Hi, everybody
I am facing the next problem:
I´ve made a simple 3D design program. In the 3D visualization window I want to rotate the view with the help of the mouse. I rotate around X and Y fixing Z moving Up and Down. The problem is that when I have made some movements occurs that if I move the mouse to right the image moves left…Do you understan (I hope because my English is not as good as should be). I want something that allows me moving only the object and leaving the axes fixed. I´ve found something about a virtual Trackball but I want to know the theory…
Do you know where can I find that information and/or code?.
Thanks
