Java で openGL (JOGL 1.0) を実行すると、2 分後にアプリが動作を停止し、ウィンドウがフリーズします。
ここで、javaw.exe が1161536 KBを超えていることがわかります。これは正常ではないと思います。
では、何が原因なのでしょうか?
コードの核心であるdisplay()メソッドは次のとおりです。
Class Renderer { ...
public Renderer ()
{
this.addGLEventListener(this);
addKeyListener(this);
addMouseListener(this);
// put the agent in a specific location inside the room
this.m_firstPersonLocation = new Point3D(750 , 200 , 5000);
