3D Art 1: Modeling Unit 2 Test Review

What is another term for surface models?

• shell models 

• wire models 

• solid models 

• pseudo models S

Which of the following 3D modeling techniques uses complex mathematical formulas to calculate surfaces and create a series of interwoven lines to illustrate the contours of objects? 

• parametric 3D modeling 

• NURBS modeling 

• digital sculpting 

• polygon modeling 

This process makes the 3D model look more alive, as attention is given to every detail and making everything more precise. 

• Detailing 

• Texturing 

• Rendering 

• Blocking 

Which of the following stages are part of the pre-production stage of the 3D modeling production workflow? 

• rendering and adjusting of the lights of the 3D project 

• selecting the type of 3D modeling to be used 

• creating a style guide to maintain consistency across the 3D model 

• arranging primitive 3D shapes to give a body that looks closer to the desired output 

 What is the first step involved in the production stage of a 3D modeling production workflow. 

• building a 3D layout (Proxy Model)

• creating a 3D model 

• Apply texture 

In this process, a rough model of the 3D object is made in the first step and arranged into a scene by the artist. The object's structure and boundary are then analyzed. 

• Detailing 

• Texturing 

• Rendering 

• Blocking 

In this process, detail is added to the initial 3D model blocks, so that they look smoother and closer to their final shape. 

• Detailing 

• Texturing 

• Rendering 

• Blocking 

In this process, the model is made to appear more realistic by adding colors, designs, and textures. 

• Detailing 

• Texturing 

• Rendering 

• Blocking 

Which of the following models has no surfaces? 

• wireframe model 

• solid model 

• polygonal model 

• surface model 

Answer explanation

A wireframe model is a skeletal description of a 3D object. There are no surfaces in a wireframe model. 

Which of the following 3D modeling techniques is used to represent the outside complex structures of an aircraft body? 

• wireframe modeling 

• surface modeling 

• isometric modeling 

Answer explanation

For complex objects, 3D modeling can be achieved by surface modeling as it has more number of vertices and can also design curves.
