Hi guys,

I'm using the GLU.gluProject() method with double parameters but I don't know why the in the SwingCanvas nothing is show. and when I try to resize the window the following exception is thrown:

Exception in thread "AWT-EventQueue-0" javax.media.opengl.GLException: GLEventListener org.jzy3d.plot3d.rendering.view.Renderer3d@17fa65e already initialized: AWT-GLJPanel[ com.jogamp.opengl.impl.windows.wgl.WindowsOffscreenWGLDrawable, GLAnimatorControl: null, GLEventListeners num 1 [org.jzy3d.plot3d.rendering.view.Renderer3d@17fa65e[init true], ]]

It seems the same problem that Martin mention On Nov 06, 2010; 12:04pm.

I'm working with:
- the jzy3d 0.9 version (al least is what it is write in the build.xml file)
- jogl2
-Win7 (64 bit)

Are you sure that the GLU.gluProject()  method work properly even with double parameters?

Thank you in advance!!
