I've preferred FLTK for easy development of GUI tool. It has function to treat OpenGL easily, but it doesn't provide box but only window as "Fl_Gl_Window". If you need OpenGL in the box, since it is not supplied as its package, so thus you must use the "Fl_Gl_Box". 簡単なGUI toolを作るときには、ながらくFLTKを愛用してきました。 特にOpenGLを簡単に利用できるので、ちょっとした実験には最適です。 しかし、FLTKのパッケージには、OpenGL用にWindowを作るものはあるのですが、Box (Windowの中に配置される子Windowのようなもの)はありませんでした。そのような状況では、Fl_Gl_Boxを使う必要があります。 Unfortunately, it had been lost in the internet space (the original author of the library had used GeoCities and the site had been vanished), but I found it here. 残念ながら、Fl_Gl_Boxの配布サイトは消えてしまったようです。 しかし、幸運にも Fl_Gl_Boxのソースを以下に発見しました。 <http://www.gnu-science.org/phpBB3/viewtopic.php?f=7&t=45#p1268> I'm feeling lucky :-) ラッキーですね。 fltk memo opengl 0 2009-08-04T20:20:08+00:00 1220 blue_stole 1569 184 2009-08-04T20:08:00+00:00 22d04c60-e557-47b4-8393-b1e37f6d6a4d 2009-08-04T20:20:08+00:00 9

At first, you download files of Collada from here <http://sourceforge.net/projects/collada-dom/> It includes collada-dom, but you must build it before using. To build the package, you must unpack the zip and move to dom/ directory.

Through my investigation for writing about the parallel computing, I found there are many "incoherences" and "inconsistencies" all over various terminologies regarding parallel computing. I guess surrounding environment is so fastly changing, the center of excellence of this research field has been moved very frequently. Most of significant works had been done in the era of sequential computing. But for very near future, we will be going into the era of parallel computing. The terms that had been spawned in the hypothetic world would get real body and require coherent and consistent definition of themselves. thoughts parallel computing 0 2009-06-28T02:38:15+00:00 1198 blue_stole 1540 171 2009-06-28T02:18:00+00:00 7ddf5245-8da1-49d1-85f9-3f9e12443f51 2009-06-28T02:57:19+00:00 9
