4.01 Mastery Review

Coordinate Planes

Planes in 3D space defined by two of three coordinate axes; Used to define location & orientation of objects in 3D space.

World Orientation

Global Coordinate system that defines overall orientation of 3D space; Used for aligning & positioning objects in the scene; X,Y, & Z axes remain constant for all objects

Object Orientation

Local coordinates systems specific to each 3D object; Movement, Rotation, & scaling are based on object orientation; X,Y, & Z axes relative to object itself

Absolute Scale

Fixed size of an object measured in absolute units

Relative Scale

SIze of an object in relation to another object or the project scale; Used in maintaining proportionality & relative sizing within a scene
