Hi, I'm new to VisAD. I try to run the tutorial programs in windows NT 4.0 and I have a problem to execute the 3D graph. (2D is alright). what shall be the problem? Thank you. Error Message: Exception in thread "main" java.lang.NullPointerException at P3_09.main(P3_09.java:98) P/S: The OpenGL.DLL file is in proper directory. Do I need DirectX from Microsoft to generate the 3D graph? Best regards,
visad
