Android uses OpenGL ES to display images

The android framework provides a large number of interactive and powerful graphic user interfaces. But if you want more painting on the screen or 3D display, you need to use different tools. OpenGL ES api provides a large number of tools to display high-end animated images.

The following describes how to use OpenGL Es to develop applications. Including creation, painting objects, Moving Elements, and control response touch screen input. The instance Code uses OpenGL ES 2.0ApI. This is the most widely used version.

Note: Do not use the 1.x method in 2.0.

This part mainly involves six aspects:

1. Create an OpenGL ES environment.

2. define the shape.

3. Painting shape.

4. Application Engineering and photo view.

5. Add activities.

6. Respond to touch screen events.

We will detail the details of each point in the future.
