Transformations and 3D Models

Each vertex in a 3D model contains information on the:

• X, Y, and Z coordinates

• X and Y coordinates only

• Z coordinate only

• X coordinate only

When using a 3D modeling program, extruding means that a student:

• Subtracts one 3D object from another

• Creates a 2D shape and give it thickness

• Combines two objects into one object

• Takes a 3D object and changes it to a 2D object
