What is a Mesh?
a collection of vertices, edges and faces that define the shape of a 3D model
a group of vertices that are linked together, making a shape
A collection of polygons, lightning and cameras
the process of calculating light and shadow information into the 3D geometry or texture of your model.
A (a) is the most basic part of a 3D polygon, when three or more vertices conect to make a visible surface.
What is a "Normal" defined as?
Why is it not recommended that a polygon has 3 sides, or more than 4?
Commonly, it requires more computer power to process these polygons, so the program may crash
3D animation only allows 4-sided polygons, as the system is not equipped to create 3-sided ones
Polygons with more or less than 4-sides usually cause issues when processing shadows, lights or textures.
False. A polygon can have any number of sides, and it is not recommended to keep them 4-sided
How can you switch the view to a Front (Orthographic) view? (2 valid answers, provide either)
(a)
What is "topology"?
The way that a 3D program processes how light behaves
The union of 2 or more vertices, also called "edge"
The way that polygons in a mesh are organized and connected to one another
The smallest part of a 3D model, where there is an intersection of three or more edges
True or False.
It is always mandatory to design a model in Perspective View, so that you always have depth of field and can see it in 3d.
True
False
If you wish to rotate the view you're working in, how can you do so? Please indicate 2 different ways to do it.
