Re: [JAVA3D] Matrix4d bug!

rounding the values isn't quite correct because the rotation components are related. the get() method (if you look at the documenation) performs a normalization of the matrix before putting the 3x3 values into the parameter. sean > -Original Message- > From: Josh Richmond [mailto:[EMA

It is still the right type, but in the original 4x4 matrix we have (rounded for ease of viewing) 1 0 0 0 1 0 0 0 1 and in the 3x3 matrix (which was extracted via get) we have: 0 1 0 1 0 0 0 0 1 which is most definitely not the same transformation. Am I just thinking incorrectly about this?

You should be using GraphicsEnvironment object to .getDefaultScreenDevice() where you right, but then you should use this device to .setFullScreenWindow(frame) where you are right also. I tried exactly the same thing as you did, so here is my code to show you how did I get the GraphicsConfigurati
