public void onDrawFrame ( GL10 glUnused )
{
// Set the viewport
GLES30.glViewport ( 0, 0, mWidth, mHeight );
// Clear the color buffer
GLES30.glClear ( GLES30.GL_COLOR_BUFFER_BIT );
// Use the program object
GLES30.glUseProgram ( mProgramObject );
// Set the vertex color to red
GLES30.glVertexAttrib4f ( 0, 1.0f, 0.0f, 0.0f, 1.0f );
