Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A Sankey diagram is a visualization technique that represents the flow of data between different entities or processes, with the width of the arrows proportional to the amount of data flowing.

Multiple choice

Which shading model is commonly used in real-time rendering due to its computational efficiency?

  1. Phong Shading

  2. Blinn-Phong Shading

  3. Cook-Torrance Shading

  4. Lambert Shading
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Phong shading is a popular shading model that approximates the appearance of curved surfaces by interpolating normal vectors and calculating the diffuse and specular components of light reflection.

Multiple choice

Which shading model is known for its ability to simulate complex materials like metals and plastics?

  1. Phong Shading

  2. Blinn-Phong Shading

  3. Cook-Torrance Shading

  4. Lambert Shading
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cook-Torrance shading is capable of simulating complex materials like metals and plastics by accurately modeling the reflection of light from microfacets on the surface.

Multiple choice

Which of the following is not a common technique for reducing the number of polygons that need to be rendered?

  1. Back-face culling

  2. Frustum culling

  3. Occlusion culling

  4. Tessellation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tessellation is a technique for increasing the number of polygons in a scene, not reducing it. The other options are all common techniques for reducing the number of polygons that need to be rendered.

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.
