NAME
SecondLife::Rotation - Second Life's rotations (quarterions with a non-standard representation)
VERSION
version 0.900
SYNOPSIS
use SecondLife::DataTypes qw( slrot slvec );
my $rot1 = SecondLife::Rotation->new( "<0,0,0,1>" ); # create a null rotation
my $rot2 = slrot "<0,0,0,1>"; # the same
my $rot3 = SecondLife::Rotation->new( x=>0, y=>0, z=>0, s=>1 ); # the same
my $rot4 = SecondLife::Rotation->new( Math::Quaternion->new( 1, 0, 0, 0 ) ); # The same
# Rotate the specified vector by the rotation and return the new vector
my $vec = $rot1->rotate_vector( slvec "<1,2,3>" );
print "$rot1\n"; # Prints <0, 0, 0, 1>DESCRIPTION
This is a subclass of Math::Quaternion. The constructor can accept the Second Life string representation of a rotation, x, y, z, s key/value pairs, a hashref to be passed to Math::Quaternion->new, or a Math::Quaternion object.
Stringifying produces the SecondLife form, not the Math::Quaternion form.
Rotate_vector expects and returns a SecondLife::Vector object.
There are x, y, z, and s accessors.
Otherwise, this is the same as a Math::Quaternion object. If you want to know more about the operations available to, please see its documentation.
CONSTRUCTOR
new( Str $slrotation ) returns SecondLife::Rotation
new( :$x, :$y, :$z, :$s ) returns SecondLife::Rotation
new( Math::Quaternion $quaternion ) returns SecondLife::Rotation
new( HashRef $args ) returns SecondLife::Rotation
Construct a SecondLife::Rotation object from either the SL string representation, or a hash with keys for the individual elements, or a Math::Quaternion object, or a hashref to pass to Math::Quaternion's constructor.
ATTRIBUTES
our Num $x is rw
The X value of this rotation.
our Num $y is rw
The Y value of this rotation.
our Num $z is rw
The Z value of this rotation.
our Num $s is rw
The S value of this rotation.
METHODS
stringify() returns Str
Returns the Second Life string representation of this rotation
rotate_vector( SecondLife::Vector $vector ) returns SecondLife::Vector
Rotates $vector by this rotation and returns the resulting vector. This does not mutate.
