Are there simple iOS and Android examples for drawing lines set by opengl?
I've an iOS and Android application created with the same code from Qt 5. The app needs some functions for moving, rotating and Zoom In/Out my each edited object in canvas. My object is combined with lines set. The object with lines set maybe contained 60000 lines. I show those objects by image-cache now. But it seems not a good way. Hence, I want to try OpenGL to draw each line. But I don't know how to draw a lines set by opengl in Qt. I try the opengl example in my Qt folder. But its function is not what I want. And some object can't run on my iOS and Android. What should I do? Are there simple iOS and Android examples for drawing lines set by opengl? Can someone give me some kind of hint?
