What is the process of applying a texture to a 3D model called?

  1. Texturing

  2. Mapping

  3. Shading

  4. Rendering


Correct Option: A
Explanation:

Texturing is the process of applying a texture to a 3D model to add detail and realism.

Which of the following is a common type of texture map?

  1. Diffuse map

  2. Normal map

  3. Specular map

  4. All of the above


Correct Option: D
Explanation:

Diffuse map, normal map, and specular map are all common types of texture maps used in computer graphics.

What is the purpose of a diffuse map?

  1. To define the color of a surface

  2. To define the surface's roughness

  3. To define the surface's reflectivity

  4. To define the surface's normal vectors


Correct Option: A
Explanation:

A diffuse map defines the color of a surface by specifying the RGB values at each pixel.

What is the purpose of a normal map?

  1. To define the color of a surface

  2. To define the surface's roughness

  3. To define the surface's reflectivity

  4. To define the surface's normal vectors


Correct Option: D
Explanation:

A normal map defines the surface's normal vectors at each pixel, which can be used to simulate surface detail and shading.

What is the purpose of a specular map?

  1. To define the color of a surface

  2. To define the surface's roughness

  3. To define the surface's reflectivity

  4. To define the surface's normal vectors


Correct Option: C
Explanation:

A specular map defines the surface's reflectivity at each pixel, which can be used to simulate the way light reflects off the surface.

Which mapping technique is commonly used to apply a texture to a cylindrical object?

  1. Cylindrical mapping

  2. Spherical mapping

  3. Planar mapping

  4. Cube mapping


Correct Option: A
Explanation:

Cylindrical mapping is commonly used to apply a texture to a cylindrical object because it preserves the proportions of the texture.

Which mapping technique is commonly used to apply a texture to a spherical object?

  1. Cylindrical mapping

  2. Spherical mapping

  3. Planar mapping

  4. Cube mapping


Correct Option: B
Explanation:

Spherical mapping is commonly used to apply a texture to a spherical object because it minimizes distortion.

Which mapping technique is commonly used to apply a texture to a flat surface?

  1. Cylindrical mapping

  2. Spherical mapping

  3. Planar mapping

  4. Cube mapping


Correct Option: C
Explanation:

Planar mapping is commonly used to apply a texture to a flat surface because it is simple and efficient.

Which mapping technique is commonly used to apply a texture to a cube-shaped object?

  1. Cylindrical mapping

  2. Spherical mapping

  3. Planar mapping

  4. Cube mapping


Correct Option: D
Explanation:

Cube mapping is commonly used to apply a texture to a cube-shaped object because it allows for seamless transitions between the different faces of the cube.

What is the main advantage of using mipmaps?

  1. Improved performance

  2. Reduced memory usage

  3. Increased texture quality

  4. All of the above


Correct Option: D
Explanation:

Mipmaps offer improved performance, reduced memory usage, and increased texture quality.

What is the purpose of anisotropic filtering?

  1. To improve the quality of textures when viewed at an angle

  2. To reduce aliasing in textures

  3. To increase the performance of texture filtering

  4. All of the above


Correct Option: A
Explanation:

Anisotropic filtering improves the quality of textures when viewed at an angle by reducing the amount of blur.

What is the main disadvantage of using bump mapping?

  1. Increased computational cost

  2. Reduced texture quality

  3. Increased memory usage

  4. All of the above


Correct Option: A
Explanation:

Bump mapping's main disadvantage is its increased computational cost, as it requires additional calculations to simulate the surface detail.

Which of the following is not a common type of procedural texture?

  1. Perlin noise

  2. Fractal noise

  3. Voronoi noise

  4. Image-based texture


Correct Option: D
Explanation:

Image-based textures are not procedural textures, as they are created from images rather than generated algorithmically.

What is the main advantage of using procedural textures?

  1. Increased computational cost

  2. Reduced memory usage

  3. Increased texture quality

  4. All of the above


Correct Option: B
Explanation:

Procedural textures offer reduced memory usage compared to image-based textures, as they are generated algorithmically and do not require storing large image files.

Which of the following is not a common application of texturing and mapping in computer graphics?

  1. Video games

  2. 3D modeling

  3. Animation

  4. Web design


Correct Option: D
Explanation:

Texturing and mapping are primarily used in 3D graphics applications such as video games, 3D modeling, and animation, rather than web design.
