Multiple choice

What is the name of the algorithm used to generate shadows in computer graphics?

  1. Ray tracing

  2. Z-buffering

  3. Shadow mapping

  4. Stencil buffering
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Shadow mapping is an algorithm used to generate shadows in computer graphics. It works by projecting the scene from the light source's point of view and storing the resulting depth values in a texture map. This texture map is then used to determine which parts of the scene are in shadow.

Multiple choice

Which transformation matrix is used to translate an object in 3D space?

  1. Translation matrix

  2. Rotation matrix

  3. Scaling matrix

  4. Shear matrix
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The translation matrix is used to translate an object in 3D space. It is a 4x4 matrix that contains the x, y, and z translation values in the first three columns and the fourth column is set to (0, 0, 0, 1).

Multiple choice

Which algorithm is used to generate realistic reflections in computer graphics?

  1. Ray tracing

  2. Z-buffering

  3. Shadow mapping

  4. Stencil buffering
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ray tracing is an algorithm used to generate realistic reflections in computer graphics. It works by simulating the path of light rays as they bounce off surfaces in a scene. This allows for accurate and detailed reflections, but it can be computationally expensive.

Multiple choice

What is the name of the technique used to create the illusion of depth in a 2D image?

  1. Perspective projection

  2. Orthographic projection

  3. Isometric projection

  4. Oblique projection
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Perspective projection is a technique used to create the illusion of depth in a 2D image. It works by projecting the scene onto a plane that is not parallel to the objects in the scene. This causes objects that are closer to the camera to appear larger than objects that are farther away.

Multiple choice

Which algorithm is used to generate realistic motion blur in computer graphics?

  1. Ray tracing

  2. Z-buffering

  3. Shadow mapping

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

Motion blur is an algorithm used to generate realistic motion blur in computer graphics. It works by simulating the effect of a moving camera on the image. This can be used to create a sense of speed or movement in a scene.

Multiple choice

What is the name of the technique used to create realistic textures for 3D models?

  1. Bump mapping

  2. Normal mapping

  3. Parallax mapping

  4. Displacement mapping
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Normal mapping is a technique used to create realistic textures for 3D models. It works by storing the normal vectors of the surface at each pixel in a texture map. This information can then be used to simulate the way light interacts with the surface, resulting in a more realistic appearance.
