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?
