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

  1. Texturing

  2. Mapping

  3. Rendering

  4. Shading


Correct Option: A
Explanation:

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

Which of the following is not a common texture mapping technique?

  1. UV Mapping

  2. Bump Mapping

  3. Displacement Mapping

  4. Parallax Mapping


Correct Option: D
Explanation:

Parallax Mapping is not a common texture mapping technique. It is a more advanced technique that simulates the displacement of the surface based on the angle of the viewer.

What is the purpose of UV Mapping?

  1. To assign textures to a 3D model

  2. To create a normal map

  3. To generate a displacement map

  4. To calculate the lighting on a surface


Correct Option: A
Explanation:

UV Mapping is used to assign textures to a 3D model by defining the relationship between the texture coordinates and the model's surface.

Which of the following is not a type of texture filter?

  1. Bilinear Filtering

  2. Trilinear Filtering

  3. Anisotropic Filtering

  4. Mipmapping


Correct Option: D
Explanation:

Mipmapping is not a texture filter. It is a technique used to reduce texture aliasing by generating multiple levels of detail for a texture.

What is the purpose of bump mapping?

  1. To add detail to a texture

  2. To simulate surface displacement

  3. To create a normal map

  4. To generate a specular map


Correct Option: B
Explanation:

Bump mapping is used to simulate surface displacement by adding detail to a texture without actually changing the geometry of the model.

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

  1. Perlin Noise

  2. Voronoi Texture

  3. Fractal Noise

  4. Marble Texture


Correct Option: D
Explanation:

Marble Texture is not a type of procedural texture. It is a specific type of texture that is used to create a marble-like appearance.

What is the purpose of a normal map?

  1. To add detail to a texture

  2. To simulate surface displacement

  3. To create a specular map

  4. To store the surface normals of a model


Correct Option: D
Explanation:

A normal map is used to store the surface normals of a model, which allows for more realistic lighting and shading.

Which of the following is not a type of texture projection?

  1. Cylindrical Projection

  2. Spherical Projection

  3. Planar Projection

  4. Cubemap Projection


Correct Option: C
Explanation:

Planar Projection is not a type of texture projection. It is a type of camera projection that is used in orthographic cameras.

What is the purpose of a displacement map?

  1. To add detail to a texture

  2. To simulate surface displacement

  3. To create a normal map

  4. To generate a specular map


Correct Option: B
Explanation:

A displacement map is used to simulate surface displacement by actually changing the geometry of the model.

Which of the following is not a type of texture wrap mode?

  1. Repeat

  2. Clamp

  3. Mirror

  4. Border


Correct Option: D
Explanation:

Border is not a type of texture wrap mode. It is a type of texture filter that is used to handle textures that are smaller than the surface they are being applied to.

What is the purpose of a specular map?

  1. To add detail to a texture

  2. To simulate surface displacement

  3. To create a normal map

  4. To control the specular highlights on a surface


Correct Option: D
Explanation:

A specular map is used to control the specular highlights on a surface, which allows for more realistic rendering of materials.

Which of the following is not a type of texture format?

  1. JPEG

  2. PNG

  3. TGA

  4. DDS


Correct Option: D
Explanation:

DDS is not a type of texture format. It is a specific texture format that is commonly used in video games.

What is the purpose of anisotropic filtering?

  1. To reduce texture aliasing

  2. To improve texture detail

  3. To optimize texture performance

  4. To reduce texture shimmering


Correct Option: D
Explanation:

Anisotropic filtering is used to reduce texture shimmering, which is a type of aliasing that occurs when textures are viewed at an angle.

Which of the following is not a type of texture blending mode?

  1. Add

  2. Multiply

  3. Subtract

  4. Overlay


Correct Option: D
Explanation:

Overlay is not a type of texture blending mode. It is a type of layer blending mode that is used in image editing software.

What is the purpose of a texture atlas?

  1. To combine multiple textures into a single file

  2. To reduce texture memory usage

  3. To improve texture performance

  4. To optimize texture loading


Correct Option: A
Explanation:

A texture atlas is used to combine multiple textures into a single file, which can reduce texture memory usage and improve texture performance.
