What is the process of converting a 3D scene into a 2D image called?

  1. Rasterization

  2. Ray tracing

  3. Scan conversion

  4. Rendering


Correct Option: A
Explanation:

Rasterization is the process of converting a 3D scene into a 2D image by projecting the 3D objects onto a 2D plane and then filling in the pixels of the image with the appropriate colors.

Which of the following is NOT a type of 3D transformation?

  1. Translation

  2. Rotation

  3. Scaling

  4. Projection


Correct Option: D
Explanation:

Projection is not a type of 3D transformation. It is a process of converting a 3D scene into a 2D image.

What is the process of calculating the amount of light that reaches a point on a surface called?

  1. Shading

  2. Lighting

  3. Rendering

  4. Texturing


Correct Option: B
Explanation:

Lighting is the process of calculating the amount of light that reaches a point on a surface. This information is used to determine the color of the surface.

Which of the following is NOT a type of shading?

  1. Flat shading

  2. Gouraud shading

  3. Phong shading

  4. Ambient shading


Correct Option: D
Explanation:

Ambient shading is not a type of shading. It is a global illumination technique that adds a constant amount of light to all surfaces in a scene.

What is the process of applying a texture to a surface called?

  1. Texturing

  2. Mapping

  3. Shading

  4. Lighting


Correct Option: A
Explanation:

Texturing is the process of applying a texture to a surface. This can be done using a variety of techniques, such as UV mapping and bump mapping.

Which of the following is NOT a type of texture?

  1. Diffuse texture

  2. Normal map

  3. Specular map

  4. Displacement map


Correct Option: D
Explanation:

Displacement maps are not a type of texture. They are a type of geometry map that can be used to add detail to a surface.

What is the process of creating a 3D model from a 2D image called?

  1. Photogrammetry

  2. 3D scanning

  3. Modeling

  4. Animation


Correct Option: A
Explanation:

Photogrammetry is the process of creating a 3D model from a 2D image. This can be done using a variety of techniques, such as structure from motion and multi-view stereo.

Which of the following is NOT a type of 3D scanning technology?

  1. Laser scanning

  2. Structured light scanning

  3. Photogrammetry

  4. Time-of-flight scanning


Correct Option: C
Explanation:

Photogrammetry is not a type of 3D scanning technology. It is a process of creating a 3D model from a 2D image.

What is the process of creating a 3D model from scratch called?

  1. Modeling

  2. Animation

  3. Texturing

  4. Rendering


Correct Option: A
Explanation:

Modeling is the process of creating a 3D model from scratch. This can be done using a variety of techniques, such as polygonal modeling, NURBS modeling, and subdivision surface modeling.

Which of the following is NOT a type of modeling technique?

  1. Polygonal modeling

  2. NURBS modeling

  3. Subdivision surface modeling

  4. Voxel modeling


Correct Option: D
Explanation:

Voxel modeling is not a type of modeling technique. It is a type of volumetric modeling that represents objects as a collection of voxels.

What is the process of creating a sequence of images that gives the illusion of movement called?

  1. Animation

  2. Modeling

  3. Texturing

  4. Rendering


Correct Option: A
Explanation:

Animation is the process of creating a sequence of images that gives the illusion of movement. This can be done using a variety of techniques, such as keyframe animation, motion capture, and procedural animation.

Which of the following is NOT a type of animation technique?

  1. Keyframe animation

  2. Motion capture

  3. Procedural animation

  4. Stop-motion animation


Correct Option: D
Explanation:

Stop-motion animation is not a type of animation technique. It is a technique for creating animated films by physically manipulating objects and photographing them one frame at a time.

What is the process of generating a realistic image from a 3D model called?

  1. Rendering

  2. Modeling

  3. Texturing

  4. Animation


Correct Option: A
Explanation:

Rendering is the process of generating a realistic image from a 3D model. This can be done using a variety of techniques, such as ray tracing, rasterization, and scanline rendering.

Which of the following is NOT a type of rendering technique?

  1. Ray tracing

  2. Rasterization

  3. Scanline rendering

  4. Phong shading


Correct Option: D
Explanation:

Phong shading is not a type of rendering technique. It is a type of shading technique that is used to calculate the amount of light that reaches a point on a surface.

What is the process of adding realism to a 3D model by adding details such as dirt, scratches, and wear and tear called?

  1. Texturing

  2. Modeling

  3. Animation

  4. Rendering


Correct Option: A
Explanation:

Texturing is the process of adding realism to a 3D model by adding details such as dirt, scratches, and wear and tear. This can be done using a variety of techniques, such as UV mapping and bump mapping.
