• vect3
  • Vect3() Initialize with three, one, or zero arguments
  • strval() Get string value of a Vect3
  • add() Add some Vect3
  • sub() Substract two Vect3
  • mul() Multiply Vect3 with scalar or vice versa
  • div() Divide Vect3 with scalar
  • dot() Dot two Vect3
  • cross() Cross two Vect3
  • len() Get length of a Vect3
  • unit() Get unit vector of a Vect3
  • neg() Get negative of a vector
