OpenGl Examples
===========
`eclipse/` has the examples that eclipse can load (no longer updated).  Otherwise, everything uses android studio.

`OpenGL11examples/` has all the open GL 1.1 examples  No longer updated.

---

**OpenGL 2.0 examples:**

`HelloOpenGLES20` is Googles basic framework example.  2D square and triangle with touch events to spin the triangle  API 8+

`Opengl2ex1`  uses a renderer (lessonOne from http://www.learnopengles.com/android-lesson-one-getting-started/) and mainactivity to setup everything
    NOTE: this example may fail in the emulators, but works on a physical device.

`Opengl2ex2`  extends a GLsurfaceView to setup everything.  Again, use the Lessonone renderer.

**OpenGL 3.X examples:**

intended to get you started in OpenGL 3.0, but don't provide any depth of coverage.

`HelloOpenGLES30` is Googles basic framework example from 2.0, updated to OpenGL ES 3.0.  2D square and triangle with touch events to spin the triangle.  API 18+

`Opengl3ex1` is based on Opengl2ex1, with references changed to GLES30.  Note this may fail in emulators.
  
`Opengl3ex2` is based on Opengl2ex2, again with references changed. Note this may fail in emulators.

`Opengl3ex3` is from the OpenGL ES 3.0 Programing Guide, which can be found here: http://opengles-book.com/samplecode.html

`OpenGL30Cube` is Cube that spins and uses touchlistener to move up/down left/right.

`OpenGL30Pryamid` is Pyramid that spins and uses touchlistener to move up/down left/right.

`OpenGL30CubeTextureView` is the same renderer as OpenGL30Cube, except this uses a TextureView instead of surfaceView.  The TextureView has to setup all the openGL stuff, which takes a chunk of code to do.

`HelloOpenGLES31` is Googles basic framework example from 2.0, updated to OpenGL ES 3.1.  2D square and triangle with touch events to spin the triangle.  The setEGLContextClientVersion(3);  maybe wrong, since I could not find how to set it for 3.1. All other entries are set correctly.  API 21+

`HelloOpenGLES32` is Googles basic framework example from 2.0, updated to OpenGL ES 3.2.  2D square and triangle with touch events to spin the triangle.  The setEGLContextClientVersion(3);  maybe wrong, since I could not find how to set it for 3.2.  All other entries are set correctly.  API 24+

These are example code for University of Wyoming, Cosc 4730 Mobile Programming course and cosc 4735 Advance Mobile Programing course. 
All examples are for Android.
