Hello java professionals! Here is an «introduction» to my problem:

Due to my task, I must implement a project for clusterization and visualization of some data set. I haven't troubles with the clusterization yet, but need help with the visualization.

I chose JOGL (Java OpenGL) for my project. So, my question is concerned with JOGL.

At the beginning I decide to practice in JOGL. I just want to draw a white rectangle on the black background. Here is my source code:



Now the fact of the matter. When I resize a main window, I got a noize (I placed the result in the attached file). Any suggestions for the problem-solving? Maybe I need to implement another OpenGL functions within display() or reshape() functions?

Thanks in advance!
Michael.

Welcome to JavaRanch.

I don't see any attached image, but when I run the code it gets resized just fine - no artifacts, no visual noise.

@Ulf Dittmer

Thanks for the reply. It's strange that message doesn't have an attached file.

I'll try to post it in this message.

@Ulf Dittmer,

thanks again. I just checked the application on another machine. It works properly there.

Good to hear. OpenGL/JOGL relies heavily on graphics card behavior, so there are more variables than just the OS version and JVM version...
