RE: 3D Display Error

Dear Bill,

You are really helpful. I try to download the program and recompile and
execute it.

Exception in thread "main" java.lang.NullPointerException
        at P3_09.main(P3_09.java:215)

Same error message appeared without any modification.

Line 215 is :  " new P3_09(args); " under function main.

Best regards,
