Which of the following is NOT a common 3D modeling software?

  1. Blender

  2. Maya

  3. ZBrush

  4. Adobe Photoshop


Correct Option: D
Explanation:

Adobe Photoshop is a raster graphics editor, primarily used for image editing and manipulation, not for 3D modeling.

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

  1. Photogrammetry

  2. 3D Scanning

  3. Digital Painting

  4. Texturing


Correct Option: A
Explanation:

Photogrammetry is the process of creating a 3D model from a series of 2D photographs.

Which animation technique involves manipulating the position, rotation, and scale of an object over time?

  1. Keyframe Animation

  2. Motion Capture

  3. Procedural Animation

  4. Stop-Motion Animation


Correct Option: A
Explanation:

Keyframe animation involves setting keyframes at specific points in time and interpolating the animation between those keyframes.

What is the process of adding textures, materials, and lighting to a 3D model called?

  1. Texturing

  2. Shading

  3. Rendering

  4. Rigging


Correct Option: A
Explanation:

Texturing involves applying textures to the surface of a 3D model to add detail and realism.

Which of the following is NOT a common 3D animation technique?

  1. Keyframe Animation

  2. Motion Capture

  3. Procedural Animation

  4. Rotoscoping


Correct Option: D
Explanation:

Rotoscoping is a technique used in 2D animation, not 3D animation.

What is the process of creating a skeleton and attaching it to a 3D model to enable animation called?

  1. Rigging

  2. Skinning

  3. Weight Painting

  4. Morphing


Correct Option: A
Explanation:

Rigging involves creating a skeleton and attaching it to a 3D model, allowing animators to control the movement of the model.

Which of the following is NOT a common 3D modeling primitive?

  1. Cube

  2. Sphere

  3. Cylinder

  4. Torus


Correct Option: D
Explanation:

Torus is not a common 3D modeling primitive, unlike cube, sphere, and cylinder.

What is the process of simulating the physical properties of objects in a 3D scene called?

  1. Physics Simulation

  2. Collision Detection

  3. Fluid Simulation

  4. Particle Simulation


Correct Option: A
Explanation:

Physics simulation involves simulating the physical properties of objects in a 3D scene, such as gravity, collisions, and fluid dynamics.

Which of the following is NOT a common 3D modeling technique?

  1. Polygonal Modeling

  2. NURBS Modeling

  3. Voxel Modeling

  4. Digital Sculpting


Correct Option: D
Explanation:

Digital sculpting is not a common 3D modeling technique, unlike polygonal modeling, NURBS modeling, and voxel modeling.

What is the process of creating a 3D model from a series of 2D cross-sections called?

  1. Lathe Modeling

  2. Loft Modeling

  3. Sweep Modeling

  4. Bevel Modeling


Correct Option: B
Explanation:

Loft modeling involves creating a 3D model from a series of 2D cross-sections.

Which of the following is NOT a common 3D animation software?

  1. Maya

  2. 3ds Max

  3. Blender

  4. Adobe After Effects


Correct Option: D
Explanation:

Adobe After Effects is a compositing and motion graphics software, not primarily used for 3D animation.

What is the process of creating a 3D model from a point cloud generated by a 3D scanner called?

  1. Photogrammetry

  2. 3D Scanning

  3. Mesh Generation

  4. Reverse Engineering


Correct Option: C
Explanation:

Mesh generation involves creating a 3D model from a point cloud generated by a 3D scanner.

Which of the following is NOT a common 3D modeling file format?

  1. OBJ

  2. FBX

  3. STL

  4. JPEG


Correct Option: D
Explanation:

JPEG is an image file format, not a 3D modeling file format.

What is the process of creating a 3D model from a series of mathematical equations called?

  1. Procedural Modeling

  2. Parametric Modeling

  3. Implicit Modeling

  4. Constructive Solid Geometry


Correct Option: A
Explanation:

Procedural modeling involves creating a 3D model from a series of mathematical equations.

Which of the following is NOT a common 3D 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 common 3D animation technique, unlike keyframe animation, motion capture, and procedural animation.
