How to add xyz points dynamically to generate a 3d graph?

[Daemon1992]

Hello, I have a need as follows:

1. Draw a three-dimensional coordinate system, and can achieve the zoom function.
2. Other modules constantly send me 3D coordinate points, which I need to draw on the coordinate system.
3. How should I deal with these massive data. Are they all in VBO? Can you give me some ideas or examples? Thank you very much.
