Part II – interactive, real-time data visualization with mobile GPUs

Now we will complete our demo with the native code implementation to create our highly interactive Android-based data visualization application with OpenGL ES 3.0 as well as the Android sensor and gesture control interface.

The following class diagram highlights what remains to be implemented on the C/C++ side:

How to do it…

Here, we describe the implementation of the OpenGL ES 3.0 native code to complete the demo application. We will preserve the same code structure from Chapter 7, An Introduction to Real-time Graphics Rendering on a Mobile Platform using OpenGL ES 3.0. In the following steps, only the new codes are highlighted, and all changes are implemented in the main.cpp file inside the jni folder:

1. Include all necessary header files, including JNI, OpenGL ES 3.0, and the GLM library:

   #define GLM_FORCE_RADIANS
   
   //header for JNI
   #include <jni.h>
   ...
   
   //header for GLM library
   #include <glm/glm.hpp>
   #include &lt...
