Method Details

[hide private]

sub(self, v)

source code

Vector Subtraction

returns self-v

mul(self, s)

source code

Scalar Multiplication

returns self*s (scalar multiplication)

cross(self, v)

source code

Cross product.

self cross v

mag(self)

source code

length

return the magnitude(length) of the vector.

magSqr(self)

source code

Square of the magnitude.

this is faster than calling mag(), and is often just as useful.

norm(self)

source code

normalize

returns a unit vector in the same direction as this vector.
