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

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