  STARTING OUT IN3D MODELING  CG and/or CGI – Acronyms that stand for Computer Graphics and/or Computer Graphics Imagery. Terms used interchangeably.  Process of creating and/or arranging objects in a file. Further editing can include adding lighting, special effects, textures, and animation  3D – Shorthand for three-dimensional. Often associated with CG and is a file that has an environment that recognizes the X, and Z axis. Compared to programs such as Adobe Photoshop and Adobe Illustrator which are 2D (two-dimensional) graphical environments, Maya and other 3D software packages introduce the Z-axis to provide depth.

  POLYGONS  Polygon geometry– Combination of faces that are created through sharing vertices and edges.  Maya provides pre-made polygons shapes that are referred to as primitives or ‘prims’  Polygon modeling is where many modelers begin.  Box Model – Process of starting with a basic prim and building the 3D model out from there.

  PARTS OF A POLYGON Face – Flat area of the Polygon, created and contained by 4 Edges.  Edges – Lines that create a face. Are connected by Vertex Points  Vertex (Vertices) – Points that act as connectors for Edges
