  1. Random rotation

  2. Random translation

  3. Random scaling

  4. All of the above

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

Random rotation, random translation, and random scaling are all data augmentation techniques used for point cloud data. They help create variations in the training data by rotating, translating, and scaling the point clouds.

Multiple choice

Which of the following is NOT a potential application of GANs in video games?

  1. Creating realistic character models

  2. Generating new levels and environments

  3. Creating realistic animations

  4. Replacing traditional game artists

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

GANs are not likely to replace traditional game artists, as they are still a relatively new technology and they are not yet able to create the same level of detail and creativity as human artists.

Multiple choice

Which image processing technique is commonly used to create realistic textures for 3D models in games?

  1. Edge Detection

  2. Color Quantization

  3. Bump Mapping

  4. Image Segmentation

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

Bump mapping is a technique used to add detail and texture to 3D models by simulating the way light interacts with a surface. It involves creating a normal map, which is a grayscale image that encodes the surface normals of the object.

Multiple choice

Which image processing technique is used to create realistic shadows in games?

  1. Ray Tracing

  2. Ambient Occlusion

  3. Phong Shading

  4. Cel Shading

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

Ambient occlusion is a technique used to simulate the way light is blocked by objects in a scene, creating realistic shadows and enhancing the overall realism of the game environment.

Multiple choice

Which image processing technique is commonly used to create special effects in movies and games?

  1. Motion Blur

  2. Depth of Field

  3. Lens Flare

  4. All of the above

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

Motion blur, depth of field, and lens flare are all image processing techniques commonly used to create special effects in movies and games. Motion blur simulates the effect of camera movement, depth of field creates a sense of focus, and lens flare adds a realistic glare effect to light sources.

Multiple choice

Which image processing technique is used to create realistic facial animations in games?

  2. Facial Recognition

  3. Shape Interpolation

  4. Blendshape Animation

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

Blendshape animation is a technique used to create realistic facial animations in games by blending different facial expressions together. It involves creating a series of key poses, or blendshapes, and then interpolating between them to create smooth and natural animations.
