  1. LOD (Level of Detail)

  2. Texture streaming

  3. Culling

  4. All of the above
Reveal answer Fill a bubble to check yourself
Correct answer
Explanation

Optimizing game graphics for real-time rendering involves techniques such as LOD (Level of Detail) to adjust the detail level of objects based on their distance from the camera, texture streaming to load textures on-demand, and culling to remove objects that are not visible to the player.

Multiple choice

What is the term used to describe the technique of using real-world photographs or scans as a basis for creating game textures?

  1. Photogrammetry

  2. Procedural texturing

  3. Hand-painted textures

  4. Normal mapping
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Photogrammetry is the technique of using real-world photographs or scans to create realistic textures for game objects. This involves capturing high-resolution images of real-world objects and converting them into digital textures.

Multiple choice

Which of the following is a common technique used to create realistic facial animations in photorealistic game characters?

  1. Motion capture

  2. Keyframe animation

  3. Procedural animation

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Motion capture is a common technique used to create realistic facial animations in photorealistic game characters. It involves recording the facial movements of real actors using specialized equipment and transferring the data to the game characters.

Multiple choice

What is the term used to describe the technique of simulating the scattering of light beneath a surface, resulting in a more realistic appearance?

  1. Subsurface scattering

  2. Ambient occlusion

  3. Ray tracing

  4. Global illumination
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Subsurface scattering is a technique used to simulate the scattering of light beneath a surface, resulting in a more realistic appearance. This is particularly important for materials like skin, which allows light to penetrate and scatter within the material.

Multiple choice
