The g_fCameraNear and g_fCameraFar parameters refer to the near and far dimensions of the view frustum. For an explanation see here:
To move models in a 3D application you can (conceptually at least) move the individual meshes or move the camera. In practical terms, you either manipulate the individual transformations required to position the individual models or you manipulate the transformation for the camera. This all boils down to changing the MODELVIEW matrix in OpenGL ES 1.1.
Use glMatrixMode(GL_MODELVIEW); to tell GL you want to alter this matrix then glLoadMatrix(your_matrix) to load a value for GL to use.
Hope this helps…
