Choose the correct definition for Topology. (3D Modeling)
Topology refers to basic shapes such as sphere, cube, cone, cylinder, torus, and plane.
This refers to the geometric surface characteristics of a 3D object. Topology consist of faces, edges, and vertices. Faces are usually quadrilateral or triangular, and make up the surface of the 3D model.
Topology is a modeling technique that allows the modeller to create 3D characthers usimg NURBS curves.
What is the main difference between Photorealistic and Stylized 3D models?
Stylized models tend to have exaggerated features that appear cartoony while Photorealistic modeling aims to simulate eye-for-eye a 3D object that looks exactly like the real-world object.
Photorealistic models tend to have exaggerated features that appear cartoony while Stylized modeling aims to simulate eye-for-eye a 3D object that looks exactly like the real-world object.
Both stylized and photorealistic models purposely go out of their way to make 3D objects a lot different to the real world in order to fulfill some purpose.
3D Modeling is used in a wide range of fields, including:
Football, Track and Field, Swimming, Tennis
Film, Automotive, Video Games, Engineering
Mathematics, English, Literature, Accounts

Read the following statement and answer the question.
"When you make changes to 3D shape in Maya the information is stored in the channel box under the inputs section. A long list of all the tweaks are stored. It is important that you delete this history when you have finished modeling"
Why is it important to delete your history after you have finished modeling the object?
This will result in a smaller file size for your model and it will load much faster when Maya is initiated
It will prevent Maya from crashing.
It will make the 3D models look more appealing
This will result in a larger file size for your model and it will load much slower when Maya is initiated
This process projects a texture map onto a 3D object
