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
[メタン分子] の化学構造を、３次元で表示するものを、作ってみた。
[メタン分子] は、1個の炭素原子([C])と、4個の水素原子([H])とで、できており、正四面体形の中心に炭素が、4個の頂点に水素が、というような構造に、なっているのだそうだ。
そこで、そのような位置関係になっている、5個の物体を表示するような、プログラムを作ってみた。このプログラムを動かしてみたら、下図のように、表示された。
－－－－－－－－－－
3 制作の過程
このプログラムを構成するモジュール群中の多くのものは、下記を構成するモジュール群から、そのままコピーして、流用した。
[断面画像を重ね合わせて、物体を３次元表示], 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
下記モジュールは、上記からコピーした後に、改変を施して、制作した。
[ ParametersContainer ]
[ ViewSpace ]
[ WorldSpace ]
[ WorldSpace ] から、新たに制作した下記モジュールを、呼び出すような形にした。
[ DrawingOneSphere ]
このモジュールは、原子1個に対する描画のための処理を行うためのものである。
3次元空間上の回転に関する座標変換処理に対しては、下記を新たに制作し、それを使用するようにした。
[ MatrixFor3DRotation ]
[ ParametersContainer ] が使用する、XMLデータ [XML_For_Parameters.xml] は、
[断面画像を重ね合わせて、物体を３次元表示], 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]
で、使用したものをコピーした後に、下記部分に対して、下記のように修正したものを、使用した。
