3D Representations

What is the primary function of a wireframe in 3D modeling?

• To add colors to a model

• To provide a skeletal representation of the geometry of the model

• To create animated sequences

• To texture the model

Which of the following is NOT a standard method of 3D modeling?

• Box modeling

• NURBS modeling

• Vector modeling

• Polygon modeling

In 3D modeling, what is 'texturing'?

• Removing unwanted polygons

• Applying images or patterns to the surface of a 3D object

• Adjusting the light settings

• Sculpting details on a 3D model

Which file format is commonly used to exchange 3D model data between different software?

• JPEG

• OBJ

• TXT

• MP4

What does the term "rendering" refer to in 3D modeling?

• The process of creating 2D images from a 3D model

• The process of deleting parts of a model

• The method of making a model interactive

• The animation of a model

What is a normal map used for in 3D modeling?

• To simulate the high-resolution details on a lower-resolution model

• To increase the polygon count of a model

• To reduce rendering time

Which 3D modeling software is known for its robust feature set and wide use in the film industry?

• Adobe Photoshop

What does UV mapping help with in the context of 3D modeling?

• Removing polygons from a model

• Unwrapping a 3D model to a 2D texture

Which technique would you typically use to create a human face in 3D modeling?

• Boolean modeling

• Spline modeling

• Subdivision surface modeling

• Solid geometry

What role does subdivision play in 3D modeling?

• It decreases the number of polygons in a mesh.

• It is used to animate models.

• It increases the detail and smoothness of a mesh.

• It extracts texture maps from a model.
