Introduction - If you have any usage issues, please Google them yourself
We aims to provide a simple, clear and practical description and example to developers, who are not experts in 3D interactive techniques, and would like to implement a 3D translation controller that behaves like it was built by an expert (Of course, you be the judge as to whether that is achieved). The article should at least help get you started with your own implementation. You may feel more comfortable with this source. We use the OpenGL 2.1.
