Mapping texture to 3D objects with the OpenGL ES 1.x API

Texture mapping is a technique that overlays an image onto an object's surface to create a more realistic scene. This recipe covers how to add texture in OpenGL ES 1.x.

Getting ready

Readers are recommended to read the Drawing 3D graphics and lighting up the scene with OpenGL ES 1.x API recipe before going through this one.

How to do it...

The following steps create an Android project that demonstrates mapping texture to 3D objects:

1. Create an Android application named DiceG1. Set the package name as cookbook.chapter4.gl1x. Please refer to the Loading native libraries and registering native methods recipe in Chapter 2, Java Native Interface, if you want more detailed instructions.

2. Right-click on the project CubeG1, select Android Tools | Add Native Support.

3. Add three Java files, namely MyActivity.java, MySurfaceView.java, and MyRenderer.java under the cookbook.chapter4.diceg1 package. MyActivity.java and MySurfaceView.java are similar...
