Detect user's touches over an OpenGL square [duplicate] http://stackoverflow.com/questions/4154272/detect-users-touches-over-an-opengl-square OpenGL ES. There are as stated elsewhere essentially two approaches. You can figure out how the touch maps into your scene and test your objects mathematically. If your square is flat on as though you were drawing it in 2d then you can achieve.. something essentially like picking but adapted for the functionality available under OpenGL ES. For example clear your scene to black and draw your square in solid blue. Use glReadPixels to get the colour value at the touch location. If it's blue.. the touch is on the square. This is probably a more expensive way to test because it means an additional draw of the scene but it means that you don't have to implement any additional maths or other code beyond what GL supplies. The only slight..
