Public Class methods

new()

Returns a new, uninitialized FXHVec instance.

new(color)

Initialize with color

new(x, y, z, w=1.0)

Returns a new FXHVec instance with initial components (x, y, z and w).

new(other)

Returns a new FXHVec instance with contents initialized from other, where other is either an FXVec or FXHVec instance.

Public Instance methods

*(x)

Returns the product of this vector and the scalar x.

+(other)

Returns the sum of this vector and another vector

-(other)

Returns the difference, this vector minus another vector

-@()

Returns the negation of this

/(x)

Returns the quotient, this vector divided by the scalar x.

==(other)

Returns true if this vector is equal to other.

[](i)

Returns the ith element of this vector.

[]=(i, x)

Set the ith element of this vector to x.

cross(other)

Returns the cross product of this vector and other.

dot(other)

Returns the dot product of this vector and other.

hi(other)

Returns a new FXHVec, each of whose components is equal to the greater of this vector’s and other’s components, i.e. 

  self.lo(other) === FXHVec.new( [self[0], other[0]].max,
                                 [self[1], other[1]].max,
                                 [self[2], other[2]].max,
                                 [self[3], other[3]].max )
len()

Returns the length of this vector

lo(other)

Returns a new FXHVec, each of whose components is equal to the smaller of this vector’s and other’s components, i.e. 

  self.lo(other) === FXHVec.new( [self[0], other[0]].min,
                                 [self[1], other[1]].min,
                                 [self[2], other[2]].min,
                                 [self[3], other[3]].min )
normalize()

Returns the normalized version of this vector.

to_a()

Convert to an array

to_s()

Returns a stringified version of this vector
