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

Graph isomorphism is used in a variety of applications in computer graphics, including 3D modeling, animation, and rendering. In 3D modeling, graph isomorphism is used to create 3D models of objects. In animation, graph isomorphism is used to create animations of objects. In rendering, graph isomorphism is used to generate images of objects.

Multiple choice

Which technology is often used to create digital models of folk dancers' movements?

  1. Motion capture systems

  2. 3D scanning

  3. Computer animation

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

Motion capture systems are often used to create digital models of folk dancers' movements. These systems use sensors to track the movements of the dancers' bodies, and then use this data to create a digital model of the dance.
