Android OpenGL 2 ES how to generate an infinite 3D grid

Viewed 33

Hello I am quite new to OPEN GL ES android.

My task is to generate a 3D grid terrain that is infinite.

The task is tree planting. I am using an RTK system of pretty accurate coordinates that I convent into UTM and then mark points on my lines in the grid.(I won't go into further details).

I want to be able to draw virtual lines that are n metres away from each other on my screen using a given scale, for example 3 metres in the real world may be equal to 0.3 on the screen, my problem is if I have an area of 6 square kilometres in the real world, this will definitely require that my grid on the device is scrollable.

So how do I come up with an infinite scrollable 3D grid in order to solve that problem on android?

Thank you very much.
