What is the primary purpose of visual effects in game graphics?

  1. To make the game look realistic

  2. To enhance the player's immersion

  3. To create a visually appealing experience

  4. All of the above

Show answer
Correct Option: D
Explanation:

Visual effects in game graphics serve multiple purposes, including making the game look realistic, enhancing the player's immersion, and creating a visually appealing experience.

Which of the following is NOT a common type of visual effect used in game graphics?

  1. Particle effects

  2. Lighting effects

  3. Post-processing effects

  4. Motion capture

Show answer
Correct Option: D
Explanation:

Motion capture is a technique used to record the movements of actors and animate characters in games. It is not a visual effect in the same way that particle effects, lighting effects, and post-processing effects are.

What is the difference between a particle effect and a lighting effect?

  1. Particle effects are animated objects, while lighting effects are static

  2. Particle effects are used to create explosions and other dynamic effects, while lighting effects are used to create shadows and highlights

  3. Particle effects are typically more computationally expensive than lighting effects

  4. All of the above

Show answer
Correct Option: D
Explanation:

Particle effects are animated objects that can be used to create explosions, fire, smoke, and other dynamic effects. Lighting effects are used to create shadows, highlights, and other effects that add depth and realism to a scene. Particle effects are typically more computationally expensive than lighting effects.

What is post-processing?

  1. A technique used to apply additional effects to a rendered image

  2. A technique used to optimize the performance of a game

  3. A technique used to create realistic physics simulations

  4. A technique used to generate procedural textures

Show answer
Correct Option: A
Explanation:

Post-processing is a technique used to apply additional effects to a rendered image, such as color correction, bloom, and depth of field.

Which of the following is NOT a common post-processing effect?

  1. Motion blur

  2. Anti-aliasing

  3. Tessellation

  4. High dynamic range (HDR)

Show answer
Correct Option: C
Explanation:

Tessellation is a technique used to increase the detail of a mesh by dividing it into smaller triangles. It is not a post-processing effect.

What is the difference between real-time rendering and pre-rendered graphics?

  1. Real-time rendering is used for games, while pre-rendered graphics are used for movies

  2. Real-time rendering is more computationally expensive than pre-rendered graphics

  3. Real-time rendering allows for more dynamic and interactive scenes

  4. All of the above

Show answer
Correct Option: D
Explanation:

Real-time rendering is used for games and other interactive applications, while pre-rendered graphics are used for movies and other non-interactive media. Real-time rendering is more computationally expensive than pre-rendered graphics, but it allows for more dynamic and interactive scenes.

Which of the following is NOT a common real-time rendering technique?

  1. Rasterization

  2. Ray tracing

  3. Voxel-based rendering

  4. Scanline rendering

Show answer
Correct Option: D
Explanation:

Scanline rendering is an older rendering technique that is no longer commonly used in real-time graphics. Rasterization, ray tracing, and voxel-based rendering are all common real-time rendering techniques.

What is the difference between a vertex shader and a fragment shader?

  1. Vertex shaders are used to transform vertices, while fragment shaders are used to color pixels

  2. Vertex shaders are used to calculate lighting, while fragment shaders are used to apply textures

  3. Vertex shaders are executed once per vertex, while fragment shaders are executed once per pixel

  4. All of the above

Show answer
Correct Option: D
Explanation:

Vertex shaders are used to transform vertices, calculate lighting, and apply textures. Fragment shaders are used to color pixels.

What is a normal map?

  1. A texture that stores the surface normals of a mesh

  2. A texture that stores the heightmap of a mesh

  3. A texture that stores the color of a mesh

  4. A texture that stores the opacity of a mesh

Show answer
Correct Option: A
Explanation:

A normal map is a texture that stores the surface normals of a mesh. This information can be used to improve the realism of lighting and shading.

What is a parallax occlusion map?

  1. A texture that stores the depth of a mesh

  2. A texture that stores the surface normals of a mesh

  3. A texture that stores the color of a mesh

  4. A texture that stores the opacity of a mesh

Show answer
Correct Option: A
Explanation:

A parallax occlusion map is a texture that stores the depth of a mesh. This information can be used to create the illusion of depth and detail in a surface.

What is a cube map?

  1. A texture that stores the environment around a point

  2. A texture that stores the surface normals of a mesh

  3. A texture that stores the heightmap of a mesh

  4. A texture that stores the color of a mesh

Show answer
Correct Option: A
Explanation:

A cube map is a texture that stores the environment around a point. This information can be used to create realistic reflections and lighting effects.

What is a lightmap?

  1. A texture that stores the lighting information for a scene

  2. A texture that stores the surface normals of a mesh

  3. A texture that stores the heightmap of a mesh

  4. A texture that stores the color of a mesh

Show answer
Correct Option: A
Explanation:

A lightmap is a texture that stores the lighting information for a scene. This information can be used to improve the performance of a game by pre-calculating the lighting.

What is a shadow map?

  1. A texture that stores the shadows in a scene

  2. A texture that stores the surface normals of a mesh

  3. A texture that stores the heightmap of a mesh

  4. A texture that stores the color of a mesh

Show answer
Correct Option: A
Explanation:

A shadow map is a texture that stores the shadows in a scene. This information can be used to create realistic shadows in a game.

What is a motion blur effect?

  1. An effect that blurs the image to simulate motion

  2. An effect that sharpens the image to improve clarity

  3. An effect that adds a glow to the image to make it look more vibrant

  4. An effect that reduces the color saturation of the image to make it look more muted

Show answer
Correct Option: A
Explanation:

A motion blur effect is an effect that blurs the image to simulate motion. This can be used to create a sense of speed or to smooth out the animation.

What is a depth of field effect?

  1. An effect that blurs the background of an image to focus on the foreground

  2. An effect that sharpens the image to improve clarity

  3. An effect that adds a glow to the image to make it look more vibrant

  4. An effect that reduces the color saturation of the image to make it look more muted

Show answer
Correct Option: A
Explanation:

A depth of field effect is an effect that blurs the background of an image to focus on the foreground. This can be used to create a sense of depth and realism.
