Mario, The first aspects (from a Java 3D point of view) that I'd look at would be the size of your texture map for the earth model and how are you creating your earth sphere (how many vertices does it have?). The TNT2 isn't exactly a fast video card by today's standards and I suspect it would be sluggish when using a large texture. Try replacing that texture with a 16x16 solid color image and see what difference you get in frame rate.
>From casually looking at your screenshot I'd expect a better frame rate than you are reporting, even on a TNT2. You also don't mention if you are running OpenGL or DirectX, what operating system, which version of Java 3d, etc. In the demos you should find "FPSCounter" to give some idea of how to implement your own frame rate counter. j3d.org note: Justin - we really should have an easy to find example of how to make a frame rate counter in the j3d.org FAQ. This is a very basic aspect of Java 3D that most everyone ends up wondering about when they are first learning Java 3D (I don't think Sun's example code was included until Java 3D version 1.3). - John Wright Starfire Research "ZACZEK, MARIUSZ P.
