Pack Method in Ruby

"pack" method is to show us binary format of object in Ruby Program.

Recently I want to create binary data from text file with Ruby.
Ruby has powerful regexp and convenient methods to be equip.

Therefore I try to create file and to store binary data.
But, I wonder how to store binary data!

Ruby provides the way to store for file is only text format.
I am in trouble.

I study a reference of Ruby.
It describes following.

Firstly You must use "pack" of Array Class method in order to know text of binary format of object

Secondly You store text of binary format in file.


Example code is next.

 file << [10].pack("i")

Playing Game in iMac

Since I buy a iMac recently, I enjoy iMac life.
iMac is very beautiful and small.
My house is narrow, Therefore I like that iMac have only display, keybord and mouse without box.


But There is one problem, It is that game for iMac is just a little.
If I live in USA, no problem.
In actuality I live in Japan, I can not buy games for iMac.

I want to buy Spore and AOE3 for iMac.

Disk Checker Ruby Program

I wrote ruby program to work checking disk and reporting result.

It is following code

#!/usr/bin/ruby
require 'net/smtp'

if ARGV[0] == nil then 
  print "usage : " + $0 + " directory\n"
  exit(1) 
end

print "check directory " + ARGV[0] + "\n"

cmd = "du -h -c " + ARGV[0]

array = []

IO.popen(cmd, 'r+') do |pipe|
  t = pipe.read
  t.gsub(/(?:[0-9]+(\.[0-9]*)?|(\.[0-9]+))([eE][-+]?[0-9]+)?\w/){|s| 
    array.push(s)
  }
end

mailstring = "total = " +  array.last() + "\n"

Net::SMTP.start( 'severname', portnumber ) {|smtp|
  smtp.send_mail(mailstring, "from@localhost", "to@localhost")
}

Grouping Polygon

I think new 3d format using my campany.

This new 3d format is more than just to display 3d cg data.
In other words, this format does not have only coordinate, connectivity and color value, but grouping polygon.

Grouping polygon allow user to sign polygons.

dotX format

Now, I think new format of 3d shape data.

And I study other application's data formats.
First, I study dotX, is format of softimage|XSI.

dotX is perfect for 3dcg data, has not only shape data but also animation , bone and so on.

Shape data in dotX is named SI_Mesh, It involves volume and face group.
In addition, It has triangle strips.
