Why don't you sit on this and rotate? Oh you don't know how? Well allow me to elucidate. Srsly tho, rotation math is pretty damn important shit, so pay attention.

Topics

Part 1

  • Angles, degrees, radians, and π
  • Sine, cosine, and the unit circle
  • Arcsin, arccos
  • SOH-CAH-(TOA)

Part 2

  • Derivation of rotation formula: arcsin/arccos
  • Angle sum theorem (trig identity)
  • Derivation of rotation formula: angle sum theorem
  • Derivation of rotation formula: vector derivation
  • Using rotation to solve A3 homework (rotate to get plank normal)

Part 3

  • Vec2 rotation functions
  • Basic rotation of model
  • Implementing rotation into Drawable pipeline
  • Optimizing pipeline for rotation
