1 はじめに
これ以降に記述されている内容は、このようなコンピューター・プログラムを制作した、というような事を、ただ、述べているに過ぎない。
以下の記述を読んだ人が、それを単に参考にする、というのであれば、問題は無いと、思われる。
しかし、記述されている内容に沿って、その人が、そこに記されているのと同様の制作や作業を行った際に、その制作、作業、コンピューターの作動の結果、使用されたコンピューター等、様々な方面において、何らかの問題が発生しない、という保証は、全くない。
その制作、作業、コンピューターの作動の結果、その人や、その人が所属している組織、その人が使用した様々な機器、インフラストラクチャー等の、身の上にどのような事が起ころうとも、私は一切、責任を負わない。
このプログラムは、Python(パイソン) 言語を使って、記述されている。
－－－－－－－－－－
2 どのようなものを作ったのか
これまでに、下記の２個のモジュール群を作成した。
モジュール群(1)
[メタン の化学構造を、３次元表示する], Python(パイソン) 使って作ってみた ,ソースプログラムリスト あり
モジュール群(2)
[動画を作る , 動画を読み込む] , Python(パイソン) 使って作ってみた ,ソースプログラムリスト あり
上記で作成されたモジュールを流用して、
[メタン の化学構造が、回転していく様を、描く、動画] を 作製するモジュール群
を、作ることができるのではないかと、考え、そのようなものを、作ってみた。
このモジュール群中の、[ TestVideoHandling ] を起動すると、以下のように、動いていく。
(1) 動画データを作成
下記のような処理を、90回、繰り返す。
下記(Fig 1) のイメージデータを読み込み、
そのイメージデータ上に、メタン分子の構造を表す画像を、書き込み、
それを、1個の動画フレームデータとして、書き出す
メタン分子の角度を、少し、変える
このようにして、90個のフレームから成る、動画データが、作成される。
(2) 動画データを読み込み、特定のフレームの内容を、画像データとして、書き出す
(1) で作成された動画データを、最初のフレームから順に、読み込み、特定のフレームにさしかかったら、そのフレームの内容を、画像データとして、出力する。（下記 Fig 2 , Fig 3 , Fig 4, Fig 5, Fig 6 )
－－－－－－－－－－
3 モジュール群の構成
このモジュール群は、以下のモジュールより、構成されている。
(1) DrawingOneSphere
(2) ErrorProcess
(3) HiddenLineRemoval
(4) ImageDataTwoDimensionHandlingV2
(5) MakeImageData
(6) MatrixFor3DRotaion
(7) TestVideoHandling
(8) VideoHandling
(9) ViewSpace
(10) WorldSpace
上記のうち、下記モジュール
(1) , (3) , (6) , (10)
は、
[メタン の化学構造を、３次元表示する], Python(パイソン) 使って作ってみた ,ソースプログラムリスト あり
より流用した（コピーして作った）。
上記のうち、下記モジュール
(4) , (8)
は、
[動画を作る , 動画を読み込む] , Python(パイソン) 使って作ってみた ,ソースプログラムリスト あり
より流用した（コピーして作った）。
上記のうち、下記モジュール
(2)
は、
Python(パイソン) ,ソースプログラムリスト あり ,プログラム作ってみた ,[エラー処理] を 行う
で説明したものを、用いた。
上記以外のモジュールの内容について、以降に記す。
