In-Depth Information
This example opens a window with a red background and prints lines similar to:
Using glCreateContext()
Using wglCreateContextAttribsARB()
OpenGL version: 3.2.0
OpenGL renderer: GeForce GTX 560/PCIe/SSE2
OpenGL vendor: NVIDIA Corporation
The OpenGL context version matches the version speciied in the call to
glCreateContextAttribsARB()
.
There's more…
Setting a pixel format of a window more than once is not allowed in WinAPI. Hence, we
use a temporary invisible window to create the irst rendering context and retrieve the
extensions. Check out the ile
OpenGL3.cpp
from the
1_OpenGL3
example for further
implementation details.

Initializing OpenGL ES 2 on Android
Initialization of OpenGL on Android is straightforward when compared to Windows. There
are two possibilities to create an OpenGL rendering context in the Android NDK: use EGL API
(
http://en.wikipedia.org/wiki/EGL_(API)
) from NDK directly, or create a wrapper
Java class based on
android.opengl.GLSurfaceView
. We will choose the second option.
Getting ready
Make yourself familiar with the interface of the
GLSurfaceView
class at
http://
developer.android.com/reference/android/opengl/GLSurfaceView.html
.
How to do it…
1.
We extend the
GLSurfaceView
class in the following way:
public class GLView extends GLSurfaceView
{
