I am having problems with lesson 34. I downloaded the code for it, but can't get it to run at all. I sort of skipped all the other tutorials, which I'm sure is part of my problem. I got lesson 1 to run without errors, where it opens a window and it's just black inside (which I'm pretty sure is what's supposed to happen.) I am using Eclipse. I did install jogl, although I can't say for 100% I did it correctly. When I try running lesson 34, a window opens, but nothing loads inside the window. I get an error saying: Exception in thread "Timer-0" javax.media.opengl.GLException: java.lang.UnsatisfiedLinkError: com.sun.opengl.impl.windows.WGL.GetPixelFormat(J)I at javax.media.opengl.Threading.invokeOnOpenGLThread(Threading.java:271) at javax.media.opengl.GLCanvas.maybeDoSingleThreadedWorkaround(GLCanvas.java:410) at javax.media.opengl.GLCanvas.display(GLCanvas.java:244) at com.sun.opengl.util.Animator.display(Animator.java:144) at com.sun.opengl.util.FPSAnimator$1.run(FPSAnimator.java:95) at java.util.TimerThread.mainLoop(Unknown Source) at java.util.TimerThread.run(Unknown Source) Caused by: java.lang.UnsatisfiedLinkError: com.sun.opengl.impl.windows.WGL.GetPixelFormat(J)I at com.sun.opengl.impl.windows.WGL.GetPixelFormat(Native Method) at com.sun.opengl.impl.windows.WindowsGLDrawable.choosePixelFormat(WindowsGLDrawable.java:82) at com.sun.opengl.impl.windows.WindowsOnscreenGLDrawable.lockSurface(WindowsOnscreenGLDrawable.java:203) at com.sun.opengl.impl.windows.WindowsOnscreenGLContext.makeCurrentImpl(WindowsOnscreenGLContext.java:57) at com.sun.opengl.impl.GLContextImpl.makeCurrent(GLContextImpl.java:134) at com.sun.opengl.impl.GLDrawableHelper.invokeGL(GLDrawableHelper.java:182) at javax.media.opengl.GLCanvas$DisplayOnEventDispatchThreadAction.run(GLCanvas.java:452) at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)
