ray is reflected off a rough surface. Choices: Diffusion Reflection Fresnel Effect Refraction Diffusion
Area lights and image-based lighting work best with the layering shaders, since their visible light corresponds with the light that they actually cast. Choices: True False true
Cast shadows are created when an object blocks the rays of light coming from a light source. Choices: true or false true

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
