Lesson 7 123 design

1. 1
Lesson 1
(Introduction to 3D design and Modelling)
Key Vocabulary: -
Perspective: Seeing an object on a flat surface as it is seen by the
eye, getting smaller as it gets further away from the viewer.
Orthographic view: Seeing a 3-dimensional object in 2 dimensions.
Value: What something is worth.
Dimension: The space something occupies, height, width, length.
Polygon: A closed shape that has three or more, usually straight, line
segments.
Edge: the outside limit of an object, area or surface.
Face: A flat surface of a geometric solid.
Polygon mesh: A group of polygons which are connected by shared
vertices.
- 3D and 2D
● 3D stands for three-dimensional.
● It means we can now see that an object has a width,
height and depth (length).
● What we see in the real-world is 3D.
● Our eyes and brain work together to show you how near or
far something is.
● We have 3D glasses for 3D movies.
- 3D design is used in many fields such as:
● Medicine
● Architecture and Design
● Forensics
● The Military
● Pilot Training
● Movies, Video Games, Virtual Reality
– 3D and polygons

2. 2
A polygon is any closed 2D shape made with more than 3 straight lines.
3D models are created in the workspace using polygons
Polygons Mesh is a group of polygons which are connected by shared
vertices l
