util.Vec3

Constructor

class util.Vec3(x, y, z)

Arguments:

• x –
• y –
• z –

:returns :

a vec3 object Vec3 should be assumed to only have .x, .y, and .z.

Methods

add(rhs)

Arguments:

• rhs – the vector to add to this vector

Returns:

vector sum of this vector and rhs

clone()

Returns:a copy of this Vec3.

Make a copy of this vector.

componentMultiply(rhs)

Arguments:

• rhs – the vector whose components need to be multiplied

Returns:

the vector with the component wise product

cross(rhs)

Arguments:

• rhs – a Vec3

Returns:

a Vec3 representing the vector product of this vector with rhs

div(rhs)

Arguments:

• rhs – scalar

Returns:

returns a vector scaled by (1/rhs)

dot(rhs)

Arguments:

• rhs – a Vec3

Returns:

a scalar representing the dot product of this vector with rhs

equal(rhs)

param rhs:any type returns:True if rhs is not a quaternion and x,y,and z fields

of this and rhs are identical. False otherwise.

rtype:bool

length()

Returns:the length of this vector

lengthSquared()

Returns:the length-squared of this vector

max(rhs)

param rhs:a Vec3 returns:a Vec3 where each component is the maximum of the components

of this vector and rhs For example, Vec3(3, 4, 7).max( Vec3(1, 5, 6)) returns a Vec3(3, 5, 7)

min(rhs)

param rhs:a Vec3 returns:a Vec3 where each component is the minimum of the components

of this vector and rhs For example, Vec3(3, 4, 7).min( Vec3(1, 5, 6) ) returns a Vec3(1, 4, 6)

mul(rhs)

Arguments:

• rhs –

Returns:

if rhs is a number, returns what scale(rhs) returns if rhs is a Vec3, it returns the componentMultiply(rhs)

neg()

Returns:negation of this vector

normal()

Returns:the unit Vec3 normal to this vector

reflect(normal)

Arguments:

• normal – The Vec3 across which to take reflection

Returns:

the Vec3 which is the reflection of this vector in the normal

scale(rhs)

Arguments:

• rhs – a scalar

Returns:

returns a vector scaled by the amount rhs

sub(rhs)

Arguments:

• rhs – the vector to subtract from this vector

Returns:

vector difference of this vector and rhs (this - rhs)
