Understanding Unit Vectors

Key Concepts

Essential elements of unit vectors:

Basic Properties:

  • Magnitude:

    A unit vector always has a magnitude (length) of 1

  • Direction:

    Points in the same direction as the original vector

  • Normalization:

    Process of converting a vector to its unit vector form

Applications

Common uses of unit vectors:

Practical Uses:

  • Game Development:

    Used for character movement and object direction

  • Physics:

    Representing force directions and velocities

  • 3D Graphics:

    Surface normals and camera directions
