A renderer is an engine that takes care of it.
#Opengl 2.0 tutorial android update#
What is a renderer? For example if you draw a triangle on the screen and you want to rotate it or say you have a line which you want to move across the entire scene, now using standard graphics programming you have to calculate and update the end coordinates ( called vertex coordinates) in every update. We can render any number of objects using OpenGL renderer. Now whatever we draw or manipulate would be on the OpenGL surface view. Therefore we need to create an OpenGL SurfaceView which is the main view of OpenGL animation and set the current ContentView to that surface view.

As such Android views are unsuitable for OpenGL operations. When we talk about OpenGL, we talk about hardware level drawing and manipulation. Images are drawn on Image Views, Button, EditText, TextView all are views which are placed over the ContentView of the main form. So far whatever Android we have learnt, we have used Android View to draw the objects.
But due to the broad range of the topics, we will stick to simple applications for each concept rather than going with a single App as we have done through most of our tutorials. As usual we will also see some use cases and how to's. This tutorial will be an afford to teach you the basics of Graphics and Animation in Android with as much fluidity as I can. OpenGL is an open source cross platform Graphics platform which utilizes device features and using the hardware features creates and manipulates graphics. Also animation must be bind with user input such as touch and sensors to make the environment more intuitive.

Many entertainment apps simply needs good animation capabilities and flicker free rendering of the animation objects. One of the factors is gaming and good apps. Users spend huge money on smart phones because of their utility factors.
